SN 2020wnt: a slow-evolving carbon-rich superluminous supernova with no O II lines and a bumpy light curve
C. P. Gutiérrez, A. Pastorello, M. Bersten +29
We present the analysis of SN 2020wnt, an unusual hydrogen-poor super-luminous supernova (SLSN-I), at a redshift of 0.032. The light curves of SN 2020wnt are characterised by an ea…
The double-peaked type Ic Supernova 2019cad: another SN 2005bf-like object
C. P. Gutiérrez, M. C. Bersten, M. Orellana +23
We present the photometric and spectroscopic evolution of supernova (SN) 2019cad during the first days from explosion. Based on the light curve morphology, we find that S…
A systematic study of magnetar-powered hydrogen-rich supernovae
Mariana Orellana, Melina Bersten, Takashi Moriya
Context: It has been suggested that some supernovae (SNe) may be powered by a magnetar formed at the moment of the explosion. While this scenario has mostly been applied to hydroge…
A surge of light at the birth of a supernova
M. C. Bersten, G. Folatelli, F. García +18
It is difficult to establish the properties of massive stars that explode as supernovae. The electromagnetic emission during the first minutes to hours after the emergence of the s…
The Unusual Super-Luminous Supernovae SN 2011kl and ASASSN-15lh
Melina C. Bersten, Omar G. Benvenuto, Mariana Orellana +1
Two recently discovered very luminous supernovae (SNe) present stimulating cases to explore the extents of the available theoretical models. SN 2011kl represents the first detectio…
Gamma-ray absorption and the origin of the gamma-ray flare in Cygnus X-1
Gustavo E. Romero, Maria Victoria del Valle, Mariana Orellana
The high-mass microquasar Cygnus X-1, the best-established candidate for a stellar-mass black hole in the Galaxy, has been detected in a flaring state at very high energies (VHE),…
