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…
Examining extinction distributions for type Ia supernovae in simulated 3D galaxies
João Duarte, Santiago González-Gaitán, Ana M. Mourão +2
Dust extinction and reddening greatly contribute to type Ia supernovae (SNe Ia) observed color and magnitude variations. The models used to describe the extinction probability dens…
A Faint Progenitor System for the Faint Supernova 2024vjm
Erez A. Zimmerman, Avishay Gal-Yam, Paul J. Groot +68
Type Ia Supernovae (SNe Ia) are well known for their role as standardizable cosmological candles. Their uniformity is credited to their single origin as thermonuclear explosions of…
Narrow absorption lines from intervening material in supernovae. IV. Type Ia supernovae: Na I D line strength relating to external material and intrinsic properties
Santiago González-Gaitán, Claudia P. Gutiérrez, João Duarte +4
Type Ia supernovae (SNe Ia) are thermonuclear runaways of some white dwarfs in binary systems. They have been extensively studied, yet their progenitor and explosion mechanisms rem…
Characteristic Critical Collapse of a Yang-Mills Field With Null Infinity
Rita P. Santos, Krinio Marouda, David Hilditch
Solutions to the Einstein equations near the threshold of black hole formation exhibit remarkable behavior known as critical phenomena gravitational collapse. In this work we perfo…
