Double Detonations on a Moving Mesh with : Characterizing Early Reddening in SNe Ia
Dillon Hasenour, Paul Duffell, Abigail Polin
Type Ia supernovae are useful as cosmological distance indicators and are significant sources of chemical enrichment in galaxies, but much about their origins remains uncertain. Th…
Tomography analysis of the intermediate-luminosity Type Iax SN 2024pxl
Barnabás Barna, Mridweeka Singh, Lindsey A. Kwok +90
We present an abundance tomography analysis of SN 2024pxl, an intermediate luminosity Type Iax supernova ( mag), with the most-detailed follow-up in the Type…
Exploring the effect of mixing in Low-Luminosity Type IIp Supernovae by modeling SN 2024abfl
Akshith Karri, Abigail Polin, Paul Duffell
Low-luminosity Type IIp supernovae (LLSNe) are SN IIps with peak magnitudes > -15.5 and plateau magnitudes between -13.5 and -15.5 in the V band. SN 2024abfl is an LLSN with a uniq…
JWST Nebular Spectroscopy of SN 2023qov: Circumstellar Dust Emission in a Normal Type Ia Supernova
Colin W. Macrie, Conor Larison, Huei Sears +43
We present panchromatic observations of the Type Ia supernova (SN Ia) 2023qov, ranging from 2 weeks before to 1 year after maximum light. JWST near- and mid-infrared sp…
A Novel Parameterization for Rapid Cooling in Supernova Remnants, with applications to the Pa 30 nebula
Miranda Pikus, Paul Duffell, Soham Mandal +1
We systematically study how cooling creates structural changes in supernova remnants as they evolve. Inspired by the peculiar morphology of the Pa 30 nebula, we adopt a framework i…
Measurement of anisotropies in Supernova Remnant observations and their interpretation using numerical models
Soham Mandal, Paul C. Duffell, Abigail Polin +1
Supernova remnants (SNRs) exhibit varying degrees of anisotropy, which have been extensively modeled using numerical methods. We implement a technique to measure anisotropies in SN…
Sculpting the Morphology of Supernova Remnant Pa 30 via Efficient Ejecta Cooling
Paul C. Duffell, Abigail Polin, Soham Mandal
We demonstrate in a proof-of-concept numerical hydrodynamics calculation that the narrow radial filamentary structures seen in Pa 30 could be generated through highly efficient coo…
