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…
The imprint of clump formation at high redshift. II. The chemistry of the bulge
Victor P. Debattista, David J. Liddicott, Oscar A. Gonzalez +11
In Paper I we showed that clumps in high-redshift galaxies, having a high star formation rate density (Σ_SFR), produce disks with two tracks in the [Fe/H]-[α/Fe] chemical space, si…
Orbital support and evolution of flat profiles of bars (shoulders)
Leandro Beraldo e Silva, Victor P. Debattista, Stuart R. Anderson +4
Many barred galaxies exhibit upturns (shoulders) in their bar major-axis density profile. Simulation studies have suggested that shoulders are supported by looped orbits, occ…
