Multi-frequency VLBA study of the blazar S5 0716+714 during the active state in 2004: I. Inner jet kinematics
E. A. Rastorgueva, K. Wiik, T. Savolainen +4
We observed the blazar \object{0716+714} with the VLBA during its active state in 2003-2004. In this paper we discuss multi-frequency analysis of the inner jet (first 1 mas) kinema…
Studying the continuum spectrum of the parsec scale jets by multi-frequency VLBI measurements
T. Savolainen, K. Wiik, E. Valtaoja +1
Multi-frequency VLBI observations allow studies of the continuum spectrum in the different parts of the parsec scale jets of AGN, providing information on the physical properties o…
Orbital periods of cataclysmic variables identified by the SDSS. V. VLT, NTT and Magellan observations of nine equatorial systems
John Southworth, B T Gaensicke, T R Marsh +6
We present VLT and Magellan spectroscopy and NTT photometry of nine faint cataclysmic variables (CVs) which were spectroscopically identified by the SDSS. We measure orbital period…
Ten-year optical monitoring of PKS 0735+178: historical comparison, multiband behaviour and variability timescales
S. Ciprini, L. O. Takalo, G. Tosti +7
New data and results on the optical behaviour of the blazar PKS 0735+178 are presented. In addition the whole historical light curve, and a new photometric calibration of compariso…
Testing the inverse-Compton catastrophe scenario in the intra-day variable blazar S5 0716+71: II. A search for intra-day variability at millimetre wavelengths with the IRAM 30 m telescope
I. Agudo, T. P. Krichbaum, H. Ungerechts +12
We report on a densely time sampled polarimetric flux density monitoring of the BL Lac object S5 0716+71 at 86 GHz and 229 GHz with the IRAM 30 m telescope within a coordinated bro…
HS 0943+1404, a true intermediate polar
P. Rodriguez-Gil, B. T. Gaensicke, H. -J. Hagen +7
We have identified a new intermediate polar, HS 0943+1404, as part of our ongoing search for cataclysmic variables in the Hamburg Quasar Survey. The orbital and white dwarf spin pe…
