Roll of the Dice: A Stochastically Sampled IMF Alters the Stellar Content of Simulated Dwarf Galaxies
Elaad Applebaum, Alyson M. Brooks, Thomas R. Quinn +1
Cosmological simulations are reaching the resolution necessary to study ultra-faint dwarf galaxies. Observations indicate that in small populations, the stellar initial mass functi…
Dancing in the Dark: Uncertainty in ultra-faint dwarf galaxy predictions from cosmological simulations
Ferah Munshi, Alyson M. Brooks, Charlotte Christensen +4
The existence of ultra-faint dwarf (UFD) galaxies highlights the need to push our theoretical understanding of galaxies to extremely low mass. We examine the formation of UFDs by t…
Tracing Outflowing Metals in Simulations of Dwarf and Spiral Galaxies
Charlotte R. Christensen, Romeel Dave, Alyson Brooks +2
We analyze the metal accumulation in dwarf and spiral galaxies by following the history of metal enrichment and outflows in a suite of twenty high-resolution simulated galaxies. Th…
Multimessenger Signatures of Massive Black Holes in Dwarf Galaxies
Jillian Bellovary, Colleen Cleary, Ferah Munshi +4
Recent discoveries of massive black holes (MBHs) in dwarf galaxies suggest that they may have a more common presence than once thought. Systematic searches are revealing more candi…
Reignition of Star Formation in Dwarf Galaxies
Anna C. Wright, Alyson M. Brooks, Daniel R. Weisz +1
The Local Group hosts a number of star-forming dwarf galaxies that show evidence of periods of little to no star formation. We use a suite of cosmological simulations to study how…
