The Size, Shape, and Scattering of Sagittarius A* at 86 GHz: First VLBI with ALMA
S. Issaoun, M. D. Johnson, L. Blackburn +41
The Galactic Center supermassive black hole Sagittarius A* (Sgr A*) is one of the most promising targets to study the dynamics of black hole accretion and outflow via direct imagin…
Location of Gamma-ray emission and magnetic field strengths in OJ 287
J. A. Hodgson, T. P. Krichbaum, A. P. Marscher +19
The Gamma-ray BL Lac object OJ 287 is known to exhibit inner-parsec "jet-wobbling", high degrees of variability at all wavelengths and quasi-stationary features including an appare…
Zooming towards the Event Horizon - mm-VLBI today and tomorrow
T. P. Krichbaum, A. Roy, J. Wagner +21
Global VLBI imaging at millimeter and sub-millimeter wavelength overcomes the opacity barrier of synchrotron self-absorption in AGN and opens the direct view into sub-pc scale regi…
On the Calibration of Full-polarization 86GHz Global VLBI Observations
I. Marti-Vidal, T. P. Krichbaum, A. Marscher +11
We report the development of a semi-automatic pipeline for the calibration of 86 GHz full-polarization observations performed with the Global Millimeter-VLBI array (GMVA) and descr…
Towards millimeter VLBI
T. P. Krichbaum, U. Bach, D. A. Graham +6
We discuss the present performance and the future perspectives of VLBI in the 3 mm to 0.85 mm observing bands (so called mm-VLBI). The availability of new telescopes and the recent…
