VLBA Imaging at 7 mm and Linear Polarimetric Observations at 6 cm and 3 mm of Sagittarius A*
Geoffrey C. Bower, Heino Falcke, Don Backer +1
We summarize the results of 7 mm VLBA imaging of Sgr A* and discuss some of the difficulties of accurately constraining the size of Sgr A* with VLBI observations. Our imaging resul…
VLA and VLBA observations of compact radio cores in LINER galaxies
Heino Falcke, Luis C. Ho, James S. Ulvestad +2
A VLA survey of nearby LINER galaxies at 15 GHz has revealed the presence of a compact radio core in many sources. The cores seem to be correlated with the optical activity. Follow…
H_2O megamaser emission from FR I radio galaxies
C. Henkel, Y. P. Wang, H. Falcke +2
A systematic search for 22 GHz H2O megamaser emission is reported for 50 nearby (z < 0.15) FR I galaxies. No detection was obtained, implying that ultraluminous H2O masers (L_H2O>1…
Jets in AGN -- New Results from HST and VLA
Heino Falcke
This paper summarizes some of our recent projects which try to illuminate the nature and importance of jets associated with active nuclei and compact objects. After a short introdu…
