Implications of Broad [O III] 4364 and UV Line Emission in Two Little Red Dots at z ~ 7 - 8

Casey Papovich, Kaila Ronayne, Weida Hu +17

We present deep, NIRSpec G140M and G395M spectroscopy of Little Red Dots (LRDs) at z = 6.68 and z = 8.35. Both LRDs show broad Balmer and [O III] 4364 emission. The broad [O III…

Electron Density of Ionized Gas Outflows: Insights from the MaNGA Survey

Andrew Weldon, Casey Papovich, Justin Spilker +1

We investigate the properties of ionized gas outflows in nearby star-forming galaxies from the final Data Release of the Mapping Nearby Galaxies at Apache Point Observatory (MaNGA)…

Tracing Radio AGN-Driven Quenching in Post-Starburst Galaxies at Cosmic Noon

Pallavi Patil, Kate Rowlands, Katherine Alatalo +14

We present a radio continuum study of photometrically selected cosmic noon (0.5<z<3) post-starburst galaxies (PSBs) in the UKIDSS Deep Survey (UDS) field to assess if radio-mode Ac…

The ALPINE-CRISTAL-JWST Survey: Gas-phase abundance gradients of main sequence star-forming galaxies and their kinematics at

Lilian L. Lee, Natascha M. Förster Schreiber, Seiji Fujimoto +50

We present gas-phase radial metallicity profiles for 20 main-sequence galaxies at , primarily based on JWST NIRSpec IFU observations obtained as part of the JWST-ALPINE-CRIS…

A Morphology Catalog of Galaxies in CEERS: Evolution in the Size and Color Gradients of Galaxies Since Cosmic Dawn

Elizabeth J. McGrath, Steven L. Finkelstein, Guillermo Barro +42

We present measurements of morphological parameters from fitting 53,885 galaxies detected to a magnitude limit of F356W in the CEERS NIRCam imaging with galfit in six broad…
