Special Session SS4  24 June 2019

Multi-wavelength view of transient events in galactic nuclei

Aims and scope

The Special Session on multi-wavelength view of transient events in galactic nuclei aims at gathering together researchers with expertise of phenomena including supernovae (SNe), tidal disruption events (TDEs) and changing look active galactic nuclei (AGN) over a range of wavelengths from radio, infrared, optical, UV and X-rays. This will include experts on a range of techniques from optical spectroscopy to interferometric radio observations providing high angular-resolution, as well as theoreticians to explain the state of the art of current models. The session will therefore consist of presentations and posters providing a multi-wavelength view of nuclear transients, highlighting some intriguing individual cases and also possible explanations for the recently discovered extremely energetic nuclear outbursts. In preparation for the next generation of telescopes, the session will address current observational challenges and needs, such as increasing the number of nearby well studied events, new techniques (e.g. spatially resolved radio observations) and clues for resolving the true nature of the nuclear activity.
