Spectroscopic confirmation of four metal-poor galaxies at z=10.3-13.2
Emma Curtis-Lake, Stefano Carniani, Alex Cameron +56
Finding and characterising the first galaxies that illuminated the early Universe at cosmic dawn is pivotal to understand the physical conditions and the processes that led to the…
Identification and properties of intense star-forming galaxies at redshifts z>10
B. E. Robertson, S. Tacchella, B. D. Johnson +53
Surveys with James Webb Space Telescope (JWST) have discovered candidate galaxies in the first 400 Myr of cosmic time. Preliminary indications have suggested these candidate galaxi…

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…
CEERS Key Paper I: An Early Look into the First 500 Myr of Galaxy Formation with JWST
Steven L. Finkelstein, Micaela B. Bagley, Henry C. Ferguson +64
We present an investigation into the first 500 Myr of galaxy evolution from the Cosmic Evolution Early Release Science (CEERS) survey. CEERS, one of 13 JWST ERS programs, targets g…
JWST reveals a possible galaxy merger in triply-lensed MACS0647JD
Tiger Yu-Yang Hsiao, Dan Coe, Abdurro'uf +63
MACS0647JD is a triply-lensed galaxy originally discovered with the Hubble Space Telescope. Here we report new JWST imaging, which clearly resolves MACS0647JD as ha…
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…
JWST's PEARLS: Prime Extragalactic Areas for Reionization and Lensing Science: Project Overview and First Results
Rogier A. Windhorst, Seth H. Cohen, Rolf A. Jansen +82
We give an overview and describe the rationale, methods, and first results from NIRCam images of the JWST "Prime Extragalactic Areas for Reionization and Lensing Science" ("PEARLS"…
Webb's PEARLS: Bright 1.5--2.0 micron Dropouts in the Spitzer/IRAC Dark Field
Haojing Yan, Seth H. Cohen, Rogier A. Windhorst +35
Using the first epoch of four-band NIRCam observations obtained by the James Webb Space Telescope (JWST) Prime Extragalactic Areas for Reionization and Lensing Science Program in t…
Optical throughput and sensitivity of JWST NIRSpec
G. Giardino, R. Bhatawdekar, S. M. Birkmann +13
To achieve its ambitious scientific goals, the Near-Infrared Spectrograph, NIRSpec, on board the Webb Space Telescope, needs to meet very demanding throughput requirements, here qu…
JWST Imaging of Earendel, the Extremely Magnified Star at Redshift
Brian Welch, Dan Coe, Erik Zackrisson +60
The gravitationally lensed star WHL0137-LS, nicknamed Earendel, was identified with a photometric redshift based on images taken with the Hubble Space Tele…
JWST NIRCam+NIRSpec: Interstellar medium and stellar populations of young galaxies with rising star formation and evolving gas reservoirs
Sandro Tacchella, Benjamin D. Johnson, Brant E. Robertson +37
We present an interstellar medium and stellar population analysis of three spectroscopically confirmed galaxies in the ERO JWST NIRCam and JWST NIRSpec data of the SMACS J072…
Dusty Starbursts Masquerading as Ultra-high Redshift Galaxies in JWST CEERS Observations
Jorge A. Zavala, Veronique Buat, Caitlin M. Casey +121
Lyman Break Galaxy (LBG) candidates at z>10 are rapidly being identified in JWST/NIRCam observations. Due to the (redshifted) break produced by neutral hydrogen absorption of rest-…
Hubble Asteroid Hunter: II. Identifying strong gravitational lenses in HST images with crowdsourcing
Emily O. Garvin, Sandor Kruk, Claude Cornen +3
The Hubble Space Telescope (HST) archives constitute a rich dataset of high resolution images to mine for strong gravitational lenses. While many HST programs specifically target s…
