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…
