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…
RUBIES: JWST/NIRSpec resolves evolutionary phases of dusty star-forming galaxies at
Olivia R. Cooper, Gabriel Brammer, Kasper E. Heintz +24
The dearth of high quality spectroscopy of dusty star-forming galaxies (DSFGs) -- the main drivers of the assembly of dust and stellar mass at the peak of activity in the Universe…
Extreme Ionizing Properties of Metal-Poor, Muv ~ -12 Star Complex in the first Gyr
E. Vanzella, F. Loiacono, M. Messa +38
We report the serendipitous discovery of a faint (M_UV > -12.2), low-metallicity (Z ~ 0.02 Zsun), ionizing source (dubbed T2c) with a spectroscopic redshift of z=6.146. T2c is part…
CANUCS: UV and Ionising Properties of Dwarf Star Forming Galaxies at z = 5 to 7
Anishya Harshan, MaruÅ¡a BradaÄ, Roberto Abraham +14
The epoch of reionisation progressed through the emission of ionising photons from galaxies to their local intergalactic medium. In this work, we characterise the dwarf star-formin…
When, Where, and How Star Formation Happens in a Galaxy Pair at Cosmic Noon Using CANUCS JWST/NIRISS Grism Spectroscopy
Vicente Estrada-Carpenter, Marcin Sawicki, Gabe Brammer +13
Spatially resolved studies are key to understanding when, where, and how stars form within galaxies. Using slitless grism spectra and broadband imaging from the CAnadian NIRISS Unb…
