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…

Improving photometric redshifts of Epoch of Reionization galaxies: a new empirical transmission curve with neutral hydrogen damping wing Ly absorption

Yoshihisa Asada, Guillaume Desprez, Chris J. Willott +12

We present a new analytical model for the attenuation to Epoch of Reionization (EoR) galaxies by proximate neutral hydrogen gas. Many galaxy spectra in the EoR taken by JWST have s…

CANUCS: Constraining the MACS J0416.1-2403 Strong Lensing Model with JWST NIRISS, NIRSpec and NIRCam

Gregor Rihtaršič, Maruša Bradač, Guillaume Desprez +18

(Abridged) The strong lensing models of galaxy clusters rely on the number and quality of multiple images with spectroscopic redshifts. We present an updated strong lensing model o…

Spatially resolved emission lines in galaxies at from the JADES survey: evidence for enhanced central star formation

Roberta Tripodi, Francesco D'Eugenio, Roberto Maiolino +18

We present the first statistical investigation of spatially resolved emission-line properties in a sample of 63 low-mass galaxies at , using JWST/NIRSpec MSA data from…

CANUCS: An Updated Mass and Magnification Model of Abell 370 with JWST

Rachel Gledhill, Victoria Strait, Guillaume Desprez +9

We report an updated mass and magnification model of galaxy cluster Abell 370 using new NIRCam and NIRISS data from the CAnadian NIRISS Unbiased Cluster Survey (CANUCS). Using Lens…

The Firefly Sparkle: The Earliest Stages of the Assembly of A Milky Way-type Galaxy in a 600 Myr Old Universe

Lamiya Mowla, Kartheik Iyer, Yoshihisa Asada +19

The most distant galaxies detected by JWST are assembling in a Universe that is less than 5\% of its present age. At these times, the progenitors of galaxies like the Milky Way are…
