Stars made in outflows may populate the stellar halo of the Milky Way
Sijie Yu, James S. Bullock, Andrew Wetzel +8
We study stellar-halo formation using six Milky Way-mass galaxies in FIRE-2 cosmological zoom simulations. We find that of the outer ( kpc) stellar halo in each sy…
Astro2020 APC White Paper: The Early Career Perspective on the Coming Decade, Astrophysics Career Paths, and the Decadal Survey Process
Emily Moravec, Ian Czekala, Kate Follette +53
In response to the need for the Astro2020 Decadal Survey to explicitly engage early career astronomers, the National Academies of Sciences, Engineering, and Medicine hosted the Ear…
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…
The Implications of Local Fluctuations in the Galactic Midplane for Dynamical Analysis in the Gaia Era
Angus Beane, Robyn E. Sanderson, Melissa K. Ness +6
Orbital properties of stars, computed from their six-dimensional phase space measurements and an assumed Galactic potential, are used to understand the structure and evolution of t…
