Chasing Accreted Structures within Gaia DR2 using Deep Learning
Lina Necib, Bryan Ostdiek, Mariangela Lisanti +3
In previous work, we developed a deep neural network classifier that only relies on phase-space information to obtain a catalog of accreted stars based on the second data release o…
Evidence for a Vast Prograde Stellar Stream in the Solar Vicinity
Lina Necib, Bryan Ostdiek, Mariangela Lisanti +6
Massive dwarf galaxies that merge with the Milky Way on prograde orbits can be dragged into the disk plane before being completely disrupted. Such mergers can contribute to an accr…
Cataloging Accreted Stars within Gaia DR2 using Deep Learning
Bryan Ostdiek, Lina Necib, Timothy Cohen +6
The goal of this study is to present the development of a machine learning based approach that utilizes phase space alone to separate the Gaia DR2 stars into two categories: those…
Predicting the LISA white dwarf binary population in the Milky Way with cosmological simulations
Astrid Lamberts, Sarah Blunt, Tyson Littenberg +3
Short-period (P<1 hour) white dwarf binaries will be the most numerous sources for the space-based gravitational wave detector LISA. Based on thousands of resolved systems, we will…
Characterizing the Infall Times and Quenching Timescales of Milky Way Satellites with Proper Motions
Sean P. Fillingham, Michael C. Cooper, Tyler Kelley +6
Observations of low-mass satellite galaxies in the nearby Universe point towards a strong dichotomy in their star-forming properties relative to systems with similar mass in the fi…
But What About... Cosmic Rays, Magnetic Fields, Conduction, & Viscosity in Galaxy Formation
Philip F. Hopkins, T. K. Chan, Shea Garrison-Kimmel +6
We present a suite of high-resolution cosmological simulations, using the FIRE-2 feedback physics together with explicit treatment of magnetic fields, anisotropic conduction and vi…
A profile in FIRE: resolving the radial distributions of satellite galaxies in the Local Group with simulations
Jenna Samuel, Andrew Wetzel, Erik Tollerud +9
While many tensions between Local Group (LG) satellite galaxies and LCDM cosmology have been alleviated through recent cosmological simulations, the spatial distribution of satelli…
Star formation histories of dwarf galaxies in the FIRE simulations: dependence on mass and Local Group environment
Shea Garrison-Kimmel, Andrew Wetzel, Phillip F. Hopkins +13
We study star formation histories (SFHs) of dwarf galaxies (stellar mass ) from FIRE-2 cosmological zoom-in simulations. We compare dwarf…
