A long life of excess: The interacting transient SN 2017hcc
S. Moran, M. Fraser, R. Kotak +29
In this study we present the results of a five-year follow-up campaign of the long-lived type IIn supernova SN 2017hcc, found in a spiral dwarf host of near-solar metallicity. The…
Panning for gold, but finding helium: discovery of the ultra-stripped supernova SN2019wxt from gravitational-wave follow-up observations
I. Agudo, L. Amati, T. An +96
We present the results from multi-wavelength observations of a transient discovered during the follow-up of S191213g, a gravitational wave (GW) event reported by the LIGO-Virgo Col…
SN2020qlb: A hydrogen-poor superluminous supernova with well-characterized light curve undulations
S. L. West, R. Lunnan, C. M. B. Omand +21
SN\,2020qlb (ZTF20abobpcb) is a hydrogen-poor superluminous supernova (SLSN-I) that is among the most luminous (maximum M mag) and that has one of the longest rise t…
An elliptical accretion disk following the tidal disruption event AT 2020zso
T. Wevers, M. Nicholl, M. Guolo +25
[Abridged] We classify AT 2020zso as a TDE based on the blackbody evolution inferred from UV/optical photometric observations, and spectral line content and evolution. We identify…
The Hydrogen-Poor Superluminous Supernovae from the Zwicky Transient Facility Phase-I Survey: II. Light Curve Modeling and Characterization of Undulations
Z. H. Chen, Lin Yan, T. Kangas +19
We present analysis of the light curves (LCs) of 77 hydrogen-poor superluminous supernovae (SLSNe-I) discovered during the Zwicky Transient Facility Phase-I operation. We find that…
The Hydrogen-Poor Superluminous Supernovae from the Zwicky Transient Facility Phase-I Survey: I. Light Curves and Measurements
Z. H. Chen, Lin Yan, T. Kangas +40
During the Zwicky Transient Facility (ZTF) Phase-I operation, 78 hydrogen-poor superluminous supernovae (SLSNe-I) were discovered in less than three years, making up the largest sa…
SN 2018bsz: a Type I superluminous supernova with aspherical circumstellar material
M. Pursiainen, G. Leloudas, E. Paraskeva +26
We present a spectroscopic analysis of Type I superluminous supernova (SLSN-I), SN 2018bsz. While it closely resembles SLSNe-I, the multi-component H line appearing at …
