Carbon-Enhanced Dwarf Stars Are Predominantly a Halo Population

Jay Farihi, Jason L. Sanders, Sophia Lilleengen +2

This paper reports a Galactic kinematical and dynamical analysis of 1003 main-sequence carbon stars. The sample is drawn from the Sloan Digital Sky Survey, and cross-matched with G…

Nearby stellar substructures in the Galactic halo from DESI Milky Way Survey Year 1 Data Release

Bokyoung Kim, Sergey E. Koposov, Ting S. Li +41

We report five nearby ( kpc) stellar substructures in the Galactic halo from a subset of 138,661 stars in the Dark Energy Spectroscopic Instrument (DESI) Mi…

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…

LMC Calls, Milky Way Halo Answers: Disentangling the Effects of the MW--LMC Interaction on Stellar Stream Populations

Richard A. N. Brooks, Nicolás Garavito-Camargo, Kathryn V. Johnston +3

The infall of the LMC into the Milky Way (MW) has dynamical implications throughout the MW's dark matter halo. We study the impact of this merger on the statistical properties of p…

Accreted Globular Clusters in External Galaxies: Why Adaptive Dynamics is not the Solution

Sophia Lilleengen, Wilma H. Trick, Glenn van de Ven

Many astrophysical and galaxy-scale cosmological problems require a well determined gravitational potential which is often modeled by observers under strong assumptions. Globular c…
