Reaching for the stars -- JWST/NIRSpec spectroscopy of a lensed star candidate at
Lukas J. Furtak, Ashish K. Meena, Erik Zackrisson +31
We present JWST/NIRSpec observations of a highly magnified star candidate at a photometric redshift of , previously detected in JWST/NIRCam imaging of t…
Uncovering a Massive z~7.7 Galaxy Hosting a Heavily Obscured Radio-Loud QSO Candidate in COSMOS-Web
Erini Lambrides, Marco Chiaberge, Arianna Long +47
In this letter, we report the discovery of the highest redshift, heavily obscured, radio-loud AGN candidate selected using JWST NIRCam/MIRI, mid-IR, sub-mm, and radio imaging in th…
Powerful Radio-Loud Quasars are Triggered by Galaxy Mergers in the Cosmic Bright Ages
Peter Breiding, Marco Chiaberge, Erini Lambrides +14
While supermassive black holes are ubiquitous features of galactic nuclei, only a small minority are observed during episodes of luminous accretion. The physical mechanism(s) drivi…
JWST NIRSpec spectroscopy of the triply-lensed galaxy MACS0647JD
Tiger Yu-Yang Hsiao, Abdurro'uf, Dan Coe +38
We present JWST/NIRSpec prism spectroscopy of MACS0647-JD, the triply-lensed candidate discovered in HST imaging and spatially resolved by JWST imaging into two compone…
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…
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…
