Multiwavelength 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 کاملGAMMA RAY PULSARS Multiwavelength Observations
High-energy gamma rays are a valuable tool for studying particle acceleration and radiation in the magnetospheres of energetic pulsars. The seven or more pulsars seen by instruments on the Compton Gamma Ray Observatory (CGRO) show that: the light curves usually have double-peak structures (suggesting a broad cone of emission); gamma rays are frequently the dominant component of the radiated pow...
متن کاملMultiwavelength Observations of Ultraluminous X-Ray Sources
Multiwavelength observations may help us understand the physical nature of the ultraluminous X-ray sources (ULXs) found in external galaxies. Enabled by the arcsecond X-ray source positions now available from Chandra, there has been significant recent progress in the identification of optical and radio counterparts to ULXs. Recent results are reviewed on the identification of optical stellar co...
متن کاملThe Complex VHE And Multiwavelength Flaring Activity
The blazar PKS 1510-089 was the first of the flat spectrum radio quasar type, which had been detected simultaneously by a ground based Cherenkov telescope (H.E.S.S.) and the LAT instrument on board the Fermi satellite. Given the strong broad line region emission defining this blazar class, and the resulting high optical depth for VHE (E > 100 GeV) γ-rays, it was surprising to detect VHE emissio...
متن کاملMultiwavelength Gamma-Ray Bursts Observations with ECLAIRs
ECLAIRs is the next space borne instrument that will be fully dedicated to multiwavelength studies of Gamma-Ray Bursts (GRBs). It consists of a coded mask telescope with a wide (∼2 sr) field of view, made of 6400 CdTe pixels (∼1000 cm2), which will work in the 4– 300 keV energy band. It is expected to localise ∼80 GRBs/yr, thanks to the on-board real time event processing. The GRBs (and other t...
