Sp1149 II: Spectroscopy of HII Regions Near the Critical Curve of MACS J1149 and Cluster Lens Models
Hayley Williams, Patrick Kelly, Wenlei Chen +3
Galaxy-cluster gravitational lenses enable the study of faint galaxies even at large lookback times, and, recently, time-delay constraints on the Hubble constant. There have been f…
Sp1149 I: Constraints on the Balmer L-sigma Relation for HII Regions in a Spiral Galaxy at Redshift z=1.49 Strongly Lensed by the MACS J1149 Cluster
Hayley Williams, Patrick Kelly, Wenlei Chen +3
The luminosities and velocity dispersions of the extinction-corrected Balmer emission lines of giant HII regions in nearby galaxies exhibit a tight correlation (~0.35 dex scatter).…
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…
The JWST Discovery of the Triply-imaged Type Ia "Supernova H0pe" and Observations of the Galaxy Cluster PLCK G165.7+67.0
Brenda L. Frye, Massimo Pascale, Justin Pierel +39
A Type Ia supernova (SN) at was discovered in James Webb Space Telescope Near Infrared Camera imaging of the galaxy cluster PLCK G165.7+67.0 (G165; ). The SN is…
Shock cooling of a red-supergiant supernova at redshift 3 in lensed images
Wenlei Chen, Patrick L. Kelly, Masamune Oguri +6
The core-collapse supernova of a massive star rapidly brightens when a shock, produced following the collapse of its core, reaches the stellar surface. As the shock-heated star sub…
The Magnificent Five Images of Supernova Refsdal: Time Delay and Magnification Measurements
Patrick L. Kelly, Steven Rodney, Tommaso Treu +28
In late 2014, four images of Supernova (SN) "Refsdal," the first known example of a strongly lensed SN with multiple resolved images, were detected in the MACS J1149 galaxy-cluster…
Constraints on the Hubble constant from Supernova Refsdal's reappearance
Patrick L. Kelly, Steven Rodney, Tommaso Treu +27
The gravitationally lensed Supernova Refsdal appeared in multiple images, produced through gravitational lensing by a massive foreground galaxy cluster. After the supernova appeare…
An Empirical reionization history model inferred from the low-redshift Lyman continuum survey and the star-forming galaxies at
Yu-Heng Lin, Claudia Scarlata, Hayley Williams +8
We present a new analysis of the rest-frame UV and optical spectra of a sample of three galaxies discovered behind the gravitational lensing cluster RX\,J2129.4+0009. We comb…
A search for transients in the Reionization Lensing Cluster Survey (RELICS): Three new supernovae
Miriam Golubchik, Adi Zitrin, Justin Pierel +16
The Reionization Cluster Survey (RELICS) imaged 41 galaxy clusters with the Hubble Space Telescope (HST), in order to detect lensed and high-redshift galaxies. Each cluster was ima…
The GLASS-JWST Early Release Science Program. II. Stage I release of NIRCam imaging and catalogs in the Abell 2744 region
Diego Paris, Emiliano Merlin, Adriano Fontana +27
We present images and a multi-wavelength photometric catalog based on all of the JWST NIRCam observations obtained to date in the region of the Abell 2744 galaxy cluster. These dat…
