Early Results from GLASS-JWST. XXVI. Spatially Resolved Star Formation and Balmer Decrements at from NIRISS Slitless Spectroscopy
Pengfei Ren, Xin Wang, Yuxuan Pang +10
Using JWST/NIRISS slitless spectroscopy, we present spatially resolved Balmer decrement measurements for 79 galaxies at , which are gravitationally lensed by the for…
Lyman-alpha emission at the end of reionization: line strengths and profiles from MMT and JWST observations at z~5-6
Gonzalo Prieto-Lyon, Charlotte A. Mason, Victoria Strait +8
With JWST, it is now possible to use Lyman-Alpha (Ly) emission from galaxies beyond z>8 to trace neutral hydrogen in the intergalactic medium (IGM) as the Universe became reion…
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 (…
CANUCS/Technicolor: JWST Medium Band Photometry Finds Half of the Star Formation at is Obscured
Nicholas Martis, Sunna Withers, Giordano Felicioni +19
We present a sample of 146 high-redshift () galaxies from the CANUCS/Technicolor surveys, showcasing photometry in every wide- and medium-band NIRCam filter in addition to a…
Detailed Study of Stars and Gas in a z = 8.3 Massive Merger with Extreme Dust Conditions
Anishya Harshan, Roberta Tripodi, Nicholas S. Martis +15
We present galaxy MACS0416-Y1 at z as observed by the CAnadian NIRISS Unbiased Cluster Survey (CANUCS). MACS0416-Y1 has been shown to have extreme dust proper…
Red, hot, and very metal poor: extreme properties of a massive accreting black hole in the first 500 Myr
Roberta Tripodi, Nicholas Martis, Vladan Markov +29
The James Webb Space Telescope (JWST) has recently discovered a new population of objects at high redshift referred to as `Little Red Dots' (LRDs). Their nature currently remains e…
