SUMMARY:CGCA Seminar - Abygail Waggoner
DESCRIPTION:What’s Feeding Terrestrial Planets? JWST Observations of Protoplanetary Disk\nDr. Abygail Waggoner\nUniversity of Wisconsin-Madison \nThe formation of terrestrial\, or earth-like\, planets is thought to occur in the inner few au of protoplanetary disks\, but what is the composition of the dust and gas that forming-planets may inherit? In this talk\, we’ll discuss how the James Webb Space Telescope can be used to measure the chemical composition of protoplanetary disk gas and how models can be used to understand the evolution of material throughout planet formation. We will focus specifically on results from the ALMA/JWST survey of Gas Evolution in PROtoplanetary disks (AGE-PRO) large collaboration (PI: Ke Zhang). AGE-PRO uses a combination of ALMA observations\, JWST observations\, and chemical disk models of thirty protoplanetary disks spanning the planet formation process (~0.5 to 6 Myr old) to gain a (relatively) comprehensive picture of gas and dust evolution of planet formation.

SUMMARY:Physics Colloquium – Gabriel Freedman
DESCRIPTION:Speaker: Gabriel Freedman\, PhD Candidate – UWM Physics \nLow-frequency Gravitational Wave Searches and Data Analysis with Hamiltonian Sampling \nThe pulsar timing array community has found evidence for a correlated stochastic signal following the Hellings-Downs pattern indicative of an isotropic stochastic gravitational-wave background (GWB). The most likely source of such a background is a population of supermassive black hole binaries\, and particularly loud individual sources could be detected in future datasets. \nWe present work done towards performing joint Bayesian searches for both the GWB and single sources utilizing the Hamiltonian Monte Carlo sampling algorithm to efficiently explore these complex parameter spaces. We end by discussing applications of these methods to data analysis for the upcoming Laser Interferometer Space Antenna mission. \nLocation: Kenwood IRC 2175 \nTime: 10:00AM – 12:00PM \nDate: April 17th\, 2025

SUMMARY:Biophysics Talk - Professor Abhishek Singharoy
DESCRIPTION:Abhishek Singharoy\, Assistant Professor\, Center for Applied Structural Discovery\, Biodesign Institute at Arizona State University. \nComputing Free-Energy Landscapes from Molecular Dynamics Simulations \nThe most probable pathways of structural transition in biomolecular complexes follow minimum free-energy pathways.  Employing an implicit scheme for solving the Langevin dynamics equation\, called the string method\, these pathways are determined for structural transitions in molecular motors. The underlying multidimensional thermodynamic landscape is probed to determine experimentally measurable quantities such as\, binding affinity\, turnover rates\, and energy conversion efficiencies.

SUMMARY:CGCA Seminar: Dr. Christine Lynch
DESCRIPTION:The Leonard E Parker Center for Gravitation\, Cosmology and Astrophysics holds frequent seminars on a broad range of ongoing cosmology and gravitation research topics. Unless otherwise noted\, seminars are on Friday afternoons at 1:00 PM in KIRC 2175; there is a gathering for a brown bag lunch at 12:30. \nChasing Low Frequency Radio Bursts from Magnetically Active Stars \nDr. Christine Lynch\,  University of Sydney \nFlaring activity is a common characteristic of magnetically active stellar systems. These events produce emission throughout the electromagnetic spectrum\, implying a range of physical processes. A growing number of objects are observed to exhibit short-duration\, narrow band\, and highly circularly polarised (reaching 100%) radio bursts. The observed polarisation and frequency-time structure of these bursts points to a coherent emission mechanism such as the electron cyclotron maser. Due to the stochastic nature of these bursts and the sensitivity of current instruments\, the number of stars where coherent emission has been detected is few\, with numbers limited to a few tens of objects. Observations of a wider sample of active stellar systems are necessary in order to establish the percentage that exhibit coherent radio bursts and to relate occurrence of these bursts to basic physical parameters of these stellar objects. New wide-field\, low frequency radio telescopes will probe a frequency regime that is mostly unexplored for many magnetically active star systems and where coherent radio emissions are expected to be more numerous. We are currently carrying out a targeted survey of M dwarf stars with known bright radio flares using the Murchison Widefield Array. The goal of this project is to confirm the flare detections made with single dish telescopes in the 1970s and to better constrain stellar flare rates at 154 MHz. In this talk I will present a recent detection of  four coherent flares from the nearby M dwarf star UV Ceti and disscuss future prospects of detecting a larger sample of M dwarfs using what we know about our UV Ceti observation.

Such nuclear clusters are the densest stellar systems observed in the local universe\, representing a natural environment where compact object binaries can dynamically form\, harden and merge. I will discuss the dynamical processes that lead to the merger of black hole binaries in nuclear clusters in connection to the origin of the binary black hole mergers recently detected by Advanced LIGO. I will show that nuclear clusters can produce a significant population of black hole binaries that merge in the local universe\, and that these binaries have clear differences in the statistical distributions of their properties (e.g.\, mass\, eccentricity) when compared to those formed either in globular clusters or through isolated binary evolution. Dynamical processes in nuclear clusters are also found to form very naturally high mass black hole binaries similar to the one that produced GW150914\, the first merger signal detected by Advanced LIGO.

Unless otherwise noted\, seminars are on Friday afternoons at 1:00 PM in KIRC 2175; there is a gathering for a brown bag lunch at 12:30. \nGeneralized temperature and accelerated dynamics \nMorgan Lynch\,  UWM Graduate Student \nI will present recent work involved with the computation of the temperature registered by an Unruh-DeWitt detector coupled to a Hadamard renormalizable quantum field and moving along an arbitrary accelerated trajectory in curved spacetime. Then\, focusing on the temperature due to acceleration\, i.e. the Unruh effect\, I will present an effective Fermi theory of acceleration-induced interactions. This accelerated quantum dynamics provides a framework for computing a wide class of observables to probe the physics of high acceleration. General expressions for the emission rate\, multiplicity\, power\, spectra\, and displacement law of particles undergoing time-dependent acceleration and transitioning into a final state of arbitrary particle number will be presented.

First\, resonant 3-mode interactions within Sun-like stars can be excited by close exoplanets and may explain the dearth of short period/high mass hot Jupiters. Second\, non-resonant interactions within neutron stars in compact binaries are driven throughout the gravitational wave inspiral. This extra source of dissipation modifies the gravitational waveform’s phase and should be detectable with current instruments assuming reasonable saturation profiles. While detectability in binary neutron star systems will be discussed in some details\, the impact of nonlinear tides in both systems should be observable over the next decade. The audience will also learn the difference between gravity waves and gravitational waves.

Absorption line spectroscopy is an important tool for understanding the multiphase nature of HI\, especially in our own Galaxy where high sensitivity and resolution can be achieved. In this talk\, I will present results from 21-SPONGE: the largest and most sensitive survey for Galactic HI absorption using the Karl G. Jansky Very Large Array. Our excellent sensitivity enables us to detect unexpectedly warm neutral gas at T=7000 K\, which suggests a new found influence of the Lya radiation field density in the ISM. To isolate the dominant physics behind our observed spectral lines\, we analyze 1000s of synthetic HI spectra from 3D numerical simulations from Kim et al. (2014) using machine learning and derivative spectroscopy. For the first time\, we statistically quantify the ability of Gaussian spectral lines to recover simulated clouds and their important physical properties\, such as temperature and density. Furthermore\, with the biases of our analysis tools in hand\, we measure the fractions of local HI in the cold\, warm and thermally-unstable gas phases.

We identify ~65 000 star-forming regions (i.e. FUV sources)\, measure each galaxy’s luminosity function\, and characterize the relationships between the luminosity function slope (α) and several global galaxy properties. We find that α correlates with global star formation properties\, where galaxies with higher star formation rates and star formation rate densities (ΣSFR) tend to have flatter luminosity function slopes. We hypothesize that the flatter slopes in high ΣSFR galaxies is due to higher gas densities and higher star formation efficiencies which result in proportionally greater numbers of bright star-forming regions. In addition\, we create a composite luminosity function composed of star-forming regions from many galaxies and find a break in the luminosity function at brighter luminosities. However\, we find that this break is an artifact of varying detection limits for galaxies at different distances. Finally\, we introduce the Census of the Local Universe (CLU) galaxy survey designed to find tens-of-thousands of new galaxies for targeted aLIGO gravitational wave counterpart searches and demonstrate how these additional star formation laboratories can add to our understanding of how stars form in the local Universe.

Detecting these waves involves sophisticated data analysis techniques centered around matched filtering\, requiring large banks of accurate GW templates\, as well as methods to distinguish between candidate events triggered by true GW signals\, and those caused by non-Gaussian noise (“glitches”). Focusing on searches for inspiralling neutron-star black-hole binaries\, we present here a method to improve the accuracy of analytical (Post-Newtonian (PN)) waveforms by the inclusion of “pseudo” Post Newtonian terms determined by calibrating the PN waveforms to more accurate (though computationally expensive) fiducial waveforms. We further introduce a machine-learning based approach to segregate candidate events\, and show that\, by identifying and exploiting a number of their key properties\, we can improve on existing classification methods.

Neutron stars can be well-modelled as simple barotropic fluids during the part of binary inspiral most relevant to gravitational wave astronomy\, but the crucial geometric and mathematical consequences of this simplification have remained computationally unexploited. In particular\, Carter and Lichnerowicz have described barotropic fluid motion via classical variational principles as conformally geodesic. Moreover\, Kelvin’s circulation theorem implies that initially irrotational flows remain irrotational. Finally\, the acoustical metric formulations of Christodoulou and Unruh can be utilized to evolve the Hamiltonian of a fluid element. Applied to numerical relativity\, these concepts lead to novel Hamiltonian or Hamilton-Jacobi schemes for evolving fluid flows in numerical general relativity.

The variational principle gives a lower bound to the rate of exponential growth in the case of instability.

These neutron stars are believed to be the end-product of binary evolution\, i.e. the recycling scenario\, in which an old neutron star accretes matter and angular momentum from a close stellar companion for an extended period of time\, while being observable as an X-ray binary. A handful of MSPs are  detected in very compact orbits (orbital periods between  2 − 9 hr)\,  around low-mass He WDs with masses below 0.25 Msun and surface gravities 5 < log g < 7\, the so-called extremely low-mass helium white dwarfs (ELM WDs). \nToday we know of the existence of more than 80 ELM WDs\, with the majority of them in a binary system with a more massive CO WD. The increasing number of discovered ELM WDs reveals that they are formed in different environments\, from the Galactic disk to open and globular clusters. ELM WDs are most likely the result of binary evolution as they cannot be formed from single stars within a Hubble time. The new wealth of data raises questions regarding the puzzling presence of metals in the atmospheres of young bloated ELM proto-WDs and the newly discovered pulsations in three ELM proto-WDs.  The current available evolutionary models fail to explain such properties. In this talk\, I will present the latest theoretical efforts  regarding the formation and evolution of ELM WDs.

Most DNS systems found previously have short orbital periods\, rapid spin periods\, and eccentric orbits. However\, J1930-1852 has the longest known spin period (185 ms) and orbital period (45 days) yet measured among known\, recycled pulsars in DNS systems\, implying a shorter than average and/or inefficient recycling period before its companion when supernova. The system’s relativistic advance of periastron implies its total mass is consistent with other DNS systems and puts constraints on the pulsar and companion masses. PSR J1930-1852’s spin and orbital parameters challenge current DNS population models and make the pulsar an important system for further investigation. \nThe Green Bank North Celestial Cap (GBNCC) survey\, also operating at 350 MHz\, has been prolific in pulsar discoveries over the past six years\, in large part\, due to the efforts of undergraduate students here at UWM and institutions across the US and Canada. Many of these discoveries show inherent scientific promise and the young scientists involved gain valuable research experience.

Unless otherwise noted\, seminars are on Friday afternoons at 1:00 PM in KIRC 2175; there is a gathering for a brown bag lunch at 12:30. \nEjective Feedback and the Gas Around Galaxies\nDr. Aleks Diamond-Stanic\,  University of Wisconsin – Madison \nOur understanding of galaxy evolution centers around questions of how gas gets into galaxies\, how it participates in star formation and black hole growth\, and how it is returned to its galactic surroundings via feedback.  On a global scale\, measurements of the baryon density and the stellar mass function indicate that only 5% of baryons have formed stars by the present day\, and this suggests that feedback from massive stars and supermassive black holes must prevent gas from forming stars in both low-mass and high-mass dark matter halos.  I will present observational results on the geometry and kinematics of outflowing and inflowing gas around galaxies\, including measurements of ejective feedback that is capable of shutting down star formation by removing the cold gas supply.  These results have broader implications for how gas is consumed and expelled at the centers of massive galaxies and for the limits of feedback from stellar radiation and supernovae.  I will also discuss prospects for characterizing the physical properties of gas in and around galaxies using multi-wavelength spectroscopy with existing and future facilities.

It is difficult to observe from Earth\, except during a ring-plane crossing\, when the rings are viewed edge-on. These events occur only about every 15 years.  In a ring-plane crossing observed by Hubble Space Telescope in August 1995\, an asymmetry in brightness between the east and west sides of the rings was observed.  We have shown that the inclination of the F ring relative to the main rings caused the asymmetry\, because the F ring can obscure the east and west side of the main rings to different extents. This discovery afforded an opportunity to measure the vertical thickness of the F ring\, which we found to be 13 +/- 7 km.  Since 2004\, the F ring has been observed extensively by the Cassini spacecraft\, and since Cassini crosses the ring-plane twice each orbit\, several ring-plane crossings have been observed. We apply the same techniques used to analyze the Earth ring-plane crossing to the best of these observations\, which was made Dec 1-2\, 2005.  Finer resolution and more rapid sampling allows us to probe the vertical structure of the F ring in much greater detail.

DESCRIPTION:The Leonard E Parker Center for Gravitation\, Cosmology and Astrophysics holds frequent seminars on a broad range of ongoing cosmology and gravitation research topics.

The most likely sGRB model requires the presence of a highly relativistic jet.  Previous work has shown that BHNS systems can produce an incipient jet\, provided that the initial magnetic field of the neutron star is allowed to extend from the interior of the star into the exterior.  We have recently performed magnetohydrodynamic simulations in full general relativity to explore the NSNS case.  We find that\, like BHNS systems\, NSNS binaries do form relativistic jets.  However\, unlike in BHNS systems\, the emergence of the jet is independent of the initial magnetic field geometry.
