Untangling Magellanic Streams
Dennis Zaritsky, Vedant Chandra, Charlie Conroy +3
The Magellanic Stream (MS) has long been known to contain multiple H I strands and corresponding stellar populations are beginning to be discovered. Combining a sample of 17 stars…
-MC: Self-consistent -enhanced stellar population models covering a wide range of age, metallicity, and wavelength
Minjung Park, Charlie Conroy, Benjamin D. Johnson +3
We present new stellar population models, -MC, self-consistently taking into account non-solar abundances for both isochrones and stellar spectra. The -MC models…
Rising from the Ashes II: The Bar-driven Abundance Bimodality of the Milky Way
Angus Beane, James Johnson, Vadim Semenov +3
The Milky Way hosts at least two modes in its present day distribution of Fe and alpha-elements. The exact cause of this bimodality is disputed, but one class of explanations invol…
From UV-bright Galaxies to Early Disks: the Importance of Turbulent Star Formation in the Early Universe
Vadim A. Semenov, Charlie Conroy, Lars Hernquist
Bursty star formation at early times can explain the surprising abundance of early UV-bright galaxies revealed by JWST but can also be a reason for the delayed formation of galacti…
The Rapid Formation of the Metal Poor Milky Way
Turner Woody, Charlie Conroy, Phillip Cargile +6
Our understanding of the assembly timeline of the Milky Way has been transforming along with the dramatic increase in astrometric and spectroscopic data available over the past sev…
How Early Could the Milky Way's Disk Form?
Vadim A. Semenov, Charlie Conroy, Aaron Smith +2
We investigate early, , galaxy formation in a cosmological zoom-in simulation of a close, early-forming Milky Way (MW) analog extracted from TNG50 simulation and resimulated…
Segue 2 Recently Collided with the Cetus-Palca Stream: New Opportunities to Constrain Dark Matter in an Ultra-Faint Dwarf
Hayden R. Foote, Gurtina Besla, Nicolás Garavito-Camargo +7
Stellar streams in the Milky Way are promising detectors of low-mass dark matter (DM) subhalos predicted by CDM. Passing subhalos induce perturbations in streams that indicate t…
Our Halo of Ice and Fire: Strong Kinematic Asymmetries in the Galactic Halo
Jiwon Jesse Han, Charlie Conroy, Dennis Zaritsky +4
The kinematics of the stellar halo hold important clues to the assembly history and mass distribution of the Galaxy. In this study, we map the kinematics of stars across the Galact…
AGN Feedback in Quiescent Galaxies at Cosmic Noon Traced by Ionized Gas Emission
Letizia Bugiani, Sirio Belli, Minjung Park +17
We analyze ionized gas emission lines in deep rest-frame optical spectra of 16 quiescent galaxies at redshift observed with JWST/NIRSpec by the Blue Jay survey. Robust…
On the Origin of High-velocity Clouds in the Galaxy
Scott Lucchini, Jiwon Jesse Han, Lars Hernquist +1
The origin of our Galaxy's high-velocity clouds (HVCs) remains a mystery after many decades of effort. In this paper, we use the TNG50 simulation of the IllustrisTNG project to ide…
All-Sky Kinematics of the Distant Halo: The Reflex Response to the LMC
Vedant Chandra, Rohan P. Naidu, Charlie Conroy +11
The infall of the Large Magellanic Cloud (LMC) is predicted to displace the inner Milky Way (MW), imprinting an apparent 'reflex motion' on the observed velocities of distant halo…
A Model for Eruptive Mass Loss in Massive Stars
Shelley J. Cheng, Jared A. Goldberg, Matteo Cantiello +3
Eruptive mass loss in massive stars is known to occur, but the mechanism(s) are not yet well-understood. One proposed physical explanation appeals to opacity-driven super-Eddington…
Widespread rapid quenching at cosmic noon revealed by JWST deep spectroscopy
Minjung Park, Sirio Belli, Charlie Conroy +16
Massive quiescent galaxies in the young universe are expected to be quenched rapidly, but it is unclear whether they all experience starbursts before quenching and what physical me…
Anatomy of an ionized bubble: NIRCam grism spectroscopy of the double-peaked Lyman- emitter COLA1 and its environment
Alberto Torralba-Torregrosa, Jorryt Matthee, Rohan P. Naidu +10
The increasingly neutral intergalactic gas at impacts the Lyman- flux observed from galaxies. One luminous galaxy, COLA1, stands out because of its unique double-peaked Ly…
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…
