The X - ray jet and halo of PKS 0521 − 365
Chandra ACIS observations of PKS 0521−365 find that the X-ray emission of this BL Lac object consists of emission from an unresolved core, a diffuse halo, and a 2 arcsec jet feature coincident with the inner radio/optical jet. A comparison with a new ATCA 8.6-GHz map also finds X-ray emission from the bright hotspot southeast of the nucleus. The jet spectrum, from radio to X-ray, is probably sy...
متن کاملThe Chandra X-ray Observatory Resolves the X-ray Morphology and Spectra of a Jet in Pks 0637-752
The core-dominated radio-loud quasar PKS 0637-752 (z = 0.654) was the first celestial object observed with the Chandra X-ray Observatory, offering the early surprise of the detection of a remarkable X-ray jet. Several observations with a variety of detector configurations contribute to a total exposure time with the Chandra Advanced CCD Imaging Spectrometer (ACIS; Garmire et al. 2000, in prepar...
متن کاملThe XMM - Newton view of the X - ray halo and jet of NGC 6251
We present an XMM-Newton observation of the radio jet and diffuse halo of the nearby radio galaxy NGC 6251. The EPIC spectrum of the galaxy's halo is best-fitted by a thermal model with temperature kT ∼ 1.6 keV and sub-solar abundances. Interestingly, an additional hard X-ray component is required to fit the EPIC spectra of the halo above 3 keV, and is independently confirmed by an archival Cha...
متن کاملThe Galactic X-ray halo
Weanalyzed the intensity distribution of the 3/4 keV and 1/4 keV diffuse soft X-ray background by correlating the ROSAT all-sky survey with the Leiden/Dwingeloo H i survey. We found that the 3/4 keV and 1/4 keV intensity distributions can be modelled by a contribution from an isothermal (kT = 0.135 keV) flattened X-ray halo superposed on the radiation from an extragalactic X-ray background. The...
