Star Formation Histories from SEDs and CMDs Agree: Evidence for Synchronized Star Formation in Local Volume Dwarf Galaxies over the Past 3 Gyr
Charlotte Olsen, Eric Gawiser, Kartheik Iyer +6
Star Formation Histories (SFHs) reveal physical processes that influence how galaxies form their stellar mass. We compare the SFHs of a sample of 36 nearby (D 4 Mpc) dwarf g…
An Excess of Globular Clusters in UDGs Formed Through Tidal Heating
Timothy Carleton, Yicheng Guo, Ferah Munshi +2
To investigate the origin of elevated globular cluster abundances observed around Ultra-Diffuse Galaxies (UDGs), we simulate globular cluster populations hosted by UDGs formed thro…
The Formation of Isolated Ultra-Diffuse Galaxies in Romulus25
Anna C. Wright, Michael Tremmel, Alyson M. Brooks +4
We use the \textsc{Romulus25} cosmological simulation volume to identify the largest-ever simulated sample of {\it field} ultra-diffuse galaxies (UDGs). At , we find that isol…
The Formation of Ultra-Diffuse Galaxies in the RomulusC Galaxy Cluster Simulation
Michael Tremmel, Anna C. Wright, Alyson M. Brooks +3
We study the origins of 122 ultra-diffuse galaxies (UDGs) in the {\sc RomulusC} zoom-in cosmological simulation of a galaxy cluster (M M), one…
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…
