A census of massive eclipsing binaries in the Whirlpool Galaxy
Cheyanne Shariat, Kareem El-Badry, Maude Gull +3
We present a census of massive eclipsing binary (EB) candidates in the Whirlpool Galaxy (M51), a face-on spiral galaxy at 7.5 Mpc with . Using 34 epochs of red-optic…
Calibrating Eruptive Mass Loss in Red Supergiants with Local Group Data
Shelley J. Cheng, Charlie Conroy, Jared A. Goldberg
We calibrate a physically motivated, super-Eddington eruptive mass-loss prescription for red supergiants (RSGs) using Local Group stellar populations. Building on MESA models that…
MESA Isochrones and Stellar Tracks. II. Models with alpha-enhanced chemical composition
A Dotter, E Bauer, MJ Park +4
We update and expand the MESA Isochrones and Stellar Tracks (MIST) database to include variations in the alpha-capture elements, specifically [alpha/Fe]=-0.2, 0, +0.2, +0.4, and +0…
A Path to an All-Sky Survey with Roman
Jiwon Jesse Han, Anirudh Chiti, Kai-Feng Chen +93
A deep, space-based, all-sky near-infrared survey carried out with the Nancy Grace Roman Space Telescope would constitute a foundational astronomical infrastructure for decades to…
JWST Confirmation of a Runaway Supermassive Black Hole via its Supersonic Bow Shock
Pieter van Dokkum, Connor Jennings, Imad Pasha +6
We present JWST/NIRSpec IFU observations of a candidate runaway supermassive black hole at the tip of a 62 kpc-long linear feature at z=0.96. The JWST data show a sharp kinematic d…
Hidden mass in early galaxies revealed by bottom-heavy initial mass functions
Chloe M. Cheng, Martje Slob, Mariska Kriek +21
James Webb Space Telescope (JWST) observations have revealed that massive galaxies formed and evolved faster than predicted by galaxy formation models, with many having already ass…
Modeling the Ages and Chemical Abundances of Elliptical Galaxies
Nicole Marcelina Gountanis, David H. Weinberg, Aliza G. Beverage +3
Spectroscopic studies of elliptical galaxies show that their stellar population ages, mean metallicity, and -enhancement traced by [Mg/Fe] all increase with galaxy stellar mass…
Metals in Star-Forming Galaxies with KCWI. I. Methodology and First Results on the Abundances of Iron, Magnesium, and Oxygen
Zhuyun Zhuang, Evan N. Kirby, Charles C. Steidel +6
Understanding the chemical enrichment of different elements is crucial to gaining a complete picture of galaxy chemical evolution. In this study, we present a new sample of 46 low-…
Reconciling M/L Ratios Across Cosmic Time: a Concordance IMF for Massive Galaxies
Pieter van Dokkum, Charlie Conroy
The stellar initial mass function (IMF) is thought to be bottom-heavy in the cores of the most massive galaxies, with an excess of low mass stars compared to the Milky Way. However…
Carbon and Iron Deficiencies in Quiescent Galaxies at z=1-3 from JWST-SUSPENSE: Implications for the Formation Histories of Massive Galaxies
Aliza G. Beverage, Martje Slob, Mariska Kriek +20
We present the stellar metallicities and multi-element abundances (C, Mg, Si, Ca, Ti, Cr, and Fe) of 15 massive (log ) quiescent galaxies at z=1-3, derived fro…
The JWST-SUSPENSE Ultradeep Spectroscopic Program: Survey Overview and Star-Formation Histories of Quiescent Galaxies at 1 < z < 3
Martje Slob, Mariska Kriek, Aliza G. Beverage +19
We present an overview and first results from the Spectroscopic Ultradeep Survey Probing Extragalactic Near-infrared Stellar Emission (SUSPENSE), executed with NIRSpec on JWST. The…
The Heavy Metal Survey: The Evolution of Stellar Metallicities, Abundance Ratios, and Ages of Massive Quiescent Galaxies Since z~2
Aliza G. Beverage, Mariska Kriek, Katherine A. Suess +11
We present the elemental abundances and ages of 19 massive quiescent galaxies at and from the Keck Heavy Metal Survey. The ultra-deep LRIS and MOSFIRE spectra…
The Heavy Metal Survey: Star Formation Constraints and Dynamical Masses of 21 Massive Quiescent Galaxies at
Mariska Kriek, Aliza G. Beverage, Sedona H. Price +14
In this paper, we present the Heavy Metal Survey, which obtained ultradeep medium-resolution spectra of 21 massive quiescent galaxies at with Keck/LRIS and MOSFIRE. Wit…
Exploring Systematic Effects in the Relation Between Stellar Mass, Gas Phase Metallicity, and Star Formation Rate
O. Grace Telford, Julianne J. Dalcanton, Evan D. Skillman +1
There is evidence that the well-established mass-metallicity relation in galaxies is correlated with a third parameter: star formation rate (SFR). The strength of this correlation…
