MUSE-ALMA Haloes IX: Morphologies and Stellar Properties of Gas-rich Galaxies
Arjun Karki, Varsha P. Kulkarni, Simon Weng +15
Understanding how galaxies interact with the circumgalactic medium (CGM) requires determining how galaxies morphological and stellar properties correlate with their CGM properties.…
Dancing in the dark: galactic properties trace spin swings along the cosmic web
Yohan Dubois, Christophe Pichon, Charlotte Welker +30
A large-scale hydrodynamical cosmological simulation, Horizon-AGN, is used to investigate the alignment between the spin of galaxies and the cosmic filaments above redshift 1.2. Th…
The UNCOVER Survey: A First-look HST+JWST Catalog of Galaxy Redshifts and Stellar Population Properties Spanning

The UNCOVER Survey: A first-look HST+JWST catalog of 60,000 galaxies near Abell 2744 and beyond
John R. Weaver, Sam E. Cutler, Richard Pan +41
In November 2022, the James Webb Space Telescope (JWST) returned deep near-infrared images of Abell 2744 -- a powerful lensing cluster capable of magnifying distant, incipient gala…
The SFR-radius connection: data and implications for wind strength and halo concentration
Lin Lin, S. M. Faber, David C. Koo +26

Dusty galaxies and the degeneracy between their dust distributions and the attenuation formula
Kyle Penner, Mark Dickinson, Benjamin Weiner +7
Do spatial distributions of dust grains in galaxies have typical forms, as do spatial distributions of stars? We investigate whether or not the distributions resemble uniform foreg…
Properties of Dark Matter Halos in Disk Galaxies
Roelof S. de Jong, Susan Kassin, Eric F. Bell +1
We present a simple technique to estimate mass-to-light (M/L) ratios of stellar populations based on two broadband photometry measurements, i.e. a color-M/L relation. We apply the…
JWST reveals a possible galaxy merger in triply-lensed MACS0647JD
