A VLBI receiving system for the South Pole Telescope
Junhan Kim, Daniel P. Marrone, Christopher Beaudoin +15
The Event Horizon Telescope (EHT) is a very-long-baseline interferometry (VLBI) experiment that aims to observe supermassive black holes with an angular resolution that is comparab…
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…
Detection of intrinsic source structure at ~3 Schwarzschild radii with Millimeter-VLBI observations of SAGITTARIUS A*
Ru-Sen Lu, Thomas P. Krichbaum, Alan L. Roy +53
We report results from very long baseline interferometric (VLBI) observations of the supermassive black hole in the Galactic center, Sgr A*, at 1.3 mm (230 GHz). The observations w…
