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)…
High-resolution double morphology of the most distant known radio quasar at z=6.12
S. Frey, L. I. Gurvits, Z. Paragi +1
Context: The highest redshift quasars at z>~6 receive considerable attention since they provide strong constraints on the growth of the earliest supermassive black holes. They also…
Potential Targets for ASTRO-G In-Beam Phase-Referencing
S. Frey, K. E. Gabanyi
We show that as many as ~50 quasars with at least mJy-level expected flux density can be pre-selected as potential in-beam phase-reference targets for ASTRO-G. Most of them have ne…
J1128+592: a highly variable IDV source
K. E. Gabanyi, N. Marchili, T. P. Krichbaum +9
Short time-scale radio variations of compact extragalactic radio quasars and blazars known as IntraDay Variability (IDV) can be explained in at least some sources as a propagation…
The IDV source J1128+5925, a new candidate for annual modulation?
K. E. Gabanyi, N. Marchili, T. P. Krichbaum +9
Short time-scale radio variations of compact extragalactic radio sources, known as IntraDay Variability, can be explained in at least some sources by a source-extrinsic effect, in…
Testing the inverse-Compton catastrophe scenario in the intra-day variable blazar S5 0716+71. I. Simultaneous broadband observations during November 2003
L. Ostorero, S. J. Wagner, J. Gracia +6
Some intra-day variable, compact extra-galactic radio sources show brightness temperatures severely exceeding 10^{12} K, the limit set by catastrophic inverse-Compton (IC) cooling…
