SN 2024afyu interpreted as a Pair Instability Supernova
P. J. Pessi, S. Barmentloo, Ł. Wyrzykowski +63
Pair-instability supernovae (PISNe) are the predicted explosions of very massive stars triggered by electron-positron pair production. Numerous transients have been proposed as PIS…
Eruptive mass loss less than a year before the explosion of superluminous supernovae. II. A systematic search for pre-explosion eruptions with VLT/X-shooter
A. Gkini, C. Fransson, R. Lunnan +22
We present X-shooter observations of a sample of 21 hydrogen-poor superluminous supernovae (SLSNe-I), spanning a redshift range of z=0.13-0.95, aimed at searching for shells of cir…
The ambiguous AT2022rze: Changing-look AGN mimicking a supernova in a merging galaxy system
P. J. Pessi, R. Lunnan, J. Sollerman +36
AT2022rze is a luminous, ambiguous transient located South-East of the geometric center of its host galaxy at redshift z = 0.08. The host appears to be formed by a merging galaxy s…
Precursor Activity Preceding Interacting Supernovae I: Bridging the Gap with SN 2022mop
S. J. Brennan, S. Barmentloo, S. Schulze +41
Over the past two decades, an increasing number of transients have shown luminous activity at their explosion sites weeks to years before an interacting supernova (SN) is observed.…
Eruptive mass loss less than a year before the explosion of superluminous supernovae: I. The cases of SN 2020xga and SN 2022xgc
A. Gkini, C. Fransson, R. Lunnan +47
We present photometric and spectroscopic observations of SN 2020xga and SN 2022xgc, two hydrogen-poor superluminous supernovae (SLSNe-I) at and , respectiv…
Spectroscopic observations of progenitor activity 100 days before a Type Ibn supernova
S. J. Brennan, J. Sollerman, I. Irani +30
Obtaining spectroscopic observations of the progenitors of core-collapse supernovae is often unfeasible due to an inherent lack of knowledge as to which stars will go supernova and…
