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…

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…

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…

SN 2021lwz: Another Exotic Luminous and Fast Evolving Optical Stripped Envelope Supernova ?

F. Poidevin, S. L. West, C. M. B. Omand +25

Current large-scale, high-cadence surveys, such as the ZTF, provide detections of new and rare types of transients and supernovae whose physical origins are not well understood. We…

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…

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…
