ALMA workshop "Ultra-High Resolution Observation with Phased-ALMA"

Date: January 13-14, 2016

Venue: "Cosmos-Kaikan" meeting room, Mitaka campus of NAOJ.

Language: Talks and slides shall be given in English.

Scope:
ALMA phase-up capability will be offered in ALMA Cycle 4.
This capability will enable us to do VLBI observations with the
spatial resolution better than　100 micro-arcsec and unprecedented
sensitivity at millimeter wavelengths.　Potential scientific targets
are imaging of black hole shadow,　accretion disk, and jet base of
active galactic nuclei.　The main aim of this workshop is to review
the recent progress of　these scientific topics and discuss the
prospects for Cycle 4 and beyond.　All researchers from multi-
wavelength and theoretical communities are welcomed　to join this
workshop.
