GLIMPSE-D: An Exotic Balmer-Jump Object at z=6.20? Revisiting Photometric Selection and the Cosmic Abundance of Pop III Galaxies
Seiji Fujimoto, Yoshihisa Asada, Rohan P. Naidu +19
We present deep JWST/NIRSpec G395M spectroscopy of GLIMPSE-16043, a promising Pop III candidate originally identified through NIRCam photometry as having weak [OIII]$λ\lam…
THRILS -- The High-(Redshift+Ionization) Line Search: Program Description & Redshift Catalog
Taylor A. Hutchison, Rebecca L. Larson, Pablo Arrabal Haro +46
To date, many spectroscopic confirmations of z>7 galaxies have been obtained using JWST/NIRSpec prism observations, with most of their physical properties inferred from these obser…
VENUS: A Strongly Lensed Clumpy Galaxy at behind the Galaxy Cluster MACS J0257.1-2325
Minami Nakane, Vasily Kokorev, Seiji Fujimoto +75
We present the discovery of a strongly lensed galaxy at , dubbed the ``Misty Moons'', identified in the JWST Treasury Survey, Vast Exploration for Nascent, Unexplored S…
Significant Evidence of an AGN Contribution in GHZ2 at z = 12.34
Oscar A. Chavez Ortiz, Steven L. Finkelstein, Adele Plat +18
GHZ2 is among the highest-redshift galaxies discovered to date, exhibiting a spectrum rich with prominent emission lines in the rest-frame ultraviolet (UV) and optical. These featu…
A GLIMPSE of Intermediate Mass Black holes in the epoch of reionization: Witnessing the Descendants of Direct Collapse?
Qinyue Fei, Seiji Fujimoto, Rohan P. Naidu +17
JWST has revealed an abundance of supermassive black holes (BHs) in the early Universe, and yet the lowest mass seed black holes that gave rise to these populations remain elusive.…
Discovery of Multiply Ionized Iron Emission Powered by an Active Galactic Nucleus in a z~7 Little Red Dot
Erini Lambrides, Rebecca Larson, Taylor Hutchison +50
Some of the most puzzling discoveries of NASA's JWST in the early Universe surround the surprising abundance of compact red sources, which show peculiar continuum shapes and broad…
BlackTHUNDER: Evidence of three massive black holes in a z~5 galaxy
Hannah Übler, Giovanni Mazzolari, Roberto Maiolino +41
We present observational evidence of three massive, accreting black holes (BHs) in the z=5.0167 galaxy J0148-4214 from JWST/NIRSpec-IFU spectroscopy. The BHs are revealed through b…
A direct black hole mass measurement in a Little Red Dot at the Epoch of Reionization
Ignas Juodžbalis, Cosimo Marconcini, Francesco D'Eugenio +37
Recent discoveries of faint active galactic nuclei (AGN) at the redshift frontier have revealed a plethora of broad \Halpha emitters with optically red continua, named Little Red D…
Little Red Dots and their Progenitors from Direct Collapse Black Holes
Junehyoung Jeon, Boyuan Liu, Volker Bromm +7
The James Webb Space Telescope (JWST) has discovered a new population of objects, the Little Red Dots (LRDs), characterized by V-shaped spectra indicative of strong breaks around t…
CAPERS-LRD-z9: A Gas Enshrouded Little Red Dot Hosting a Broad-line AGN at z=9.288
Anthony J. Taylor, Vasily Kokorev, Dale D. Kocevski +49
We present CAPERS-LRD-z9, a little red dot (LRD) which we confirm to be a broad-line AGN (BLAGN). First identified as a high-redshift LRD candidate from PRIMER NIRCam pho…
Bursty or heavy? The surprise of bright Population III systems in the Reionization era
Alessandra Venditti, Julian B. Munoz, Volker Bromm +3
The nature of the first, so-called Population III (Pop III) stars has for long remained largely unconstrained. However, the James Webb Space Telescope (JWST) finally opened new con…
GLIMPSE: An ultra-faint 10 Pop III Galaxy Candidate and First Constraints on the Pop III UV Luminosity Function at
Seiji Fujimoto, Rohan P. Naidu, John Chisholm +32
Detecting the first generation of stars, Population III (PopIII), has been a long-standing goal in astrophysics, yet they remain elusive even in the JWST era. Here we present a nov…
