Space-VLBI polarimetry of the BL Lac object S5 0716+714: Rapid polarization variability in the VLBI core
To determine the location of the intra-day variable (IDV) emission region within the jet of the BL Lac object S5 0716+714, a multi-epoch VSOP polarization experiment was performed in Autumn 2000. To detect, image, and monitor the short term variability of the source, three space-VLBI experiments were performed with VSOP at 5 GHz, separated in time by six days and by one day. Quasi-contemporaneo...
متن کاملUnusual radio variability in the BL Lac object 0235 + 164
We present radio observations at three frequencies and contemporaneous optical monitoring of the peculiar BLLac object AO0235+164. During a three-week campaign with the VLA we observed intraday variability in this source and found a distinct peak which can be identified throughout the radio frequencies and tentatively connected to the R-band variations. This event is characterized by unusual pr...
متن کاملThe BL Lac objects OQ 530 and S 5 0716 + 714 Simultaneous observations in the X – rays , radio , optical and TeV bands
We present the results of the BeppoSAX observations of two BL Lacs, OQ 530 and S5 0716+714, as part of a ToO program for the simultaneous observation at radio, optical, X–ray and TeV energies. Both sources are detected in the LECS and MECS, with S5 0716+714 visible also in the PDS band, up to about ∼ 60 keV. The X-ray spectra of both sources are better fitted by a double power–law model, with a...
متن کاملOptical imaging and spectroscopy of BL Lac objects
We present optical images and spectroscopy for a dozen of BL Lac objects. Most of these objects were not previously studied and we give for the first time the properties of their host galaxies. The properties of the new host galaxies are generally consistent with those derived in previous optical studies. We found a case (1101-23) where the external isophotes of the galaxy are clearly boxy. In ...
متن کاملRadioband Variability Properties of BL Lac Objects
Centimeter-wavelength total ux density and linear polarization observations have quantiied the high levels of activity in BL Lac objects and identiied variability timescales ranging from < 1 day to several years. Nearly two decades of single-antenna (UMRAO) observations of a ux-limited sample show that the radioband spectra of the total ux are characteristically at even during this activity: th...
