Peak 'Nebular' Emission and Early Flux Excesses in Ca-strong Supernovae
C. -G. Touchard-Paxton, K. Maguire, C. Frohmaier +27
Calcium-strong supernovae (Ca-strong SNe) are a class of thermonuclear transient characterised by rapid photometric evolution (rise times of <= 16 d) and nebular-phase spectra domi…

An analysis of the Type Ia SN 2024gy and a comparison of different host extinction estimation techniques
Jacco H. Terwel, Kate Maguire, Cillian O'Donnell +38
Type Ia supernovae (SNe Ia) are well-known standardisable candles, and are one of the main ways to measure the distance to their host galaxies. However, extinction due to interstel…

Violent mergers revisited: The origin of the fastest stars in the Galaxy
Rüdiger Pakmor, Ken J. Shen, Aakash Bhat +12
Binary systems of two carbon-oxygen white dwarfs are one of the most promising candidates for the progenitor systems of Type Ia supernovae. Violent mergers, where the primary white…
