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…
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 …
Close, bright and boxy: the superluminous SN 2018hti
A. Fiore, S. Benetti, M. Nicholl +37
SN 2018hti was a very nearby (z=0.0614) superluminous supernova with an exceedingly bright absolute magnitude of -21.7 mag in r-band at maximum. The densely sampled pre-maximum lig…
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…
A detailed spectroscopic study of Tidal Disruption Events
P. Charalampopoulos, G. Leloudas, D. B. Malesani +19
Spectroscopically, TDEs are characterized by broad ( 10 km/s) emission lines and show large diversity as well as different line profiles. After carefully and consistently per…
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…
