The detection of the black hole shadow in M87 by the Event Horizon Telescope (EHT) observations provided us powerful evidence of the presence of supermassive black holes. The big and fundamental questions, however, still remain: the magnitude and orientation of the black hole spin, physics of accretion flows, formation mechanism of relativistic jets, cosmic-ray acceleration, and associated gamma-ray and neutrino emission, etc. In order to address these key questions, the VLBI observations with higher resolution and the multi-wavelength/multi-messenger observation will be strong tools.

The workshop will bring researchers working on observation and theory/simulations to discuss our present understanding and key questions towards the future of the spacetime of black holes, the physics of accretion flow, jets, winds, and the related high energy phenomena around compact objects.

Due to the situation of the COVID-19, the workshop will be a hybrid-type (i.e., on-line and on-site, simultaneously). All of the talks and the posters are given by on-line, and participants can also join the workshop on-cite if they hope (but the number of on-site-participants is limited because of the social distancing rule).

This workshop is supported by the Collaborative Research Program of the Institute for Cosmic Ray Research, the University of Tokyo.
