A JWST/MIRI Study of Dust in a Sample of Normal Type IIP Core Collapse Supernovae
Bhagya M. Subrayan, David J. Sand, Olivia Culbert +24
Core collapse supernovae (CCSNe) are invoked as major dust producers in the early Universe, yet the amount of dust they form, the timescale over which it grows, and the physical co…
Entanglement Negativity in Noisy Quantum Volume Sampling
Elijah Pelofske, Stephan Eidenbenz
The Quantum Volume protocol uses scrambling random circuits to benchmark NISQ computers. Quantum Volume is generally well-regarded as a benchmark for small, noisy, quantum computer…
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…
Evidence for Asymmetric Ejecta and Circumstellar Material in SN 2023ixf Inferred from Extensive Nebular-phase Observations
Brian Hsu, Nathan Smith, K. Azalee Bostroem +34
We present extensive optical and near-infrared (NIR) observations of the nearby Type II supernova (SN II) 2023ixf in the nebular phase from +89 days to +749 days after explosion, s…
SN 2023rve: A Type II Supernova with No Nebular Oxygen
Melissa Rosowsky, Stefano Valenti, Aravind P. Ravi +21
We report on multiband photometric and spectroscopic observations of SN 2023rve, a nearby Type II supernova (SN II) discovered in galaxy NGC 1097 (D= Mpc). Nearby SNe…
JWST observations of SN 2024abup: First Detection of CO in a broad-lined Type Ic Supernova and Constraints on r-process Nucleosynthesis
Manisha Shrestha, Lindsey A. Kwok, David J. Sand +42
SN 2024abup is a nearby broad-lined Type Ic supernova (SN Ic-bl) in NGC 0681 at a distance of 23.3 \pm 1.6 Mpc. As energetic explosions of massive stars, SNe Ic-bl are considered a…
