Event Horizon Telescope observations of the jet launching and collimation in Centaurus A

Michael Janssen, Heino Falcke, Matthias Kadler +236

Very-long-baseline interferometry (VLBI) observations of active galactic nuclei at millimeter wavelengths have the power to reveal the launching and initial collimation region of e…

Polarimetric properties of Event Horizon Telescope targets from ALMA

Ciriaco Goddi, Ivan Marti-Vidal, Hugo Messias +31

We present the results from a full polarization study carried out with ALMA during the first VLBI campaign, which was conducted in Apr 2017 in the 3mm and 1.3mm bands, in con…

An Intensity Mapping Detection of Aggregate CO Line Emission at 3 mm

Garrett K. Keating, Daniel P. Marrone, Geoffrey C. Bower +1

We present a detection of molecular gas emission at using the technique of line intensity mapping. We make use of a pair of 3 mm interferometric data sets, the first fro…

Micro-arcsecond structure of Sagittarius A* revealed by high-sensitivity 86 GHz VLBI observations

Christiaan D. Brinkerink, Cornelia Müller, Heino D. Falcke +21

The compact radio source Sagittarius~A (Sgr~A)in the Galactic Center is the primary supermassive black hole candidate. General relativistic magnetohydrodynamical (GRMHD) si…

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…
