Abstract and Registration DEADLINE: December 2nd (Fri), 2016




Formation mechanism of relativistic jets in AGNs is a longstanding problem in astrophysics. Motivated by new exciting results recently obtained by VLBI and comprehensive multi-wavelength studies of AGN jets (from radio to gamma rays), we are organizing a workshop aiming at

  1. presenting observational/theoretical progress and clarifying current challenges of AGN jets, and
  2. having a variety of discussions and exchanging ideas to move forward.

On 17 Jan., we will start from a joint-session of "Introduction to black bole (BH) shadow". In this session, we invite two lecturers as follows:

H. Pu (ASIAA) "Introduction to BH shadow"
K. Akiyama (MIT) "Introduction to BH shadow imaging"

In the workshop (18-20 Jan.), we will address the following topics:

1. JET FUNDAMENTAL
Can jets be explained by Blandford-Znajek model?
What's the origin of spine-structures?
Dissipative Poynting flows? reconnection vs shock?

2. PURSUIT OF ACCRETION FLOWS AND CIRCUMNUCLEAR MEDIUM
Can we see G2-disturbance in Sgr A*?
Accretion flow properties in M87?
Dense circumnuclear medium in 3C84 (NGC1275)?

3. NEW RADIO SURVEYS
Is the "blazar-sequence" universal?
Radio emission properties at mm/submm domain?

Also, we will have a session in which we will discuss topics linked to sub-mm VLBI with phased-ALMA heading for ALMA cyc 5 proposal.


Keynote talks by theoreticians are also planned.
