From Extreme Binary Stars to Self-Driving Cars
Dr. Tony Rodriguez
Data Scientist, Waymo LLC (formerly Harvard CfA)

Compact objects -- white dwarfs (WDs), neutron stars, and black holes -- are laboratories for studying extreme physics under conditions unable to be replicated on Earth. When located in binaries, it becomes possible to measure properties of compact objects such as magnetic field strength, temperature, and the effects of mass transfer from a companion. In this talk, I will describe recent advancements in our understanding of WD magnetism.

Solving Atomic Structures of Molecules and Nanoclusters Using Superfluid Helium Droplet Cooling and Laser Alignment
Wei Kong
Department Head & Professor, Department of Chemistry - Oregon State University

We are building a prototype experimental apparatus to determine the atomic structures of molecules and nanoclusters using electron diffraction. We use superfluid helium droplets for cooling, thereby achieving effective field-induced orientation and alignment of the sample species. Electron diffraction patterns from the chosen orientation can then be accumulated until a satisfactory signal-to-noise ratio can be obtained.

Better Together: Combining the Strengths of Rubin, Euclid, and Roman for Time-domain Science and Cosmology
Charlotte Ward
Assistant Professor, Department of Astronomy and Astrophysics in the Eberly College of Sciences at Penn State

We have entered an exciting decade for survey science, with space-based surveys such as Euclid and Roman and ground-based surveys such as Rubin Observatory's Legacy Survey of Space and Time (LSST) providing overlapping imaging datasets across the optical and IR. LSST will identify thousands of tidal disruption events (TDEs) and millions of AGN and supernovae – including hundreds of gravitationally lensed supernovae (gLSNe) from which we can measure the Hubble Constant.
