Minutes-duration Optical Flares with Supernova Luminosities

Anna Y. Q. Ho, Daniel A. Perley, Ping Chen +74

In recent years, certain luminous extragalactic optical transients have been observed to last only a few days. Their short observed duration implies a different powering mechanism…

Resolving the explosion of supernova 2023ixf in Messier 101 within its complex circumstellar environment

E. A. Zimmerman, I. Irani, P. Chen +54

Observing a supernova explosion shortly after it occurs can reveal important information about the physics of stellar explosions and the nature of the progenitor stars of supernova…

Monthly quasi-periodic eruptions from repeated stellar disruption by a massive black hole

P. A. Evans, C. J. Nixon, S. Campana +12

In recent years, searches of archival X-ray data have revealed galaxies exhibiting nuclear quasi-periodic eruptions with periods of several hours. These are reminiscent of the tida…

Late time HST UV and optical observations of AT~2018cow: extracting a cow from its background

Anne Inkenhaag, Peter G. Jonker, Andrew J. Levan +4

The bright, blue, rapidly evolving AT2018cow is a well-studied peculiar extragalactic transient. Despite an abundance of multi-wavelength data, there still is no consensus on the n…

SN 2022joj: A Peculiar Type Ia Supernova Possibly Driven by an Asymmetric Helium-shell Double Detonation

Chang Liu, Adam A. Miller, Samuel J. Boos +28

We present observations of SN 2022joj, a peculiar Type Ia supernova (SN Ia) discovered by the Zwicky Transient Facility (ZTF). SN 2022joj exhibits an unusually red $g_\mathrm{ZTF}-…

Probing pre-supernova mass loss in double-peaked Type Ibc supernovae from the Zwicky Transient Facility

Kaustav K. Das, Mansi M. Kasliwal, Jesper Sollerman +34

Eruptive mass loss of massive stars prior to supernova (SN) explosion is key to understanding their evolution and end fate. An observational signature of pre-SN mass loss is the de…

1100 days in the life of the supernova 2018ibb -- The best pair-instability supernova candidate, to date

Steve Schulze, Claes Fransson, Alexandra Kozyreva +63

Abridged - Stars with ZAMS masses between 140 and are thought to explode as pair-instability supernovae (PISNe). During their thermonuclear runaway, PISNe can produce…

SN 2020udy: a SN Iax with strict limits on interaction consistent with a helium-star companion

Kate Maguire, Mark R. Magee, Giorgos Leloudas +24

Early observations of transient explosions can provide vital clues to their progenitor origins. In this paper we present the nearby Type Iax (02cx-like) supernova (SN), SN 2020udy…

A long-duration gamma-ray burst of dynamical origin from the nucleus of an ancient galaxy

Andrew J. Levan, Daniele B. Malesani, Benjamin P. Gompertz +29

The majority of long duration ( s) gamma-ray bursts (GRBs) are believed to arise from the collapse of massive stars \cite{Hjorth+03}, with a small proportion created from the m…
