Type II supernovae from the Carnegie Supernova Project-I. III. Understanding SN II diversity through correlations between physical and observed properties
L. Martinez, J. P. Anderson, M. C. Bersten +17
SNe II show great photometric and spectroscopic diversity which is attributed to the varied physical characteristics of their progenitor and explosion properties. In this study, th…
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 …
Type II supernovae from the Carnegie Supernova Project-I. I. Bolometric light curves of 74 SNe II using uBgVriYJH photometry
L. Martinez, M. C. Bersten, J. P. Anderson +18
The present study is the first of a series of three papers where we characterise the type II supernovae (SNe~II) from the Carnegie Supernova Project-I to understand their diversity…
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…
Type II supernovae from the Carnegie Supernova Project-I. II. Physical parameter distributions from hydrodynamical modelling
L. Martinez, M. C. Bersten, J. P. Anderson +18
Linking supernovae to their progenitors is a powerful method for furthering our understanding of the physical origin of their observed differences, while at the same time testing s…
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…
Photometric and spectroscopic evolution of the interacting transient AT 2016jbu (Gaia16cfr)
S. J. Brennan, M. Fraser, J. Johansson +68
We present the results from a high cadence, multi-wavelength observation campaign of AT 2016jbu (aka Gaia16cfr), an interacting transient. This dataset complements the current lite…
Observation of bifurcations and hysteresis in experimentally coupled logistic maps
Caracé Gutiérrez, Cecilia Cabeza, Nicolás Rubido
Initially, the logistic map became popular as a simplified model for population growth. In spite of its apparent simplicity, as the population growth-rate is increased the map exhi…
SN 2011A: an low-luminosity interacting transient, with a double plateau and strong sodium absorption
T. de Jaeger, J. P. Anderson, G. Pignata +16
We present optical photometry and spectroscopy of the optical transient SN 2011A. Our data spans 140 days after discovery including photometry and 11 epochs of opt…
Defining Photometric Peculiar Type Ia Supernovae
S. Gonzalez-Gaitan, E. Y. Hsiao, G. Pignata +9
We present a new photometric identification technique for SN 1991bg-like type Ia supernovae (SNe Ia), i.e. objects with light-curve characteristics such as later primary maxima and…
SN2011hs: a Fast and Faint Type IIb Supernova from a Supergiant Progenitor
F. Bufano, G. Pignata, M. Bersten +33
Observations spanning a large wavelength range, from X-ray to radio, of the Type IIb supernova 2011hs are presented, covering its evolution during the first year after explosion. T…
