Abstract

The Submillimeter Array (SMA) has provided forefront capabilities for high spatial and spectral resolution observations at submillimeter wavelengths from its excellent site on Mauna Kea, Hawaii since 2004. SMA observations have resulted in new insights into a wide variety of astrophysical phenomena, from protoplanetary disks to high redshift galaxies. The much larger international Atacama Large Millimeter/submillimeter Array (ALMA) is now in routine operation at millimeter and submillimeter wavelengths. To maintain a leading role in the ALMA era, the SMA project has embarked on an ambitious, staged, strategic upgrade to dramatically improve its sensitivity and observing speed. The new wideband SMA -- the wSMA -- will be ideally suited to spectral line surveys and studies of submillimeter sources in the time domain, as well as a wealth of other applications. This workshop will provide a forum for astronomers from the SMA collaboration and user community to promote, discuss, and elaborate key science cases for wSMA observations in the next decade. The workshop will also facilitate the forging of collaborations to help realize these new science opportunities.
