Introducing the Descriptive Parametric Model: Gaseous Profiles for Galaxies, Groups, and Clusters
Benjamin D. Oppenheimer, G. Mark Voit, Yannick M. Bahé +14
We develop and present the Descriptive Parametric Model (DPM), a tool for generating profiles of gaseous halos (pressure, electron density, and metallicity) as functions of radius,…

JADES Ultra-red Flattened Objects: Morphologies and Spatial Gradients in Color and Stellar Populations
Justus L. Gibson, Erica Nelson, Christina C. Williams +20
One of the more surprising findings after the first year of JWST observations is the large number of spatially extended galaxies (ultra-red flattened objects, or UFOs) among the op…
