Galaxy mergers and disk angular momentum evolution: stellar halos as a critical test
Eric F. Bell, Richard D'Souza, Monica Valluri +1
We investigate the role of hierarchical assembly in the angular momentum (AM) evolution of galaxies using a sample of 471 Milky Way-mass galaxies from the TNG-50 simulation. While…
Exploring the interaction between the MW and LMC with a large sample of blue horizontal branch stars from the DESI survey
Amanda Byström, Sergey E. Koposov, Sophia Lilleengen +42
The Large Magellanic Cloud (LMC) is a Milky Way (MW) satellite that is massive enough to gravitationally attract the MW disc and inner halo, causing significant motion of the inner…
Stellar bars form dark matter counterparts in TNG50
Neil Ash, Monica Valluri, Yingtian Chen +1
Dark matter (DM) bars that shadow stellar bars have been previously shown to form in idealized simulations of isolated disk galaxies. Here, we show that DM bars commonly occur in b…
GD-1 Stellar Stream and Cocoon in the DESI Early Data Release
Monica Valluri, Parker Fagrelius, Sergey. E. Koposov +49
We present 115 new spectroscopically identified members of the GD-1 tidal stream observed with the 5000-fiber Dark Energy Spectroscopic Instrument (DESI). We confirm the existence…
