Rubin LSST DP2 unveils almost-dark galaxies in the Virgo Cluster

Minh Ngoc Le, Johan H. Knapen, Željko Ivezić +27

Galaxies with the faintest surface brightness are currently known only in the Local Group. Similar objects should exist beyond our vicinity and are crucial for understanding galaxy…

Metallicity Gradients in Modern Cosmological Simulations II: The Role of Bursty Versus Smooth Feedback at High-Redshift

Alex M. Garcia, Paul Torrey, Aniket Bhagwat +22

The distribution of gas-phase metals within galaxies encodes the impact of stellar feedback on galactic evolution. At high-redshift, when galaxies are rapidly assembling, feedback-…
