Towards the Event Horizon - The Vicinity of AGN at Micro-Arcsecond Resolution
T. P. Krichbaum, D. A. Graham, W. Alef +18
We summarize the present status of VLBI experiments at 3 mm (86 GHz), 2 mm (129-150 GHz) and 1.3 mm (215-230 GHz). We present and discuss a new 3 mm VLBI map of M87 (Virgo A), whic…
Millimetre-VLBI Monitoring of AGN with Sub-milliarcsecond Resolution
A. Pagels, T. P. Krichbaum, D. A. Graham +10
Global millimetre VLBI allows detailed studies of the most central jet regions of AGN with unprecedent spatial resolution of a few 100-1000 Schwartzschild radii to be made. Study o…
Models of Polarized and Variable Radio Emission for IDV Source 0917+624
T. Beckert, A. Kraus, T. P. Krichbaum +2
We examine the power spectra of IDV and show the information, which is to be gained by wavelet analysis of light curves of the quasar 0917+624. Results for total and polarized flux…
Unusual radio variability in the BL Lac object 0235+164
A. Kraus, A. Quirrenbach, A. P. Lobanov +11
We present radio observations at three frequencies and contemporaneous optical monitoring of the peculiar BL Lac object AO 0235+164. During a three-week campaign with the VLA we ob…
Radiospectra and kinematics in blazars
A. P. Lobanov, A. Kraus, J. A. Zensus
Broad band spectra of total and compact--scale radio emission from blazars, used in combination with kinematic information inferred from VLBI monitoring programs, can be applied su…
Gamma-ray to radio activity and ejection of a VLBI component in the jet of the S5-quasar 0836+710
K. Otterbein, T. P. Krichbaum, A. Kraus +4
Broad-band (gamma to radio) variations of the flux density were observed in the first half of 1992 in the luminous high redshift (z = 2.172) quasar S5 0836+710. VLBI monitoring obs…
