SN 2024abvb: a Type Ibn/Icn supernova with evidence of helium and an extreme offset from its host galaxy
Callum Aster, Cosimo Inserra, Andrea Pastorello +27
We present spectroscopic and photometric observations and analysis of SN 2024abvb, a peculiar transitional Type Ibn/Icn supernova located at an unusually large projected distance f…
Between Plateaus and Slopes: A Data-Driven Exploration of Spectral Diversity Across Type IIP/L Supernovae
Géza Csörnyei, Claudia P. Gutiérrez
Type II supernovae (SNe II) have been traditionally separated into several subgroups based on their photometric and spectroscopic properties, but whether these represent distinct p…
Photometric classification of supernovae detected by the Zwicky Transient Facility using noise augmentation
A. Townsend, J. Nordin, M. Kowalski +27
Modern time-domain surveys, such as the Zwicky Transient Facility (ZTF), detect far more extragalactic transients than can be spectroscopically classified. Photometric classificati…
Light-Curve and Spectral Properties of Type II Supernovae from the ATLAS survey
K. Ertini, J. P. Anderson, G. Folatelli +22
Type II supernovae (SNe II) are the most common terminal stellar explosions in the Universe. With SNe now being detected within days after explosion, there is growing evidence that…
Narrow absorption lines from intervening material in supernovae: III. Supernovae and their environments
Claudia P. Gutiérrez, Santiago González-Gaitán, Joseph P. Anderson +1
Narrow interstellar absorption features in supernova (SN) spectra serve as valuable diagnostics for probing dust extinction and the presence of circumstellar or interstellar materi…
