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…
Multi-messenger astronomy with INTEGRAL
C. Ferrigno, V. Savchenko, A. Coleiro +19
At the time of defining the science objectives of the INTernational Gamma-Ray Astrophysics Laboratory (INTEGRAL), such a rapid and spectacular development of multi-messenger astron…
Optical-Ultraviolet Tidal Disruption Events
Sjoert van Velzen, Thomas W. -S. Holoien, Francesca Onori +2
The existence of optical-ultraviolet Tidal Disruption Events (TDEs) could be considered surprising because their electromagnetic output was originally predicted to be dominated by…
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…
INTEGRAL discovery of a burst with associated radio emission from the magnetar SGR 1935+2154
S. Mereghetti, V. Savchenko, C. Ferrigno +23
We report on INTEGRAL observations of the soft -ray repeater SGR 1935+2154 performed between 2020 April 28 and May 3. Several short bursts with fluence of …
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…
Observational constraints on the optical and near-infrared emission from the neutron star-black hole binary merger S190814bv
K. Ackley, L. Amati, C. Barbieri +151
On 2019 August 14, the LIGO and Virgo interferometers detected a high-significance event labelled S190814bv. Preliminary analysis of the GW data suggests that the event was likely…
Universal bolometric corrections for AGN over 7 luminosity decades
F. Duras, A. Bongiorno, F. Ricci +12
The AGN bolometric correction is a key element to understand BH demographics and compute accurate BH accretion histories from AGN luminosities. However, current estimates still dif…
Extreme variability in an active galactic nucleus: Gaia16aax
G. Cannizzaro, M. Fraser, P. G. Jonker +12
We present the results of a multi-wavelength follow up campaign for the luminous nuclear transient Gaia16aax, which was first identified in January 2016. The transient is spatially…
Evolution of MAXI J1631-479 during the January 2019 outburst observed by INTEGRAL/IBIS
M. Fiocchi, F. Onori, A. Bazzano +8
We report on a recent bright outburst from the new X-ray binary transient MAXI J1631-479, observed in January 2019. In particular, we present the 30-200 keV analysis of spectral tr…
