Pulsational mass loss from supermassive stars creates the compact shells of Little Red Dots
Devesh Nandal, Igor Chilingarian, Chris Nagele +3
Little Red Dots (LRDs) have emerged as one of the central puzzles of the JWST era. Their spectra increasingly require dense gas close to the source, yet the physical origin of that…
Other red dots: A possible GLIMPSE of normal AGB stars at Cosmic Noon through extreme lensing
Lukas J. Furtak, Adi Zitrin, Erik Zackrisson +18
We report the discovery of four extremely faint () red point sources in recent ultra-deep JWST/NIRCam images of the strong lensing galaxy cluster Abell…
GLIMPSED: Direct evidence for a fast AGN-driven outflow from a z=6.64 Little Red Dot host galaxy
Damien Korber, Rui Marques-Chaves, Daniel Schaerer +15
We report the discovery of GLIMPSED-329380, a z=6.64 galaxy behind Abell S1063, which shows signs of an extreme ionised outflow driven by an active galactic nucleus (AGN). The deep…
The Engine and its Flows: Little Red Dot spectra are shaped by the column densities of their gas envelopes
Jorryt Matthee, Alberto Torralba, Gabriele Pezzulli +23
JWST data have enabled the abundant identification of compact broad Balmer line sources nicknamed the Little Red Dots. While they share broad lines with active galactic nuclei, the…
A Cosmic Miracle: A Remarkably Luminous Galaxy at Confirmed with JWST
Rohan P. Naidu, Pascal A. Oesch, Gabriel Brammer +43
JWST has revealed a stunning population of bright galaxies at surprisingly early epochs, , where few such sources were expected. Here we present the most distant example of t…
A spectroscopically confirmed, strongly lensed, metal-poor Type II supernova at z = 5.13
David A. Coulter, Conor Larison, Justin D. R. Pierel +88
Observing supernovae (SNe) in the early Universe (z > 3) provides a window into how both galaxies and individual stars have evolved over cosmic time, yet a detailed study of high-r…
