Cluster vs Field: Clear Evidence for a Morphology-Density Relation in All Environments at

Westley Brown, Adam Muzzin, Jasleen Matharu +6

We explore the relationship between galaxy structure, stellar mass, and local galaxy density in three SpARCS clusters at and compare with field galaxies from the 3D-HST…

UV slopes of Starforming Galaxies in Strong Lensing fields at the Epoch of Reionization with JWST

Giordano Felicioni, Maruša Bradač, Yoshihisa Asada +20

UV slopes () are a powerful diagnostics for galaxies at the Epoch of Reionization, tracing star formation, ISM ionization, and the escape fraction of ionizing photons…

Euclid Quick Data Release (Q1): Hunting for luminous z > 6 galaxies in the Euclid Deep Fields -- forecasts and first bright detections

Euclid Collaboration, N. Allen, P. A. Oesch +309

The evolution of the rest-frame ultraviolet luminosity function (UV LF) is a powerful probe of early star formation and stellar mass build-up. At z > 6, its bright end (MUV < -21)…

A first look at a complete view of spatially resolved star formation at 1<z<1.8 with JWST NGDEEP+FRESCO slitless spectroscopy

Jasleen Matharu, Lu Shen, Irene Shivaei +15

[abridged] The previously inaccessible star formation tracer Pa can now be spatially resolved by JWST NIRCam slitless spectroscopy in distant galaxies up to cosmic noon. In the…

DAWN JWST Archive: Morphology from profile fitting of over 340 000 galaxies in major fields

Aurélien Genin, Marko Shuntov, Gabe Brammer +7

To better understand how galaxies assemble their structure and evolve over cosmic time, we present a new catalog of morphological measurements for over 340,000 sources spanning $0…

CANUCS/Technicolor Data Release 1: Imaging, Photometry, Slit Spectroscopy, and Stellar Population Parameters

Ghassan T. E. Sarrouh, Yoshihisa Asada, Nicholas S. Martis +44

We present the first data release of the CAnadian NIRISS Unbiased Cluster Survey (CANUCS), a JWST Cycle 1 GTO program targeting 5 lensing clusters and flanking fields in parallel (…
