A Multiband Approach to AGN: Radioscopy & Radio Astronomy
M. Kadler, E. Ros, J. Kerp +3
Only in the radio-loud population of active galactic nuclei (AGN) does the production, collimation, and acceleration of powerful relativistic jets take place. We introduce here a c…
Combined VLBI- and X-ray Observations of Active Galactic Nuclei
M. Kadler, E. Ros, J. Kerp +2
Compact radio cores in radio-loud active galactic nuclei (AGNs) are classical targets of Very-Long-Baseline interferometric (VLBI) research. Until today little has been known about…
Compact high-velocity clouds around the Galaxy and M31
T. Westmeier, C. Bruens, J. Kerp
We have observed 11 compact high-velocity clouds in the 21-cm line of neutral hydrogen with the 100-m telescope in Effelsberg. Our observations show that most of the clouds have a…
Probes of Jet-Disk-Coupling in AGN from Combined VLBI and X-Ray Observations
M. Kadler, J. Kerp, E. Ros +2
The formation of powerful extragalactic jets is not well understood at present as well as the associated key question:``What makes an AGN radio loud?''. Here we discuss how the com…
Weak lensing study of dark matter filaments and application to the binary cluster A 222 and A 223
J. P. Dietrich, P. Schneider, D. Clowe +2
We present a weak lensing analysis of the double cluster system Abell 222 and Abell 223. The lensing reconstruction shows evidence for a possible dark matter filament connecting bo…
