Fermi /lat Discovery of Gamma-ray Emission from the Flat-spectrum Radio Quasar Pks 1454-354
We report the discovery by the Large Area Telescope (LAT) onboard the Fermi Gamma-ray Space Telescope of high-energy γ−ray (GeV) emission from the flat-spectrum radio quasar PKS 1454-354 (z = 1.424). On 4 September 2008 the source rose to a peak flux of (3.5±0.7)×10 ph cm s (E > 100 MeV) on a time scale of hours and then slowly dropped over the following two days. No significant spectral change...
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-...

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 ...
