SN 2021adxl: A luminous nearby interacting supernova in an extremely low metallicity environment
S. J. Brennan, S. Schulze, R. Lunnan +17
SN 2021adxl is a slowly evolving, luminous, Type IIn supernova with asymmetric emission line profiles, similar to the well-studied SN 2010jl. We present extensive optical, near-ult…
SN 2020zbf: A fast-rising hydrogen-poor superluminous supernova with strong carbon lines
A. Gkini, R. Lunnan, S. Schulze +24
SN\,2020zbf is a hydrogen-poor superluminous supernova (SLSN) at that shows conspicuous \ion{C}{II} features at early times, in contrast to the majority of H-poor SLSN…
Rapidly Evolving Transients in Archival ZTF Public Alerts
Wenxiong Li, Iair Arcavi, Ehud Nakar +7
We search the archival Zwicky Transient Facility public survey for rapidly evolving transient (RET) candidates based on well-defined criteria between 2018 May and 2021 December. Th…
Photometric study of the late-time near-infrared plateau in Type Ia supernovae
M. Deckers, O. Graur, K. Maguire +23
We present an in-depth study of the late-time near-infrared plateau in Type Ia supernovae (SNe Ia), which occurs between 70-500 d. We double the existing sample of SNe Ia observed…
The Birth of a Relativistic Jet Following the Disruption of a Star by a Cosmological Black Hole
Dheeraj R. Pasham, Matteo Lucchini, Tanmoy Laskar +63
A black hole can launch a powerful relativistic jet after it tidally disrupts a star. If this jet fortuitously aligns with our line of sight, the overall brightness is Doppler boos…
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…
The impostor revealed: SN 2016jbu was a terminal explosion
S. J. Brennan, N. Elias-Rosa, M. Fraser +2
In this letter, we present recent observations from the Hubble Space Telescope of the interacting transient, SN 2016jbu, at +5 years. We find no evidence for any additional outburs…
Probing for the host galaxies of the fast X-ray transients XRT 000519 and XRT 110103
D. Eappachen, P. G. Jonker, M. Fraser +13
Over the past few years, 30 extragalactic fast X-ray transients (FXRTs) have been discovered, mainly in Chandra and XMM-Newton data. Their nature remains unclear, with propos…
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 …
How low can you go? SN 2018zd as a low-mass Fe core-collapse supernova
E. Callis, M. Fraser, A. Pastorello +38
We present spectroscopy and photometry of SN 2018zd, a Type IIP core-collapse supernova with signatures of interaction with circumstantial material in its earliest spectra. High io…
SN 2018bsz: significant dust formation in a nearby superluminous supernova
T. -W. Chen, S. J. Brennan, R. Wesson +41
We investigate the thermal emission and the extinction from dust associated with the nearby (z = 0.0267) superluminous supernova (SLSN) 2018bsz. Our dataset combines daily-cadence,…
Progenitor, environment, and modelling of the interacting transient, AT 2016jbu (Gaia16cfr)
S. J. Brennan, M. Fraser, J. Johansson +67
We present the bolometric lightcurve, identification and analysis of the progenitor candidate, and preliminary modelling of AT2016jbu (Gaia16cfr). We find a progenitor consistent w…
The transitional gap transient AT 2018hso: new insights on the luminous red nova phenomenon
Y-Z. Cai, A. Pastorello, M. Fraser +20
Aims: AT 2018hso is a new transient showing transitional properties between those of LRNe and the class of intermediate luminosity red transients (ILRTs) similar to SN 2008S. Throu…
