COSMOS-Web galaxy groups: Evolution of red sequence and quiescent galaxy fraction

Greta Toni, Matteo Maturi, Gianluca Castignani +33

We investigate the redshift and group richness dependence of the quiescent fraction and red-sequence (RS) parameters in COSMOS galaxy groups from z=0 to z=3.7. We analyzed the deep…

The AURORA Survey: High-Redshift Empirical Metallicity Calibrations from Electron Temperature Measurements at z=2-10

Ryan L. Sanders, Alice E. Shapley, Michael W. Topping +29

We present detections of auroral emission lines of [OIII], [OII], [SIII], and [SII] in deep JWST/NIRSpec spectroscopy for 41 star-forming galaxies at from the AURORA su…

The JWST/AURORA Survey: Multiple Balmer and Paschen Emission Lines for Individual Star-forming Galaxies at z=1.5-4.4. I. A Diversity of Nebular Attenuation Curves and Evidence for Non-Unity Dust Covering Fractions

Naveen A. Reddy, Alice E. Shapley, Ryan L. Sanders +14

We present the nebular attenuation curves and dust covering fractions for 24 redshift z=1.5-4.4 star-forming galaxies using multiple Balmer and Paschen lines from the JWST/AURORA s…

Multi-wavelength morphology and dust emission in low-redshift dwarf galaxies in COSMOS-Web with HST and JWST

D. Kakkad, I. Lazar, S. Harish +18

Low-mass or dwarf galaxies (M M) are abundant in the Universe, yet their formation and evolution remain poorly understood. Their enhanced sensitivity to fe…

COSMOS-Web: Estimating Physical Parameters of Galaxies Using Self-Organizing Maps

Fatemeh Abedini, Ghassem Gozaliasl, Akram Hasani Zonoozi +38

The COSMOS-Web survey, with its unparalleled combination of multiband data, notably, near-infrared imaging from JWST's NIRCam (F115W, F150W, F277W, and F444W), provides a transform…

The AURORA Survey: Tracing Galactic Outflows at with JWST/NIRSpec NUV Absorption Lines

Emily Kehoe, Alice E. Shapley, Ryan L. Sanders +13

We probe galactic-scale outflows in star-forming galaxies at drawn from the \textit{JWST}/NIRSpec AURORA program. For the first time, we directly compare outflow prop…
