Outflows in the Early Universe: Neutral gas Absorption in Galaxies at z > 3 from low-resolution JWST Spectroscopy
Matteo Sapori, Sirio Belli, Letizia Bugiani +14
Recent JWST/NIRSpec observations have shown that Na I D absorption tracing neutral gas outflows is widespread in massive galaxies at Cosmic Noon (-), but their prevalenc…
(Re)solving the Complex Multiscale Morphology and V-shaped Spectral Energy Distribution of a Newly Discovered Strongly Lensed Little Red Dot in A383
Josephine F. W. Baggen, Pieter van Dokkum, Ivo Labbé +1
The paper reports JWST NIRCam observations of a strongly lensed, luminous "little red dot" galaxy at redshift 6.0 behind the cluster A383, revealing a complex morphology with disti…
The metallicities of little red dot host galaxies: LRDs are metal poor, but not pristine
G. P. Nikopoulos, D. Watson, C. L. Pollock +4
Little Red Dots (LRDs) are a population of high-z sources discovered by JWST whose compactness, broad permitted lines, strong absorption features, continuum shapes and luminosities…
A Census of the 200 Most Massive Galaxies Spectroscopically Observed with JWST at zspec 3-15
Mengyuan Xiao, Pascal A. Oesch, Longji Bing +26
Massive galaxies provide strong tests of galaxy formation models, yet a comprehensive spectroscopic view of their properties and demographics in the early Universe has remained elu…
JWST spectroscopy of galaxies at : Damped Ly absorbers reveal efficient star formation and hidden redshift biases
Kasper E. Heintz, Clara L. Pollock, Joris Witstok +23
Recent observations with JWST have revealed a remarkable population of surprisingly luminous galaxies at redshifts . Their abundance exceed predictions from simulations and e…
Little Red Dots as Intermediate Mass, Super-Eddington Engines: Insights from Type IIn Supernovae and The 1837-1856 Great Eruption of Carinae
Rohan P. Naidu, Jorryt Matthee, Anna de Graaff +20
JWST's Little Red Dots (LRDs) display a unique constellation of features that do not occur simultaneously in any other class of galaxies or AGN. Here we observe that many of these…
