JWST Nebular Spectroscopy of SN 2023qov: Circumstellar Dust Emission in a Normal Type Ia Supernova
Colin W. Macrie, Conor Larison, Huei Sears +42
We present panchromatic observations of the Type Ia supernova (SN Ia) 2023qov, ranging from 2 weeks before to 1 year after maximum light. \textit{JWST} near- and mid-in…
SN 2024iss: A Multi-Wavelength Exposé of a Type IIb Supernova with an Early-Time Ultraviolet Spectrum and Shock Breakout Constraints
Rujula Yete, Wynn Jacobson-Galan, Ferdinand Ferdinand +49
We present multi-wavelength observations and a comprehensive analysis of the nearby (D14 Mpc) Type IIb supernova (SN IIb) 2024iss. Observations of SN2024iss include an early…
AT 2024ahzi: A Type IIP Supernova Discovered by the LSST Commissioning Camera
Kaylee de Soto, V. Ashley Villar, Jared A. Goldberg +25
As part of its commissioning, the Vera C. Rubin Observatory observed several fields repeatedly for a month with ComCam, an instrument that uses the same hardware as the LSST camera…
An Archival Optical Counterpart Search for Extragalactic Fast X-Ray Transients Discovered by Einstein Probe
Run-Duo Liang, Wen-Xiong Li, Liang-Duan Liu +50
Extragalactic fast X-ray transients (eFXTs) represent a rapidly growing class of high-energy phenomena, whose physical origins remain poorly understood. With its wide-field, sensit…
A Panchromatic View of Late-time Shock Power in the Type II Supernova 2023ixf
W. V. Jacobson-Galán, L. Dessart, C. D. Kilpatrick +39
We present multi-wavelength observations of the type II supernova (SN II) 2023ixf during its first two years of evolution. We combine ground-based optical/NIR spectroscopy with Hub…
JWST Observations of SN 2023ixf I: Completing the Early Multi-Wavelength Picture with Plateau-phase Spectroscopy
J. M. DerKacy, C. Ashall, E. Baron +46
We present and analyze panchromatic (0.35--14 m) spectroscopy of the Type II supernova 2023ixf, including near- and mid-infrared spectra obtained 33.6 days after explosion durin…
