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…
JWST Spectroscopy of Type Ia Supernova 2025rbs from Maximum Light to the Nebular Phase
Lindsey A. Kwok, Stéphane Blondin, Adam A. Miller +53
We present JWST observations of the Type Ia supernova (SN Ia) 2025rbs (14.5 Mpc) at +1, +23, and +84 days after B-band maximum, spanning peak light through a wavelength-depende…
Revealing the Structure and Magnetization of GRB Jets with ALMA Polarization Observations
Tanmoy Laskar, Collin T. Christy, Noah Franz +9
We present a systematic study of the currently available ALMA millimeter polarimetric sample of gamma-ray burst (GRB) afterglows. Our sample comprises 24 observations (20 new) of 1…
A Self-Consistent Framework for Synchrotron Equipartition Analysis
Coleman Rohde, Tanmoy Laskar, Noah Franz +3
Determining the energy, size, and velocity of synchrotron-emitting outflows is essential for testing models of their formation and evolution, but these quantities are often poorly…
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…
