The nearby He-rich superluminous supernova SN 2021bnw during photospheric phases
A. Fiore, A. Kozyreva, L. Yan +40
Aim. We present and interpret the data of the nearby hydrogen-deficient but helium-rich superluminous supernova SN 2021bnw which reached a magnitude of -20.7 at maximum luminosity…
Relative frequencies of core-collapse supernovae as a function of metallicity: observations vs theoretical predictions
Claudia P. Gutiérrez, LluÃs Galbany, Joseph P. Anderson +4
Understanding supernova (SN) progenitors remains a major challenge in astrophysics, as it involves untangling the complex interplay between stellar physics (e.g., evolution, binari…
Nested, asymmetric H-He circumstellar shells in the Type Icn/Ibn SN 2024abvb
The INTEL Collaboration, J. P. Anderson, C. Aster +17
Interacting transients probe mass loss in the final stages of stellar evolution; however, the geometry and timing of multi-episode mass loss remain poorly constrained. SN 2024abvb…
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…
