The observable properties of galaxy accretion events in Milky Way-like galaxies in the FIRE-2 cosmological simulations
Danny Horta, Emily C. Cunningham, Robyn E. Sanderson +7
In the -Cold Dark Matter model of the Universe, galaxies form in part through accreting satellite systems. Previous work have built an understanding of the signatures of these p…
High-Resolution Chemical Abundances of the Nyx Stream
Shuyu Wang, Lina Necib, Alexander P. Ji +5
Nyx is a nearby, prograde, and high-eccentricity stellar stream physically contained in the thick disk but with an unknown origin. Nyx could be the remnant of a disrupted dwarf gal…
Uncovering dark matter density profiles in dwarf galaxies with graph neural networks
Tri Nguyen, Siddharth Mishra-Sharma, Reuel Williams +1
Dwarf galaxies are small, dark matter-dominated galaxies, some of which are embedded within the Milky Way. Their lack of baryonic matter (e.g., stars and gas) makes them perfect te…
Streams on FIRE: Populations of Detectable Stellar Streams in the Milky Way and FIRE
Nora Shipp, Nondh Panithanpaisal, Lina Necib +18
We present the first detailed study comparing the populations of stellar streams in cosmological simulations to observed Milky Way dwarf galaxy streams. In particular, we compare s…
Robust Clustering of the Local Milky Way Stellar Kinematic Substructures with Gaia eDR3
Xiaowei Ou, Lina Necib, Anna Frebel
We apply the clustering algorithm HDBSCAN on the Gaia early third data release astrometry combined with the Gaia second data release radial velocity measurements of almost 5.5 mill…
Dissipative Dark Matter on FIRE: II. Observational signatures and constraints from local dwarf galaxies
Xuejian Shen, Philip F. Hopkins, Lina Necib +3
We analyze the first set of cosmological baryonic zoom-in simulations of galaxies in dissipative self-interacting dark matter (dSIDM). The simulations utilize the FIRE-2 galaxy for…
The Chemical Composition of Extreme-Velocity Stars
Henrique Reggiani, Alexander P. Ji, Kevin C. Schlaufman +5
Little is known about the origin of the fastest stars in the Galaxy. Our understanding of the Milky Way and surrounding dwarf galaxies chemical evolution history allows us to use t…
Snowmass2021 Cosmic Frontier White Paper: Cosmological Simulations for Dark Matter Physics
Arka Banerjee, Kimberly K. Boddy, Francis-Yan Cyr-Racine +15
Over the past several decades, unexpected astronomical discoveries have been fueling a new wave of particle model building and are inspiring the next generation of ever-more-sophis…
Snowmass2021 Cosmic Frontier: Synergies between dark matter searches and multiwavelength/multimessenger astrophysics
Shin'ichiro Ando, Sebastian Baum, Michael Boylan-Kolchin +23
This whitepaper focuses on the astrophysical systematics which are encountered in dark matter searches. Oftentimes in indirect and also in direct dark matter searches, astrophysica…
FIRE-3: Updated Stellar Evolution Models, Yields, & Microphysics and Fitting Functions for Applications in Galaxy Simulations
Philip F. Hopkins, Andrew Wetzel, Coral Wheeler +18
Increasingly, uncertainties in predictions from galaxy formation simulations (at sub-Milky Way masses) are dominated by uncertainties in stellar evolution inputs. In this paper, we…
