Two Decades of Dust Evolution in SN 2005af through JWST, Spitzer, and Chemical Modeling
Arkaprabha Sarangi, Szanna Zsiros, Tamas Szalai +20
The evolution of dust in core-collapse supernovae (SNe), in general, is poorly constrained owing to a lack of infrared observations after a few years from explosion. Most theories…
Hydrodynamical modeling of SN 2025kg associated with the Fast X-ray Transient EP250108a
L. M. Roman Aguilar, M. C. Bersten
Supernovae (SNe) associated with X-Ray Flashes (XRFs) are extremely rare. Therefore, the discovery of each new object in this class offers a unique opportunity to improve our under…
The nebular phase of SN 2024ggi: a low-mass progenitor with no signs of interaction
L. Ferrari, G. Folatelli, K. Ertini +14
Context: SN 2024ggi is a Type II supernova (SN) discovered in the nearby galaxy NGC 3621 (D Mpc) on 2024 April 03.21 UT. Its proximity enabled a detailed investi…
SN2022jli modeled with a Ni double-layer and a magnetar
Mariana Orellana, Melina C. Bersten, Claudia P. Gutiérrez
We study the bolometric evolution of the exceptional Type Ic Supernova (SN) 2022jli, aiming to understand the underlying mechanisms responsible for its distinctive double-peaked li…
Rapid follow-up observations of infant supernovae with the Gran Telescopio Canarias
LluÃs Galbany, Claudia P. Gutiérrez, Lara Piscarreta +21
The first few hours of a supernova (SN) contain significant information about the progenitor system. The most modern wide-field surveys that scan the sky repeatedly every few days…
A magnetar powers the luminous supernova 2023pel, associated with a long gamma-ray burst
L. M. Roman Aguilar, M. M. Saez, K. Ertini +1
We explore SN 2023pel, the most recent event associated with gamma-ray bursts (GRBs), specifically GRB 230812B. SN 2023pel has a high luminosity and low expansion velocities compar…
