The Star Formation History and Evolution of the Ultra-Diffuse M81 Satellite F8D1
Adam Smercina, Eric F. Bell, Benjamin F. Williams +15
We present deep HST imaging of one of the nearest ultra-diffuse galaxies (UDGs) outside of the Local Group: F8D1, a satellite of M81 known to be tidally disrupting. UDGs are an eni…

TDEs on FIRE: Illuminating the Cosmic Evolution of Tidal Disruption Rates
Rudrani Kar Chowdhury, Lixin Dai, Janet N. Y. Chang +1
Tidal disruption events have been extensively studied in the local universe, but their prevalence at high redshifts remains largely unexplored. Using the FIRE-2 cosmological zoom-i…
