Experimental Indicators of Accretion Processes in Active Galactic Nuclei
A. Eckart, M. Valencia-S., B. Shahzamanian +19
Bright Active Galactic Nuclei are powered by accretion of mass onto the super massive black holes at the centers of the host galaxies. For fainter objects star formation may signif…
3 mm GMVA Observations of Total and Polarized Emission from Blazar and Radio Galaxy Core Regions
Carolina Casadio, Thomas P. Krichbaum, Alan P. Marscher +7
We present total and linearly polarized 3 mm Global mm-VLBI Array images of a sample of blazars and radio galaxies from the VLBA-BU-BLAZAR 7 mm monitoring program designed to probe…
Nuclear Activity and the Conditions of Star-formation at the Galactic Center
A. Eckart, M. Valencia-S., B. Shahzamanian +15
The Galactic Center is the closest galactic nucleus that can be studied with unprecedented angular resolution and sensitivity. We summarize recent basic observational results on Sa…
Molecular gas in the immediate vicinity of Sgr A* seen with ALMA
Lydia Moser, Álvaro Sánchez-Monge, Andreas Eckart +9
We report serendipitous detections of line emission with ALMA in band 3, 6, and 7 in the central parsec of the Galactic center at an up to now highest resolution (<0.7''). Among th…
