Spatially resolved gas-phase metallicity at z~2-3 with JWST/NIRISS

Ayan Acharyya, Peter J. Watson, Benedetta Vulcani +24

Spatially resolved gas-phase metallicity maps are a crucial element in understanding the chemical evolution of galaxies. We present spatially resolved metallicity maps obtained fro…

OCEANS of Absorption: High-resolution NIRSpec Spectroscopy Reveals Diverse Balmer-line Absorption in Little Red Dots

Kelcey Davis, Madisyn Brooks, Raymond C. Simons +24

The ``Little Red Dots' (LRDs) that appeared in JWST deep field images have been the subject of significant study since their discovery. In this work, we present high-resolution fol…

A Rapid Evolution in the Observed Mbh/M* Relation at z > 3 Revealed via Spectro-photometric SED-Modeling

Ansh R. Gupta, Anthony Taylor, Emma Curtis-Lake +33

Spectroscopic observations from JWST have uncovered a plethora of active galactic nuclei (AGN) at z > 4 with black hole (BH) mass (Mbh) to stellar mass (M*) ratios significantly ab…

The NIRISS PASSAGE Spectroscopic Redshift Catalog in COSMOS

Mason S. Huberty, Kalina V. Nedkova, Zahra Sattari +34

We present the Parallel Application of Slitless Spectroscopy to Analyze Galaxy Evolution (PASSAGE) spectroscopic redshift catalog in the COSMOS field. PASSAGE is a JWST Cycle 1 Nea…

Searching Within Galaxies for the Earliest Signs of Quenching With Spatially Resolved Star Formation Histories in UVCANDELS Galaxies at z< 0.3

Charlotte Olsen, Eric Gawiser, Charlotte Welker +18

Understanding the complicated processes that regulate star formation and cause a galaxy to become quiescent is key to our comprehension of galaxy evolution. We used eight well reso…
