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…
Hidden mass in early galaxies revealed by bottom-heavy initial mass functions
Chloe M. Cheng, Martje Slob, Mariska Kriek +23
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…
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…
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…
