SUMMARY:Physics Colloquium: Ryan Trainor
DESCRIPTION:“Feedback in Dwarf Galaxies at z>2”\nRyan Trainor\, Franklin & Marshall College \nHigh-redshift dwarf galaxies (L << L*) are high-priority science targets for both JWST and current surveys: these galaxies appear extremely sensitive to stellar feedback\, and they are likely to dominate the ionizing photon budget during the epoch of reionization (EoR).  However\, the physical properties of the stellar populations and interstellar media in these galaxies are difficult to constrain because of their extremely faint continuum and line emission. \nI will describe our on-going work to spectroscopically characterize low-luminosity galaxies at high redshifts using two complementary methods: stacked spectra\, which reveal average galaxy properties\, and lensed spectra of individual galaxies\, which will constrain the variability of faint galaxy populations in the early Universe.  Together\, these surveys will produce powerful constraints on the role of faint galaxies at all redshifts and on the observability of such galaxies during the EoR.

SUMMARY:Physics Colloquium: Laura Chomiuk
DESCRIPTION:“Rethinking the Fundamentals of Classical Nova Explosions”\nLaura Chomiuk\, Michigan State University \nOver the past few years\, a revolution has been taking place in our understanding of classical novae\, largely driven by the discovery of GeV gamma-rays emanating from these garden-variety explosions. These gamma-rays hint that shocks are energetically important—perhaps even dominant—in novae. \nI will present our burgeoning understanding of shocks in novae\, from both multi-wavelength observational and theoretical perspectives. I will also illustrate how novae can be used as testbeds to understand other shock-powered explosions\, like stellar mergers and super-luminous supernovae.
