The 1.4 mm core of Centaurus A: First VLBI results with the South Pole Telescope
Junhan Kim, Daniel P. Marrone, Alan L. Roy +27
Centaurus A (Cen A) is a bright radio source associated with the nearby galaxy NGC 5128 where high-resolution radio observations can probe the jet at scales of less than a light-da…
Resolved Magnetic-Field Structure and Variability Near the Event Horizon of Sagittarius A*
Michael D. Johnson, Vincent L. Fish, Sheperd S. Doeleman +45
Near a black hole, differential rotation of a magnetized accretion disk is thought to produce an instability that amplifies weak magnetic fields, driving accretion and outflow. The…
Jet Launching Structure Resolved Near the Supermassive Black Hole in M87
Sheperd S. Doeleman, Vincent L. Fish, David E. Schenck +30
Approximately 10% of active galactic nuclei exhibit relativistic jets, which are powered by accretion of matter onto super massive black holes. While the measured width profiles of…
