Ultraviolet to Infrared Spectroscopy of the Type Ibn SN 2023tsz Suggests a Lower-mass Progenitor

Sergiy S. Vasylyev, Griffin Hosseinzadeh, Luc Dessart +42

Type Ibn supernovae are stripped-envelope explosions whose spectra indicate interaction with dense, helium-rich and hydrogen-poor circumstellar material (CSM), making them importan…

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…

JWST's PEARLS: Mothra, a new kaiju star at z=2.091 extremely magnified by MACS0416, and implications for dark matter models

J. M. Diego, Bangzheng Sun, Haojing Yan +28

We report the discovery of Mothra, an extremely magnified monster star, likely a binary system of two supergiant stars, in one of the strongly lensed galaxies behind the galaxy clu…

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…

Spectroscopy of the Supernova H0pe Host Galaxy at Redshift 1.78

M. Polletta, M. Nonino, B. Frye +42

Supernova (SN) H0pe was discovered as a new transient in James Webb Space Telescope (JWST) NIRCam images of the galaxy cluster PLCK G165.7+67.0 taken as part of the "Prime Extragal…

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…
