The flare activity of Sagittarius A*
(EDP Sciences, 2006)
Context. We report new simultaneous near-infrared/sub-millimeter/X-ray observations of the SgrA* counterpart associated with the massive 3–4×106M⊙ black hole at the Galactic Center. Aims. The main aim is to investigate the ...
Interferometric Measurements of Variable 340 GHz Linear Polarization in Sagittarius A*
(IOP Publishing, 2006)
Using the Submillimeter Array, we have made the first high angular resolution measurements of the linear polarization of Sagittarius A* at submillimeter wavelengths, and the first detection of intra-day variability in its ...
An Unambiguous Detection of Faraday Rotation in Sagittarius A*
(IOP Publishing, 2006)
The millimeter/submillimeter wavelength polarization of Sgr A* is known to be variable in both magnitude and position angle on time scales down to a few hours. The unstable polarization has prevented measurements made at ...
