In lower frequency bands, the East Asia VLBI Network (EAVN) and KaVA are also getting the unprecedented results of jets and accretion flows in M87, Sgr A*, and other AGNs. >From a broader perspective, the co-evolution of the black holes and their host galaxies through the merger of binary black holes and mass accretion is important in the cosmological context and has been intensively studied. Related to these themes, the mass supply mechanism from the circumnuclear region is absolutely essential and recent observation shows some evidence of them. This will potentially enable us to understand its connection to the horizon scale phenomena. Motivated by recent progress of these observations, theory and simulations of magnetohydrodynamics, kinetic plasma physics, and radiative transfer of accretion flows and relativistic jets have been also carried out vigorously and new perceptions have been attained. 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 [in person (for domestic people) and on-line via zoom]. All of the talks and the posters are given by on-line, and participants can also join the workshop on-cite if they hope. (The number of on-site-participants is limited because of the social distancing rule. We can accept only 10 on-site-participants except LOC members. If more than 10 candidates desire to join the workshop in person, we will select the on-site-participants. Thank you for your understanding.) This workshop is supported by the Collaborative Research Program of the Institute for Cosmic Ray Research, the University of Tokyo. ———————— Topics: ———————— Observation, theory and simulation of relativistic jet and accretion flow and accretion flow Physics of black hole magnetosphere Accretion from circumnuclear region Radio observation of compact object and relevant high-energy phenomena Magnetohydrodynamics, kinetic plasma physics, and radiative transfer around the compact objects ———————— Invited speakers ———————— Yuzhu Cui (Sokendai/NAOJ/SJTU) Lei Huang (SHAO) Masatoshi Imanishi (NAOJ) Kyohei Kawaguchi (ICRR) Serguei S.
