The Atacama Large Millimeter/Submillimeter Array (ALMA) is now the most powerful mm/submm interferometer in the world, and it is producing a total of > 500 refereed papers in nearly all fields of astronomy and astrophysics. In particular, the ~0.02” submm images obtained during the long baseline campaign in 2014 (ALMA Partnership et al. 2015) have led to numerous publication and followup observational and theoretical studies, signifying the extreme importance of the high resolution imaging capabilities of ALMA.  

The scope of this workshop is to (1) review the high-resolution ALMA science results obtained to date, (2) identify detailed science cases for the future baseline expansion of ALMA (e.g. aiming at an angular resolution of 0.001”-0.003"), (3) discuss the scientific and technical requirements such as, for example, angular resolution, number and size of the antennas, sensitivity and operational frequency, and (4) review the technical feasibility studies for longer baseline imaging. We envision the output of this workshop to be used as a guideline to pave the pathway for the future expansion of ALMA.

We will have slots available for contributed talks related to the long baseline science and technical aspects pertaining to the expansion of the longest baselines. We will also have space for poster presentations.
