Proper Motions and Orbits of Distant Local Group Dwarf Galaxies from a combination of Gaia and Hubble Data
Paul Bennet, Ekta Patel, Sangmo Tony Sohn +12
We have determined the proper motions (PMs) of 12 dwarf galaxies in the Local Group (LG), ranging from the outer Milky Way (MW) halo to the edge of the LG. We used HST as the first…
On the co-rotation of Milky Way satellites: LMC-mass satellites induce apparent motions in outer halo tracers
Nicolas Garavito-Camargo, Adrian M. Price-Whelan, Jenna Samuel +8
Understanding the physical mechanism behind the formation of a co-rotating thin plane of satellite galaxies, like the one observed around the Milky Way (MW), has been challenging.…
A physically motivated framework to compare pair fractions of isolated low and high mass galaxies across cosmic time
Katie Chamberlain, Gurtina Besla, Ekta Patel +9
Low mass galaxy pair fractions are understudied, and it is unclear whether low mass pair fractions evolve in the same way as more massive systems over cosmic time. In the era of JW…
Machine Learning the Dark Matter Halo Mass of Milky Way-Like Systems
Elaheh Hayati, Peter Behroozi, Ekta Patel
Despite the Milky Way's proximity to us, our knowledge of its dark matter halo is fairly limited, and there is still considerable uncertainty in its halo mass. Many past techniques…
Modeling the orbital histories of satellites of Milky Way-mass galaxies: testing static host potentials against cosmological simulations
Isaiah B. Santistevan, Andrew Wetzel, Erik Tollerud +3
Understanding the evolution of satellite galaxies of the Milky Way (MW) and M31 requires modeling their orbital histories across cosmic time. Many works that model satellite orbits…
The Large Magellanic Cloud's Kiloparsec Bow Shock and its Impact on the Circumgalactic Medium
David J. Setton, Gurtina Besla, Ekta Patel +3
The interaction between the supersonic motion of the Large Magellanic Cloud (LMC) and the Circumgalactic Medium (CGM) is expected to result in a bow shock that leads the LMC's gase…
