The Merger-Driven Formation of Classical Low Surface Brightness Galaxies in Romulus25
Anna C. Wright, Alyson M. Brooks, Michael Tremmel +3
We use the Romulus25 cosmological simulation volume to study a large sample of late-type gas-rich galaxies with low central surface brightnesses known as classical low surface brig…
Survivors and Zombies: The Quenching and Disruption of Satellites around Milky Way Analogs
Debosmita Pathak, Charlotte R. Christensen, Alyson M. Brooks +3
It is necessary to understand the full accretion history of the Milky Way in order to contextualize the properties of observed Milky Way satellite galaxies and the stellar halo. Th…
Are Gas-rich Ultra-diffuse Galaxies and Field Dwarfs Distinct?
Khadeejah Motiwala, Ananthan Karunakaran, Kristine Spekkens +5
We explore the differences in gas-rich field Ultra-Diffuse Galaxies (UDGs) and classical dwarf galaxies using an extensive atomic gas (HI) follow-up survey of optically-selected UD…
Figuring Out Gas & Galaxies In Enzo (FOGGIE) VIII: Complex and Stochastic Metallicity Gradients at z > 2
Ayan Acharyya, Molly S. Peeples, Jason Tumlinson +7
Gas-phase metallicity gradients are a crucial element in understanding the chemical evolution of galaxies. We use the FOGGIE simulations to study the metallicity gradients ($\nabla…
Figuring Out Gas & Galaxies In Enzo (FOGGIE) VII: The (Dis)Assembly of Stellar Halos
Anna C. Wright, Jason Tumlinson, Molly S. Peeples +7
Over the next decade, the astronomical community will be commissioning multiple wide-field observatories well-suited for studying stellar halos in both integrated light and resolve…
Figuring Out Gas & Galaxies In Enzo (FOGGIE) VI: The Circumgalactic Medium of Galaxies is Supported in an Emergent, Non-Hydrostatic Equilibrium
Cassandra Lochhaas, Jason Tumlinson, Molly S. Peeples +9
The circumgalactic medium (CGM) is often assumed to exist in or near hydrostatic equilibrium with the regulation of accretion and the effects of feedback treated as perturbations t…
Snowmass2021 Cosmic Frontier White Paper: Cosmological Simulations for Dark Matter Physics
Arka Banerjee, Kimberly K. Boddy, Francis-Yan Cyr-Racine +15
Over the past several decades, unexpected astronomical discoveries have been fueling a new wave of particle model building and are inspiring the next generation of ever-more-sophis…
What's in a name? Quantifying the interplay between the Definition, Orientation, and Shape of Ultra-diffuse Galaxies Using the Romulus Simulations
Jordan D. Van Nest, F. Munshi, A. C. Wright +4
We explore populations of ultra-diffuse galaxies (UDGs) in isolated, satellite, and cluster environments using the Romulus25 and RomulusC simulations, including how the populations…
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…
Black Hole Growth and Feedback in Isolated Romulus25 Dwarf Galaxies
Ray Sharma, Alyson Brooks, Rachel S. Somerville +4
We investigate the effects of massive black hole growth on the structural evolution of dwarf galaxies within the Romulus25 cosmological hydrodynamical simulation. We study a sample…
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…
