GASTRO library II: Exploring Chemical Bimodalities in Disk Galaxies with GSE-like Mergers and Massive Star-forming Clumps
João A. S. Amarante, Chervin F. P. Laporte, Victor P. Debattista +10
We use several smoothed particle hydrodynamics+N-body models as part of the GASTRO library to study the role of high-density star-forming clumpy regions and a single merger on the…
Response of the LMC's Bar to a Recent SMC Collision and Implications for the SMC's Dark Matter Profile
Himansh Rathore, Gurtina Besla, Kathryne J. Daniel +1
The LMC's stellar bar is offset from the outer disk center, tilted from the disk plane, and does not drive gas inflows. These properties are atypical of bars in gas-rich galaxies,…
Minimum-entropy constraints on galactic potentials
Leandro Beraldo e Silva, Monica Valluri, Eugene Vasiliev +3
A tracer sample in a gravitational potential, starting from a generic initial condition, phase-mixes towards a stationary state. This evolution is accompanied by an entropy increas…
Exploring the Evolution of Massive Clumps in Simulations that Reproduce the Observed Milky Way α-element Abundance Bimodality
Bethany R. Garver, David L. Nidever, Victor P. Debattista +2
The Milky Way stellar disk has both a thin and a thick component. The thin disk is composed mostly of younger stars (8 Gyr) with a lower abundance of elements, while…
RomAndromeda: The Roman Survey of the Andromeda Halo
Arjun Dey, Joan Najita, Carrie Filion +50
As our nearest large neighbor, the Andromeda Galaxy provides a unique laboratory for investigating galaxy formation and the distribution and substructure properties of dark matter…
Early Growing Supermassive Black Holes Strengthen Bars and Boxy/Peanut Bulges
Vance Wheeler, Monica Valluri, Leandro Beraldo e Silva +2
Using N-body simulations we explore the effects of growing a supermassive black hole (SMBH) prior to or during the formation of a stellar bar. Keeping the final mass and growth rat…
