Wide binaries in an ultra-faint dwarf galaxy: discovery, population modeling, and a nail in the coffin of primordial black hole dark matter
Cheyanne Shariat, Kareem El-Badry, Mario Gennaro +24
We report the discovery and characterization of a wide binary population in the ultrafaint dwarf galaxy Boötes I using deep JWST/NIRCam imaging. Our sample consists of 52 candidate…
The Orbits of Isolated Dwarfs in the Local Group from New 3D Kinematics: Constraints on First Infall, Backsplash, and Quenching Mechanisms
Paul Bennet, Ekta Patel, Sangmo Tony Sohn +8
It is commonly supposed that quenched field dwarfs near the edge of the Local Group (LG) are backsplash galaxies, having previously orbited within the Milky Way (MW) or M31's viria…
Clues to inside-out quenching in quiescent galaxies at : Age, Fe-, and Mg-abundance gradients from JWST-SUSPENSE
Chloe M. Cheng, Martje Slob, Mariska Kriek +16
[Abridged] Spatially resolved stellar populations of massive quiescent galaxies at cosmic noon provide powerful insights into quenching and assembly mechanisms. Previous photometri…
Discovery of SiC and Iron Dust Around AGB Stars in the very Metal-Poor Sextans A Dwarf Galaxy with JWST: Implications for Dust Production at High Redshift
M. L. Boyer, G. C. Sloan, A. Nanni +23
Low-resolution infrared spectroscopy from JWST confirms the presence of SiC and likely metallic iron dust around asymptotic giant branch (AGB) stars in the Sextans A dwarf galaxy,…
The Star Formation History and Evolution of the Ultra-Diffuse M81 Satellite F8D1
Adam Smercina, Eric F. Bell, Benjamin F. Williams +15
We present deep HST imaging of one of the nearest ultra-diffuse galaxies (UDGs) outside of the Local Group: F8D1, a satellite of M81 known to be tidally disrupting. UDGs are an eni…
Fast Rotators at Cosmic Noon: Stellar Kinematics for 15 Quiescent Galaxies from JWST-SUSPENSE
Martje Slob, Mariska Kriek, Anna de Graaff +14
We present spatially-resolved stellar kinematics of 15 massive () quiescent galaxies at from the JWST-SUSPENSE program. This is the larg…
