Optical and radio behaviour of the BL Lacertae object 0716+714
C. M. Raiteri, M. Villata, G. Tosti +24
Eight optical and four radio observatories have been intensively monitoring the BL Lac object 0716+714 in the last years: 4854 data points have been collected in the UBVRI bands si…
Compact Intraday Variable Radio Cores: New Observational Approaches
L. Fuhrmann, G. Cimò, T. P. Krichbaum +4
The evidence for refractive interstellar scintillation (RISS) being the main cause for rapid intraday variations (Intraday Variability, IDV) in Quasars and BL Lacs has recently bec…
Multi-frequency Study of Intraday Variable Sources
Giuseppe Cimò, L. Fuhrmann, T. P. Krichbaum +4
Intraday variability (IDV) of compact extragalactic radio sources is a complex phenomenon and shows a wavelength dependent mixture of refractive interstellar scintillation (RISS) (…
A very rapid Extreme Scattering Event in the IDV source 0954+658
G. Cimò, T. Beckert, T. P. Krichbaum +4
Extreme Scattering Events (ESEs) are dramatic variations of the flux density at Gigahertz frequencies caused by ray path distortions within an isolated inhomogeneity ("plasma lens"…
