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…
Superlinear Type II Superluminous Supernovae 2017fck and 2019cmv: A Possible Origin from Interacting Thermonuclear Supernovae
Daichi Hiramatsu, Takashi J. Moriya, D. Andrew Howell +9
Additional power sources to traditional supernovae (SNe) are necessary to account for the extreme luminosities of superluminous SNe (SLSNe). A main power source for hydrogen-rich S…
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 2020bij and a Possible Slow-Rise High-Velocity Subclass of Type IIP Supernovae
Sondos Mohsen-Tanev, Iair Arcavi, Shahar Bracha +17
Mapping how the explosion properties of Type II supernovae (SNe II) relate to the properties of their progenitors can provide strong constraints for understanding the final evoluti…
