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…
Little red dot variability over a century reveals black hole envelope via a giant Einstein cross
Zijian Zhang, Mingyu Li, Masamune Oguri +79
"Little red dots" (LRDs) represent a new population of astronomical objects uncovered by JWST whose nature remains debated. Although many LRDs are suspected as active galactic nucl…
An Ancient Descendant of the First Galaxies
Jacqueline Antwi-Danso, Adam Muzzin, Luke Robbins +18
JWST has revealed unexpectedly bright galaxies in the first 500 Myr after the Big Bang. Their overabundance suggests that they are preferentially observed during burst phases, wher…
Resolving dust and Lyα emission in a lensed galaxy at the epoch of reionization with JWST/CANUCS
V. Markov, M. Bradač, V. Estrada-Carpenter +20
Lyman emission is highly sensitive to dust and neutral hydrogen and is therefore expected to be strongly suppressed in dusty or gas-rich galaxies during the epoch of reionizati…
JWST's GLIMPSE: an overview of the deepest probe of early galaxy formation and cosmic reionization
Hakim Atek, John Chisholm, Vasily Kokorev +44
We present an overview of the JWST GLIMPSE program, highlighting its survey design, primary science goals, gravitational lensing models, and first results. GLIMPSE provides ultra-d…
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…
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.…
The rise and fall of Little Red Dots could be driven by the environment
Rosa M. Mérida, Gaia Gaspar, Yoshihisa Asada +9
The Little Red Dot (LRD) paradigm comprises three main unknowns that are intrinsically connected: (1) What is the nature of these sources? (2) How do they form? (3) How do they evo…
The Stellar Mass and Age Distributions of Star-Forming Clumps at in JWST CANUCS: Implications for Clump Formation and Destruction
Visal Sok, Adam Muzzin, Vivian Yun Yan Tan +12
We investigate the resolved properties of star-forming clumps and their host galaxies at in the JWST CANUCS fields. We find that the fraction of clumpy galaxies peaks nea…
Star Formation under a Cosmic Microscope: Highly magnified z = 11 galaxy behind the Bullet Cluster
Maruša Bradač, Jon Judež, Chris Willott +20
We present measurements of stellar population properties of a newly discovered spectroscopically confirmed , gravitationally lensed galaxy, using JWST NIRS…
Spatially and Dynamically Extended Molecular Gas in Stephan's Quintet Revealed by ALMA CO(1-0) Total Power Mapping
Fumiya Maeda, Shinya Komugi, Kazuyuki Muraoka +15
We present ALMA Total Power CO(1-0) mapping of Stephan's Quintet (SQ), a prototypical compact galaxy group, with a uniform noise level at a spatial scale of ~25 kpc. These observat…
Metal-Poor Star-Forming Clumps in Cosmic Noon Galaxies: Evidence for Gas Inflow and Chemical Dilution Using JWST NIRISS
Vicente Estrada-Carpenter, Marcin Sawicki, Roberto Abraham +16
The formation and evolution of galaxies are intricately linked to the baryon cycle, which fuels star formation while shaping chemical abundances within galaxies. Investigating the…
