[85.05] Submillimeter Masers

E. M. L. Humphreys (Harvard-Smithsonian CfA)

Submillimeter masers of several species lie in the frequency range of the SMA (e.g., SiO, H2O, H recombination masers.) With angular resolutions of up to 0.2" at 650 GHz, the SMA can provide unprecedented information on the (sub)-arcsecond scale structure of the masers, and thereby on source dynamics, physical conditions and magnetic fields.

In this talk I will highlight some of the exciting new maser results coming out of the SMA. These include the imaging of the 321 GHz H2O masers of Cepheus A, the first ever arcsecond-resolution maps of 325 GHz H2O masers towards a star-forming region (Orion-KL), the H recombination masers of MWC349, SiO maser polarization in VY CMa and the first detection of an extragalactic millimeter/submillimeter H2O maser, at 183 GHz.
