Optical Monitoring of PKS 1510−089: A Binary Black Hole System?
Three deep flux minima were observed with nearly the same time-scales and intervals for the blazar PKS 1510−089 in the past few years. A binary black hole system was proposed to be at the nucleus of this object, and a new minimum was predicted to occur in 2002 March. We monitored this source with a 60/90 cm Schmidt telescope from 2002 February to April. In combination with the data obtained by ...

متن کاملAGILE detection of a rapid γ - ray flare from the blazar PKS 1510 - 089 during the GASP - WEBT monitoring ⋆
Context. We report the detection by the AGILE satellite of a rapid γ-ray flare from the source 1AGL J1511−0908, associated with the powerful γ-ray quasar PKS 1510−089, during a pointing centered on the Galactic Center region from 1 March to 30 March 2008. This source has been continuosly monitored in the radio-to-optical bands by the GLAST-AGILE Support Program (GASP) of the Whole Earth Blazar ...
متن کاملPks 1510−089: a Head-on View of a Relativistic Jet
The gamma-ray blazar PKS 1510−089 has a highly superluminal milli-arcsecond jet at a position angle (PA) of −28 and an arcsecond jet with an initial PA of 155. With a ∆PA of 177 between the arcsecond and milliarcsecond jets, PKS 1510−089 is perhaps the most highly misaligned radio jet ever observed and serves as a graphic example of projection effects in a highly beamed relativistic jet. Here w...
متن کاملMultiwavelength Observations of the Powerful γ-ray Quasar PKS 1510−089: Clues on the Jet Composition
We present the results from a multiwavelength campaign conducted in August 2006 of the powerful γ-ray quasar PKS 1510−089 (z = 0.361). This campaign commenced with a deep Suzaku observation lasting three days for a total exposure time of 120 ks, and continued with Swift monitoring over 18 days. Besides Swift observations, which sampled the optical/UV flux in all 6 UVOT filters as well as the X-...
