The possibility of detecting Sagittarius A* at 8.6 mum
R. Schoedel, A. Eckart, K. Muzic +3
The Galactic Center was observed at 8.6 mum in order to detect a mid-infrared (MIR) counterpart of Sgr A*, parallel to NIR observations. The goal was to set constraints on possible…
The Rotation Measure and 3.5mm Polarization of Sgr A*
Jean-Pierre Macquart, Geoffrey C. Bower, Melvyn C. H. Wright +2
We report the detection of variable linear polarization from Sgr A* at a wavelength of 3.5mm, the longest wavelength yet at which a detection has been made. The mean polarization i…
Radio Linear and Circular Polarization from M81*
Andreas Brunthaler, Geoffrey C. Bower, Heino Falcke
We present results from archival Very Large Array (VLA) data and new VLA observations to investigate the long term behavior of the circular polarization of M81*, the nuclear radio…
