Massive galaxy formation caught in action at z~5 with JWST
Shuowen Jin, Nikolaj B. Sillassen, Georgios E. Magdis +13
We report the discovery of a compact group of galaxies, CGG-z5, at z~5.2 in the EGS field covered by the JWST/CEERS survey. CGG-z5 was selected as the highest overdensity of galaxi…
The gas and stellar content of a metal-poor galaxy at as revealed by JWST and ALMA
K. E. Heintz, C. Giménez-Arteaga, S. Fujimoto +27
We present a joint analysis of the galaxy S04590 at based on NIRSpec, NIRCam, and NIRISS observations obtained through as part of Early Release Observations programme of…
JWST and ALMA Multiple-Line Study in and around a Galaxy at : Optical to FIR Line Ratios and the Onset of an Outflow Promoting Ionizing Photon Escape
Seiji Fujimoto, Masami Ouchi, Kimihiko Nakajima +33
We present ALMA deep spectroscopy for a lensed galaxy at with whose optical nebular lines and stellar continuum are detec…
No Need for Extreme Stellar Masses at z~7: A Test-case Study of COS-87259
Sophie E. van Mierlo, Karina I. Caputi, Vasily Kokorev
Recent controversy regarding the existence of massive (log(M/Msun)>11) galaxies at z>6 poses a challenge for galaxy formation theories. Hence, it is of critical importance to under…
Two lensed star candidates at behind the galaxy cluster MACS J0647.7+7015
Ashish Kumar Meena, Adi Zitrin, Yolanda Jiménez-Teja +24
We report the discovery of two extremely magnified lensed star candidates behind the galaxy cluster MACS J0647.7+7015, in recent multi-band James Webb Space Telescope (JWST) NIRCam…
JWST/NIRCam Probes Young Star Clusters in the Reionization Era Sunrise Arc
E. Vanzella, A. Claeyssens, B. Welch +27
Star cluster formation in the early universe and their contribution to reionization remains to date largely unconstrained. Here we present JWST/NIRCam imaging of the most highly ma…
COSMOS-Web: An Overview of the JWST Cosmic Origins Survey
Caitlin M. Casey, Jeyhan S. Kartaltepe, Nicole E. Drakos +82
We present the survey design, implementation, and outlook for COSMOS-Web, a 255 hour treasury program conducted by the James Webb Space Telescope in its first cycle of observations…
A solar metallicity galaxy at 7? Possible detection of the [N II] 122 m and [O III] 52 m lines
Meghana Killi, Darach Watson, Seiji Fujimoto +9
We present the first detection of the [N II] 122 m and [O III] 52 m lines for a reionisation-epoch galaxy. Based on these lines and previous [C II] 158 m and [O III] 88 $μ…
COSMOS2020: Identification of High-z Protocluster Candidates in COSMOS
Malte Brinch, Thomas R. Greve, John R. Weaver +20
We conduct a systematic search for protocluster candidates at in the COSMOS field using the recently released COSMOS2020 source catalog. We select galaxies using a numbe…
High-Redshift Galaxy Candidates at as Revealed by JWST Observations of WHL0137-08
Larry D. Bradley, Dan Coe, Gabriel Brammer +25
We report the discovery of four galaxy candidates observed 450 - 600 Myr after the Big Bang with photometric redshifts between z ~ 8.3 - 10.2 measured using the JWST NIRCam imaging…
Templates for Fitting Photometry of Ultra-High-Redshift Galaxies
Charles L. Steinhardt, Vasily Kokorev, Vadim Rusakov +2
Recent data from the James Webb Space Telescope allow a first glimpse of galaxies at . The most successful tool for identifying ultra-high-redshift candidates and inf…
A First Look into the Nature of JWST/MIRI 7.7 micron Sources from SMACS 0723
Edoardo Iani, Karina I. Caputi, Pierluigi Rinaldi +1
Until now, our knowledge of the extragalactic Universe at mid-IR wavelengths (> 5 microns) was limited to rare active galactic nuclei (AGN) and the brightest normal galaxies up to…
The MOSDEF Survey: A New View of a Remarkable z=1.89 Merger
Jordan N. Runco, Alice E. Shapley, Mariska Kriek +13
We present a detailed study of a galaxy merger taking place at in the GOODS-S field. Here we analyze Keck/MOSFIRE spectroscopic observations from the MOSFIRE Deep Evolutio…
