The hydrogen-free circumstellar interaction in the Type Ib supernova 2021efd: A clue to the mechanism of the helium-layer stripping
N. Pyykkinen, T. Nagao, H. Kuncarayakti +27
Stripped-envelope supernovae (SESNe), including Type IIb, Ib, and Ic supernovae (SNe), originate from the explosions of massive stars whose outer envelopes have been largely remove…
XSNAP: An X-ray Supernova Analysis Pipeline with Application to the Type II Supernova 2024ggi
Ferdinand, W. V. Jacobson-Galán, M. M. Kasliwal +1
X-ray observations of Type II supernovae (SNe II) probe the physics of supernova (SN) shocks and the mass-loss histories of their progenitor stars. We present multi-epoch, X-ray ob…
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…
Luminous, rapidly declining supernovae as stripped transitional objects in low metallicity environments: the case of SN 2022lxg
P. Charalampopoulos, R. Kotak, J. Sollerman +24
We present an analysis of the optical and near-infrared properties of SN 2022lxg, a bright ( mag) and rapidly evolving SN. It was discovered withi…
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…
