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…
Bright, months-long stellar outbursts announce the explosion of interaction-powered supernovae
Nora L. Strotjohann, Eran O. Ofek, Avishay Gal-Yam +53
Interaction-powered supernovae (SNe) explode within an optically-thick circumstellar medium (CSM) that could be ejected during eruptive events. To identify and characterize such pr…
SN 2019ehk: A Double-Peaked Ca-rich Transient with Luminous X-ray Emission and Shock-Ionized Spectral Features
Wynn V. Jacobson-Galán, Raffaella Margutti, Charles D. Kilpatrick +64
We present panchromatic observations and modeling of the Calcium-rich supernova 2019ehk in the star-forming galaxy M100 (d16.2 Mpc) starting 10 hours after explosion and c…
An outflow powers the optical rise of the nearby, fast-evolving tidal disruption event AT2019qiz
M. Nicholl, T. Wevers, S. R. Oates +42
At 66 Mpc, AT2019qiz is the closest optical tidal disruption event (TDE) to date, with a luminosity intermediate between the bulk of the population and iPTF16fnl. Its proximity all…
The Isaac Newton Telescope monitoring survey of Local Group dwarf galaxies. I. Survey overview and first results for Andromeda I
Elham Saremi, Atefeh Javadi, Jacco Th. van Loon +10
An optical monitoring survey in the nearby dwarf galaxies was carried out with the 2.5-m Isaac Newton Telescope (INT). 55 dwarf galaxies and four isolated globular clusters in the…
The Tidal Disruption Event AT 2018hyz I: Double-peaked emission lines and a flat Balmer decrement
P. Short, M. Nicholl, A. Lawrence +28
We present results from spectroscopic observations of AT 2018hyz, a transient discovered by the ASAS-SN survey at an absolute magnitude of mag, in the nucleus of a…
