The Submillimeter Array SMA News
The Submillimeter Array (SMA) is an 8-element radio interferometer located atop Maunakea in Hawaii. Operating at frequencies from 180 GHz to 418 GHz, the 6m dishes may be arranged into configurations with baselines as long as 509m, producing a synthesized beam of sub-arcsecond width. Each element can observe with two receivers simultaneously, with up to 8 GHz bandwidth each per sideband. The digital correlator backend provides a uniform resolution as high as 140 kHz.

The Submillimeter Array is a joint project between the Smithsonian Astrophysical Observatory and the Academia Sinica Institute of Astronomy and Astrophysics and is funded by the Smithsonian Institution and the Academia Sinica.

February 7, 2018 Call for Projects Proposals - 2018A Semester

We wish to draw your attention to the currrently open call for proposals for observations with the Submillimeter Array (SMA), the reconfigurable interferometric array of eight 6-m antennas on Mauna Kea jointly built and operated by the Smithsonian Astrophysical Observatory and the Academia Sinica Institute of Astronomy and Astrophysics. The array operates in the 230 GHz, 345 GHz and 400 GHz bands. The SMA is currently accepting proposals for the 2018A observing semester (16 May, 2018 - 15 Nov, 2018) from principal investigators from the worldwide astronomical community.
May 16, 2018 - Nov 15, 2018.

January 3, 2018 SMA at the AAS 231st meeting, Washington, DC 8-12 January 2018

The Submillimeter Array (SMA) will be at the 231st AAS meeting in Washington, DC with a special session and an exhibit booth, as well as results presented by individual investigators in various oral and poster sessions. The SMA is in the midst of ambitious upgrade to dramatically improve its observational sensitivity and speed, offering a powerful complement to ALMA. SMA observing time is available to the community on a competitive basis, with two proposal deadlines each year for rapid response.

December 19, 2017 Call for Large Scale and Standard Projects Proposals - 2018A Semester

We wish to draw your attention to the Large Scale Projects program for observations with the Sub-millimeter Array (SMA), which is now accepting Notices of Intent to propose. Under this program, proposals dedicated to answering major astrophysical questions having significant scientific impact requiring observing times of order 100-1000 hours are solicited. In this communication, we are also pre-announcing the dates for standard observing proposals. These calls are for the 2018A semester with observing period
May 16, 2018 - Nov 15, 2018.

December 8, 2017 Dusty protoplanetary disks
"Planetary systems form out of disks of gas and dust around young stars. How the formation proceeds, however, is complex and poorly understood. Many physical processes are involved including accretion onto the star, photoevaporation of material of the disk, interactions of the disk with planetary embryos, growth of the dust grains, settling of the dust to the midplane of the disk, and more. To unravel these various factors, observations of protoplanetary disks at multiple wavelengths are used; the submillimeter wavelength range in particular offers a way to peer through most of the disk to estimate dust masses directly."
