Fast blue optical transients (FBOTs) represent one of the most exotic astrophysical transients, exhibiting unusually strong emission across X-ray, optical, and radio wavelengths. T…
SN 2024abfl: A Low-Luminosity Type IIP Supernova in NGC 2146 from a Low-Mass Red Supergiant Progenitor
Xiaohan Chen, Ning-Chen Sun, Qiang Xi +44
Type IIP supernovae (SNe IIP) exhibit a significant diversity in their explosion properties, yet the physical mechanisms driving this diversity remain unknown. In this work, we pre…

SN 2023taz: Implications for the UV Diversity of Superluminous Supernovae
Aysha Aamer, Matt Nicholl, Charlotte Angus +21
Superluminous supernovae (SLSNe) are some of the brightest explosions in the Universe representing the extremes of stellar deaths. At the upper end of their distribution is SN\,202…
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…
Cosmology with supernova Encore in the strong lensing cluster MACS J0138-2155: Time delays & Hubble constant measurement
J. D. R. Pierel, E. E. Hayes, M. Millon +26
Multiply-imaged supernovae (SNe) provide a novel means of constraining the Hubble constant (). Such measurements require a combination of precise models of the lensing mass di…
SN 2024aecx: a fast-evolving Type IIb supernova with a prominent shock-cooling peak
Qiang Xi, Ning-Chen Sun, David Aguado +36
SN 2024aecx is a nearby (11 Mpc) Type IIb SN discovered within 1 d after explosion. In this paper we report high-cadence photometric (typically 0.51 day) and spec…
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…
An extremely soft and weak fast X-ray transient associated with a luminous supernova
W. -X. Li, Z. -P. Zhu, X. -Z. Zou +101
Long gamma-ray bursts (LGRBs), including their subclasses of low-luminosity GRBs (LL-GRBs) and X-ray flashes (XRFs) characterized by low spectral peak energies, are known to be ass…
Eruptive mass loss less than a year before the explosion of superluminous supernovae: I. The cases of SN 2020xga and SN 2022xgc
