SMA Image Contest 2009
The Submillimeter Array (SMA) announces its first Image Contest. Much like the
annual NRAO "Radio Astronomy Imaging Contest", the purpose of this contest is
to gather visually compelling images based on SMA data from the SMA user
community to be used for a variety of purposes, including public outreach.
Details here....
The Submillimeter Array (SMA) is an 8-element radio interferometer located atop Mauna Kea in Hawaii. Operating at frequencies from 180 GHz to 700 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 2 GHz bandwidth each. The digital correlator backend allows flexible allocation of thousands of spectral channels to each receiver.
