The Impact of Simulation Resolution on Dwarf Galaxy Stellar Stream Populations in FIRE
Yasmine J. Meziani, Nondh Panithanpaisal, Robyn E. Sanderson +4
Cosmological simulations allow us to study galaxy-progenitor stream populations, allowing comparisons with observations to constrain galaxy formation physics. Previous work found t…
Predicting the Kinematics of the Cold Circumgalactic Medium from its Morphology using Convolutional Neural Networks
Connor Jennings, Earl P. Bellinger, Imad Pasha +2
We present a novel approach to predicting plane-of-sky velocities of cold gas clouds in the circumgalactic medium (CGM) of galaxies. The method uses a convolutional neural network…
Resolving galaxy formation in the early Universe with BonFIRE and CampFIRE
Jenna Samuel, Michael Boylan-Kolchin, Robert Feldmann +16
The abundance and rapid growth of galaxies at cosmic dawn revealed by the James Webb Space Telescope challenges models of galaxy formation, motivating new simulations to uncover th…
From protogalaxy through thick and thin: Why did the Milky Way evolve in three kinematic phases?
Olti Myrtaj, James S. Bullock, Michael Boylan-Kolchin +9
APOGEE and Gaia data suggest the Milky Way's kinematic structure evolved through three distinct phases: a disordered protogalaxy, which ``spun up'' into a thick stellar disk, and t…
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…
FORGE'd in the Early Universe: The Effect of Protostellar Outflows on Pop III Accretion
Yasmine J. Meziani, Philip F. Hopkins, Michael Y. Grudić +3
We present a cosmological zoom-in radiation magneto-hydrodynamic (RMHD) simulation, using FORGE'd in FIRE, that follows the formation, growth, and evolution of a single metal-free…
Igniting galaxy formation in the post-reionization universe
Jorge Moreno, Coral Wheeler, Francisco J. Mercado +9
It is widely believed that the ultraviolet background produced during the epoch of reionization conspires against the formation of low-mass galaxies. Indeed, this mechanism is ofte…
The quenched fraction of satellites around simulated Milky Way-mass galaxies
Francisco J. Mercado, Devontae C. Baxter, M. Katy Rodriguez Wimberly +7
We compare satellite quenched fractions across three cosmological simulation suites (FIREbox, the FIRE-2 zoom-ins, and IllustrisTNG50) and observational datasets from SAGA, ELVES,…
Rise of the forsaken relics: connecting present-day stellar streams and phase-mixed galaxies to the Epoch of Reionization
Aritra Kundu, Robyn Sanderson, Adam Lidz +6
The `near-far' approach to studying reionization leverages the star formation histories of the Milky Way (MW) or Local Group (LG) galaxies, derived from resolved photometry, to inf…
Second public data release of the FIRE-2 cosmological zoom-in simulations of galaxy formation
Andrew Wetzel, Jenna Samuel, Pratik J. Gandhi +34
We describe the second data release (DR2) of the FIRE-2 cosmological zoom-in simulations of galaxy formation, from the Feedback In Realistic Environments (FIRE) project, available…
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…
Stellar Mass Calibrations for Local Low-Mass Galaxies
Mithi A. C. de los Reyes, Yasmeen Asali, Risa Wechsler +10
The stellar masses of galaxies are measured using integrated light via several methods -- however, few of these methods were designed for low-mass ($M_{\star}\lesssim10^{8}\rm{M_{\…
Testing the near-far connection with FIRE simulations: inferring the stellar mass function of the proto-Local Group at z > 6 using the fossil record of present-day galaxies
Pratik J. Gandhi, Andrew Wetzel, Michael Boylan-Kolchin +6
The shape of the low-mass (faint) end of the galaxy stellar mass function (SMF) or ultraviolet luminosity function (UVLF) at z > 6 is an open question for understanding which galax…
The proto-galaxy of Milky Way-mass haloes in the FIRE simulations
Danny Horta, Emily C. Cunningham, Robyn Sanderson +9
Observational studies are finding stars believed to be relics of the earliest stages of hierarchical mass assembly of the Milky Way (i.e., proto-Galaxy). In this work, we contextua…
First Detections of Exop(lan)ets: Observations and Follow-Ups of the Floofiest Transits on Zoom
Sabina Sagynbayeva, Briley L. Lewis, Graham M. Doskoch +16
With the proliferation of online Zoom meetings as a means of doing science in the 2020s, astronomers have made new and unexpected Target of Opportunity (ToO) observations. Chief am…
Exploring metallicity-dependent rates of Type Ia supernovae and their impact on galaxy formation
Pratik. J. Gandhi, Andrew Wetzel, Philip F. Hopkins +3
Type Ia supernovae play a critical role in stellar feedback and elemental enrichment in galaxies. Recent transient surveys like the All-Sky Automated Survey for Supernova (ASAS-SN)…
RELICS-DP7: Spectroscopic Confirmation of a Dichromatic Primeval Galaxy at z ~ 7
Debora Pelliccia, Victoria Strait, Brian C. Lemaux +12
We report the discovery of a spectroscopically-confirmed strong Lyman- emitter at , observed as part of the Reionization Cluster Lensing Survey (RELICS). This…
