Connecting Lyman- and ionizing photon escape in the Sunburst Arc
M. Riley Owens, Keunho J. Kim, Matthew B. Bayliss +17
We investigate the Lyman- (Ly) and Lyman continuum (LyC) properties of the Sunburst Arc, a gravitationally lensed galaxy with a multiply-imaged, compact region leaki…
COOL-LAMPS VIII: Known wide-separation lensed quasars and their host galaxies reveal a lack of evolution in since
Aidan P. Cloonan, Gourav Khullar, Kate A. Napier +36
Wide-separation lensed quasars (WSLQs) are a rare class of strongly lensed quasars, magnified by foreground massive galaxy clusters, with typically large magnifications of the mult…
Deep rest-UV JWST/NIRSpec spectroscopy of early galaxies: the demographics of CIV and N-emitters in the reionization era
Michael W. Topping, Daniel P. Stark, Peter Senchyna +12
JWST has recently discovered a subset of reionization era galaxies with ionized gas that is metal poor in oxygen and carbon but heavily-enriched in nitrogen. This abundance pattern…
The First Billion Years, According to JWST
Angela Adamo, Hakim Atek, Micaela B. Bagley +46
With stunning clarity, JWST has revealed the Universe's first billion years. The scientific community is analyzing a wealth of JWST imaging and spectroscopic data from that era, an…
The Sunburst Arc with JWST: II. Observations of an Eta Carinae Analog at
S. Choe, T. Emil Rivera-Thorsen, H. Dahle +11
"Godzilla" is a peculiar object within the gravitationally lensed Sunburst Arc at . Despite being very bright, it appears in only one of the twelve lensed images of the sou…
The Sunburst Arc with JWST: III. An Abundance of Direct Chemical Abundances
Brian Welch, T. Emil Rivera-Thorsen, Jane Rigby +11
We measure the gas-phase abundances of the elements He, N, O, Ne, S, Ar, and Fe in an individual H\textsc{ii} region known to be leaking Lyman-continuum photons in the Sunburst Arc…
JWST NIRSpec High-resolution Spectroscopy of MACS0647-JD at z=10.167: Resolved [OII] Doublet and Electron Density in an Early Galaxy
Abdurro'uf, Rebecca L. Larson, Dan Coe +26
We present JWST/NIRSpec high-resolution spectroscopy G395H/F290LP of MACS0647-JD, a gravitationally lensed galaxy merger at . The new spectroscopy, which is acquired for…
JWST MIRI detections of H and [O III] and direct metallicity measurement of the lensed galaxy MACS0647JD
Tiger Yu-Yang Hsiao, Javier Álvarez-Márquez, Dan Coe +30
JWST spectroscopy has revolutionized our understanding of galaxies in the early universe. Covering wavelengths up to , NIRSpec can detect rest-frame optical emission…
The Sunburst Arc with JWST: I. Detection of Wolf-Rayet stars injecting nitrogen into a low-metallicity, proto-globular cluster leaking ionizing photons
T. Emil Rivera-Thorsen, J. Chisholm, B. Welch +13
We report the detection of a population of Wolf-Rayet (WR) stars in the Sunburst Arc, a strongly gravitationally lensed galaxy at redshift . As the brightest known lensed g…
Primordial Rotating Disk Composed of 15 Dense Star-Forming Clumps at Cosmic Dawn
S. Fujimoto, M. Ouchi, K. Kohno +43
Early galaxy formation, initiated by the dark matter and gas assembly, evolves through frequent mergers and feedback processes into dynamically hot, chaotic structures. In contrast…
TEMPLATES: Direct Abundance Constraints for Two Lensed Lyman-Break Galaxies
Brian Welch, Grace M. Olivier, Taylor A. Hutchison +19
Using integrated spectra for two gravitationally lensed galaxies from the JWST TEMPLATES Early Release Science program, we analyze faint auroral lines, which provide direct measure…
Metal-poor star formation at with JWST: new insight into hard radiation fields and nitrogen enrichment on 20 pc scales
Michael W. Topping, Daniel P. Stark, Peter Senchyna +11
Nearly a decade ago, we began to see indications that reionization-era galaxies power hard radiation fields rarely seen at lower redshift. Most striking were detections of nebular…
Bound star clusters observed in a lensed galaxy 460 Myr after the Big Bang
Angela Adamo, Larry D. Bradley, Eros Vanzella +25
The Cosmic Gems arc is among the brightest and highly magnified galaxies observed at redshift . However, it is an intrinsically UV faint galaxy, in the range of those no…
