Unprecedented Constraints on Gas Flows at High Redshift Using Deep JWST/NIRSpec Observations from the LyC22, EXCELS, and AURORA Surveys

Emily Kehoe, Alice E. Shapley, Adam C. Carnall +25

We investigate how low-ionization gas flows in typical star-forming galaxies at depend on galaxy intrinsic properties and viewing angle. For this analysis we use JWST/NIRS…

Massive Galaxies Form Early and Gray: Stellar Assembly and Dust Attenuation at from CAPERS

Katherine Chworowsky, Steven L. Finkelstein, Anthony J. Taylor +27

The stellar mass assembly of massive galaxies in the first few billion years of cosmic history remains a central challenge in galaxy formation. Galaxies with $M_\star \gtrsim 10^{1…

Self-Consistent Direct Method for Chemical Abundances in High-z Galaxies with JWST

Karla Z. Arellano-Córdova, J. Eduardo Méndez-Delgado, Sophia R. Flury +10

The unprecedented rest-frame UV and optical coverage provided by JWST enables simultaneous constraints on the electron density (n) and temperature (T) of ionize…

Little Red Dots: One Photometric Tag Concealing Diverse Spectroscopic Flavors of Massive Star Formation and Black Hole Activity

Pablo G. Pérez-González, Guillermo Barro, Stefano Carniani +61

We compile JWST/NIRSpec prism and MIRI data for 249 Little Red Dots (LRDs) at 2.3<z<9.3, forming a representative spectroscopic subset of NIRCam-selected LRDs. We derive a median s…

The JWST EXCELS survey: The ages and abundances of massive quiescent galaxies show that downsizing was already in place by

Ho-Hin Leung, Adam C. Carnall, Elizabeth Taylor +21

We present deep, medium-resolution m JWST/NIRSpec spectroscopy for 14 quiescent galaxies at with , obtained as part of t…

Spectroscopic confirmation of a large and luminous galaxy with weak emission lines at

Callum T. Donnan, Derek J. McLeod, Ross J. McLure +15

We present JWST/NIRSpec PRISM observations of a robust galaxy candidate at , selected from pure-parallel NIRCam imaging; PAN-z14-1. The NIRSpec spectrum allows confirmat…
