Variable Linear Polarization from Sagittarius A*: Evidence for a Hot Turbulent Accretion Flow
Geoffrey C. Bower, Heino Falcke, Melvyn C. H. Wright +1
We report the discovery of variability in the linear polarization from the Galactic Center black hole source, Sagittarius A*. New polarimetry obtained with the Berkeley-Illinois-Ma…
Detection of 21 Centimeter HI Absorption at z = 0.78 in a Survey of Radio Continuum Sources
Jeremy Darling, Riccardo Giovanelli, Martha P. Haynes +2
We report the detection of a deep broad HI 21 cm absorption system at z = 0.78 toward the radio source [HB89] 2351+456 (4C+45.51) at z = 1.992. The HI absorption was identified in…
Detection of the Intrinsic Size of Sagittarius A* through Closure Amplitude Imaging (includes Online Supporting Material)
Geoffrey C. Bower, Heino Falcke, Robeson M. Herrnstein +3
We have detected the intrinsic size of Sagittarius A*, the Galactic Center radio source associated with a supermassive black hole, showing that the short-wavelength radio emission…
A Radio Outburst Nearly Coincident with the Large X-ray Flare from Sgr A* on 2002-10-03
Jun-Hui Zhao, R. M. Herrnstein, G. C. Bower +2
A large radio outburst from Sgr A* was observed during the VLA weekly monitoring program at 2 cm, 1.3 cm and 7 mm, nearly coincident with the brightest X-ray flare detected to date…
