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…
Persistent Asymmetric Structure of Sagittarius A* on Event Horizon Scales
Vincent L. Fish, Michael D. Johnson, Sheperd S. Doeleman +69
The Galactic Center black hole Sagittarius A* (Sgr A*) is a prime observing target for the Event Horizon Telescope (EHT), which can resolve the 1.3 mm emission from this source on…
First 230 GHz VLBI Fringes on 3C 279 using the APEX Telescope
J. Wagner, A. L. Roy, T. P. Krichbaum +52
We report about a 230 GHz very long baseline interferometry (VLBI) fringe finder observation of blazar 3C 279 with the APEX telescope in Chile, the phased submillimeter array (SMA)…
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…
1.3 mm Wavelength VLBI of Sagittarius A*: Detection of Time-Variable Emission on Event Horizon Scales
Vincent L. Fish, Sheperd S. Doeleman, Christopher Beaudoin +27
Sagittarius A*, the ~4 x 10^6 solar mass black hole candidate at the Galactic Center, can be studied on Schwarzschild radius scales with (sub)millimeter wavelength Very Long Baseli…
Imaging an Event Horizon: submm-VLBI of a Super Massive Black Hole
Sheperd Doeleman, Eric Agol, Don Backer +20
A long standing goal in astrophysics is to directly observe the immediate environment of a black hole with angular resolution comparable to the event horizon. Realizing this goal w…
