The broad-lined type Ic supernova 2020lao experienced an energetic explosion with no central-engine signatures

M. D. Stritzinger, T. J. Moriya, S. Bose +18

We present infant-phase observations of the SN Ic-BL 2020lao, including optical spectroscopy beginning 48 hrs after explosion. The explosion time was constrained by power-law fits…

JWST Observations of SN 2024ggi II: NIRSpec Spectroscopy and CO Modeling at 285 and 385 Days Past the Explosion

T. Mera, C. Ashall, P. Hoeflich +20

We present James Webb Space Telescope (JWST) NIRSpec observations of SN~2024ggi, spanning wavelengths of 1.7--5.5 micron at +285.51 and +385.27 days post-explosion. These nebular s…

Unraveling the Nature of the Nuclear Transient AT2020adpi

Paarmita Pandey, Jason Hinkle, Christopher Kochanek +13

Transient events associated with supermassive black holes provide rare opportunities to study accretion and the environments of supermassive black holes. We present a multiwaveleng…

Hot springs and dust reservoirs: JWST reveals the dusty, molecular aftermath of extragalactic stellar mergers

Viraj Karambelkar, Mansi Kasliwal, Ryan M. Lau +7

We present James Webb Space Telescope (JWST) observations of four Luminous Red Novae (LRNe): dusty, extragalactic transients from stellar mergers following common-envelope evolutio…

Near-Infrared Spectroscopy and Detection of Carbon Monoxide in the Type II Supernova SN 2023ixf

Seong Hyun Park, Jeonghee Rho, Sung-Chul Yoon +33

Core-collapse supernovae (CCSNe) may contribute a significant amount of dust in the early universe. Freshly formed coolant molecules (e.g., CO) and warm dust can be found in CCSNe…

JWST Observations of SN 2023ixf II: The Panchromatic Evolution Between 250 and 720 Days After the Explosion

K. Medler, C. Ashall, P. Hoeflich +60

We present the nebular phase spectroscopic and photometric observations of the nearby hydrogen-rich core-collapse supernova (CC-SN) 2023ixf, obtained through our JWST programs. The…
