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…
Two years of optical and NIR observations of the superluminous supernova UID 30901 discovered by the UltraVISTA SN survey
Emilio D. Hueichapán, Carlos Contreras V., Regis Cartier +6
We present deep optical and near-infrared photometry of UID 30901, a superluminous supernova (SLSN) discovered during the UltraVISTA survey. The observations were obtained with VIR…
SN 2019hcc: A Type II Supernova Displaying Early O II Lines
Eleonora Parrag, Cosimo Inserra, Steve Schulze +18
We present optical spectroscopy together with ultraviolet, optical and near-infrared photometry of SN 2019hcc, which resides in a host galaxy at redshift 0.044, displaying a sub-so…
Probing the Progenitors of Type Ia Supernovae using Circumstellar Material Interaction Signatures
Peter Clark, Kate Maguire, Mattia Bulla +4
This work aims to study different probes of Type Ia supernova progenitors that have been suggested to be linked to the presence of circumstellar material (CSM). In particular, we h…
Real-time Discovery of AT2020xnd: A Fast, Luminous Ultraviolet Transient with Minimal Radioactive Ejecta
Daniel A. Perley, Anna Y. Q. Ho, Yuhan Yao +29
The many unusual properties of the enigmatic AT2018cow suggested that at least some subset of the empirical class of fast blue optical transients (FBOTs) represents a genuinely new…
The delay time distribution of supernovae from integral-field spectroscopy of nearby galaxies
Asier Castrillo, Yago Ascasibar, Lluís Galbany +6
Constraining the delay-time distribution (DTD) of different supernova (SN) types can shed light on the timescales of galaxy chemical enrichment and feedback processes affecting gal…
