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…
The AURORA Survey: The Mass -- Metallicity and Fundamental Metallicity Relations at Based Purely on Direct Metallicities
Ali Ahmad Khostovan, Ryan L. Sanders, Alice E. Shapley +14
We present new constraints on the Mass -- Metallicity (MZR) and Fundamental Metallicity Relations (FMR) using a sample of 34 galaxies at (median ). The…
Spatially Resolved Physical Properties of Young Star Clusters and Star-forming Clumps in the Brightest z>6 Galaxy, the Strongly Lensed Cosmic Spear at z=6.2
Abdurro'uf, Dan Coe, Tom Resseguier +49
We present spatially resolved analysis of stellar populations in the brightest galaxy known to date (AB mag 23), the strongly lensed MACS0308zD1 (dubbed the ``Cosmic Spear…
A Fleeting GLIMPSE of N/O Enrichment at Cosmic Dawn: Evidence for Wolf Rayet N Stars in a z = 6.1 Galaxy
Danielle A. Berg, Rohan P. Naidu, John Chisholm +18
We present the discovery of extreme nitrogen enrichment by Wolf Rayet nitrogen stars (WN) in the metal-poor (~10% Z_odot), lensed, compact (R_eff ~ 20 pc) galaxy RXCJ2248 at z=6.1,…
The AURORA Survey: Ionizing Photon Production Efficiency with Minimal Nebular Dust Attenuation Systematics
Anthony J. Pahl, Alice Shapley, Naveen A. Reddy +11
We present ionizing photon production efficiencies () for 63 z=1.5-6.9 star-forming galaxies using precise nebular dust attenuation corrections from the JWST/AURORA su…
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.…
