An unambiguous AGN and a Balmer break in an Ultraluminous Little Red Dot at z=4.47 from Ultradeep UNCOVER and All the Little Things Spectroscopy
Ivo Labbe, Jenny E. Greene, Jorryt Matthee +37
We present a detailed exploration of the most optically-luminous Little Red Dot (erg/s, erg/s, F444W=22AB) found to date. Located in the Abell 2744 fie…
Environmental Evidence for Overly Massive Black Holes in Low Mass Galaxies and a Black Hole - Halo Mass Relation at
Jorryt Matthee, Rohan P. Naidu, Gauri Kotiwale +14
JWST observations have unveiled faint active galactic nuclei (AGN) at high-redshift that provide insights on the formation of supermassive black holes (SMBHs) and their coevolution…
The MUSE Extremely Deep Field: Classifying the Spectral Shapes of Lya Emitting Galaxies
E. Vitte, A. Verhamme, P. Hibon +14
The Hydrogen Lyman-alpha (Lya) line shows a large variety of shapes which is caused by factors at different scales, from the interstellar medium to the intergalactic medium. This w…
Little Red Dots at an Inflection Point: Ubiquitous "V-Shaped" Turnover Consistently Occurs at the Balmer Limit
David J. Setton, Jenny E. Greene, Anna de Graaff +18
Among the most puzzling early discoveries of JWST are "Little Red Dots" -- compact red sources that host broad Balmer emission lines and, in many cases, exhibit a "V shaped" change…
MUSEQuBES: Connecting HI absorption with Ly emitters at
Eshita Banerjee, Sowgat Muzahid, Joop Schaye +6
We present a comprehensive analysis of HI absorption around 96 lya emitters (LAEs) at (median lya luminosity erg.s). These LAEs were identifie…
Tracing star formation across cosmic time at tens of parsec-scales in the lensing cluster field Abell 2744
Adélaïde Claeyssens, Angela Adamo, Matteo Messa +5
We present a sample of 1956 individual stellar clumps at redshift 0.7<z<10, detected with JWST/NIRCam in 476 galaxies lensed by the galaxy cluster Abell2744. The lensed clumps pres…
