Testing the inverse-Compton catastrophe scenario in the intra-day variable blazar S5 0716+71, III. Rapid and correlated flux density variability from radio to sub-mm bands
L. Fuhrmann, T. P. Krichbaum, A. Witzel +22
The BL Lac object S5 0716+71 was observed in a global multi-frequency campaign to search for rapid and correlated flux density variability and signatures of an inverse-Compton (IC)…
6.7 GHz methanol absorption toward the Seyfert 2 galaxy NGC 3079
C. M. V. Impellizzeri, C. Henkel, A. L. Roy +1
The detection of the 6.7 GHz line of methanol (CH3OH) is reported for the first time toward an object beyond the Magellanic Clouds. Using the Effelsberg 100 m telescope, two absorp…
Space VLBI polarimetry of IDV sources: Lessons from VSOP and prospects for VSOP2
U. Bach, T. P. Krichbaum, S. Bernhart +5
To locate and image the compact emission regions in quasars, which are closely connected to the phenomenon of IntraDay Variability (IDV), space VLBI observations are of prime impor…
