The Submillimeter Array Polarimeter
Daniel P. Marrone, Ramprasad Rao
We describe the Submillimeter Array (SMA) Polarimeter, a polarization converter and feed multiplexer installed on the SMA. The polarimeter uses narrow-band quarter-wave plates to g…
SMA Imaging of the Maser Emission from the H30 Radio Recombination Line in MWC349A
Jonathan Weintroub, James M. Moran, David J. Wilner +3
We used the Submillimeter Array to map the angular distribution of the H30 recombination line (231.9 GHz) in the circumstellar region of the peculiar star MWC349A. The resolutio…
Magnetic Fields in the Formation of Sun-Like Stars
Josep M. Girart, Ramprasad Rao, Daniel P. Marrone
We report high-angular-resolution measurements of polarized dust emission toward the low-mass protostellar system NGC 1333 IRAS 4A. We show that in this system the observed magneti…
The Flare Activity of SgrA*; New Coordinated mm to X-Ray Observations
A. Eckart, F. K. Baganoff, R. Schoedel +17
We report new simultaneous near-infrared/sub-millimeter/X-ray observations of the SgrA* counterpart associated with the massive 3-4x10**6 solar mass black hole at the Galactic Cent…
Evidence for a high energy curvature in the XMM-Newton spectrum of the ULX NGC1313 X-1
G. C. Dewangan, R. E. Griffiths, A. R. Rao
ASCA X-ray spectra of many ULXs were described in terms of optically thick emission from hot (kT ~1-2keV) accretion disks, while recent XMM-Newton and Chandra observations have rev…
Sub-arcsecond sub-mm continuum observations of Orion-KL
H. Beuther, Q. Zhang, L. J. Greenhill +9
We present the first 865 mu continuum image with sub-arcsecond resolution obtained with the Submillimeter Array. These data resolve the Orion-KL region into the hot core, the nearb…
