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…

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…

SN 2022erq: A Superluminous Thermonuclear Supernova with Escalating Preexplosion Mass Loss

Qian Zhai, Jujia Zhang, Xiaofeng Wang +51

We present a photometric and spectroscopic study of the superluminous Type Ia supernova SN 2022erq. Its early spectra, dominated by iron-group elements with weak intermediate-mass…

Line Polarization of Si II 6355 Å in Type Ia Supernovae: A New Statistical Approach to Probe the Explosion Physics and Diversity

Aleksandar Cikota, Peter Hoeflich, Dietrich Baade +6

Spectropolarimetry provides a unique probe of ejecta asphericities, offering direct insights into the underlying explosion physics of Type Ia supernovae (SNe Ia). We analyze the st…

Ejecta masses in Type Ia Supernovae -- Implications for the Progenitor and the Explosion Scenario

Zsófia Bora, Réka Könyves-Tóth, József Vinkó +35

The progenitor system(s) as well as the explosion mechanism(s) of thermonuclear (Type Ia) supernovae are long-standing issues in astrophysics. Here we present ejecta masses and oth…
