Beyond Cloud-9: The case for discovering more HI-rich failed halos
Jorge Moreno, Coral Wheeler, Francisco J. Mercado +8
HI-rich starless halos, should they exist, hold great promise for elucidating dark matter halo structure. Yet realizing this potential demands reliable theoretical predictions for…
How invisible stellar halos bias our understanding of ultra-faint galaxies
Coral Wheeler, Jorge Moreno, M. Katy Rodriguez Wimberly +6
We explore how a realistic surface brightness detection limit of mag arcsec for stars at the edges of ultra-faint galaxies affects our ability to infer th…
Bloodhound Unleashed: Particle-based Substructure Tracking for Cosmological Simulations
Hyunsu Kong, Michael Boylan-Kolchin, James S. Bullock
Modern studies of galaxy formation rely heavily on numerical simulations, which in turn require tools to identify and track self-bound structures in stars and dark matter. In this…
Central densities of dark matter halos in FIRE-2 simulations of low-mass galaxies with cold dark matter and self-interacting dark matter
Maria C. Straight, Michael Boylan-Kolchin, James S. Bullock +6
We investigate the central density structure of dark matter halos in cold dark matter (CDM) and self-interacting dark matter (SIDM) models using simulations that are part of the Fe…
Effects of galactic environment on size and dark matter content in low-mass galaxies
Francisco J. Mercado, Jorge Moreno, Robert Feldmann +8
We utilize the cosmological volume simulation, FIREbox, to investigate how a galaxy's environment influences its size and dark matter content. Our study focuses on approximately 1,…
Confronting the Diversity Problem: The Limits of Galaxy Rotation Curves as a tool to Understand Dark Matter Profiles
Isabel S. Sands, Philip F. Hopkins, Xuejian Shen +9
While galaxy rotation curves provide one of the most powerful methods for measuring dark matter profiles in the inner regions of rotation-supported galaxies, at the dwarf scale the…
Sliding into DM: Determining the local dark matter density and speed distribution using only the local circular speed of the Galaxy
Patrick G. Staudt, James S. Bullock, Michael Boylan-Kolchin +3
We use FIRE-2 zoom simulations of Milky Way size disk galaxies to derive easy-to-use relationships between the observed circular speed of the Galaxy at the Solar location, $v_\math…
The JWST Resolved Stellar Populations Early Release Science Program V. DOLPHOT Stellar Photometry for NIRCam and NIRISS
Daniel R. Weisz, Andrew E. Dolphin, Alessandro Savino +38
We present NIRCam and NIRISS modules for DOLPHOT, a widely-used crowded field stellar photometry package. We describe details of the modules including pixel masking, astrometric al…
Hooks & Bends in the Radial Acceleration Relation: Discriminatory Tests for Dark Matter and MOND
Francisco J. Mercado, James S. Bullock, Jorge Moreno +5
The Radial Acceleration Relation (RAR) connects the total gravitational acceleration of a galaxy at a given radius, , with that accounted for by baryons at the same…
A dark matter profile to model diverse feedback-induced core sizes of CDM haloes
Alexandres Lazar, James S. Bullock, Michael Boylan-Kolchin +11
We analyze the cold dark matter density profiles of 54 galaxy halos simulated with FIRE-2 galaxy formation physics, each resolved within of the halo virial radius. These ha…
Dark and luminous satellites of LMC-mass galaxies in the FIRE simulations
Ethan D. Jahn, Laura V. Sales, Andrew Wetzel +5
Within CDM, dwarf galaxies like the Large Magellanic Cloud (LMC) are expected to host numerous dark matter subhalos, several of which should host faint dwarf companions. Recent…
The Dark Disk of the Milky Way
Chris W. Purcell, James S. Bullock, Manoj Kaplinghat
Massive satellite accretions onto early galactic disks can lead to the deposition of dark matter in disk-like configurations that co-rotate with the galaxy. This phenomenon has pot…
