Extremely energetic supernova explosions embedded in a massive circumstellar medium: the case of SN 2016aps
Akihiro Suzuki, Matt Nicholl, Takashi J. Moriya +1
We perform one-dimensional radiation-hydrodynamic simulations of energetic supernova ejecta colliding with a massive circumstellar medium (CSM) aiming at explaining SN 2016aps, lik…
SN 2017gci: a nearby Type I Superluminous Supernova with a bumpy tail
Achille Fiore, Ting-Wan Chen, Anders Jerkstrand +26
We present and discuss the optical spectro-photometric observations of the nearby (z=0.087) Type I superluminous supernova (SLSN I) SN 2017gci, whose peak K-corrected absolute magn…
Accretion disc cooling and narrow absorption lines in the tidal disruption event AT 2019dsg
G. Cannizzaro, T. Wevers, P. G. Jonker +23
We present the results of a large multi-wavelength follow-up campaign of the Tidal Disruption Event (TDE) \dsg, focusing on low to high resolution optical spectroscopy, X-ray, and…
Creation/destruction of ultra-wide binaries in tidal streams
Jorge Peñarrubia
This paper uses statistical and -body methods to explore a new mechanism to form binary stars with extremely large separations (), whose origin is poorly unders…
A dearth of young and bright massive stars in the Small Magellanic Cloud
A. Schootemeijer, N. Langer, D. Lennon +7
Massive star evolution at low metallicity is closely connected to many fields in high-redshift astrophysics, but poorly understood. The Small Magellanic Cloud (SMC) is a unique lab…
The Origin of the Dust Extinction Curve in Milky Way-like Galaxies
Qi Li, Desika Narayanan, Paul Torrey +2
We develop a cosmological model for the evolution of dust grains in galaxies with a distribution of sizes in order to understand the origin of the Milky Way dust extinction curve.…
