A Chandra observation of the distant radio galaxy B 2 0902 + 343 : a powerful obscured active galaxy
We report a Chandra observation of the z = 3.395 radio galaxy B2 0902+343. The unresolved X-ray source is centred on the active nucleus. The spectrum is well fit by a flat power law of photon index of Γ ∼ 1.1 with intrinsic absorption of 8 × 10 22 cm −2 , and an intrinsic 2– 10 keV luminosity of 3.3 × 10 45 erg s −1. More complex models which allow for a steeper spectral index cause the column ...
متن کاملA Chandra Observation of the Circinus Galaxy
We report on a recent Chandra ACIS-S observation of the Circinus galaxy. These observations confirm that the nuclear spectrum results from reflection of a hard X-ray continuum by “neutral” matter. The nuclear X-ray emission is extended by ∼ 60 pc in the general direction of the optical “ionization cone”. An image in the Fe Kα line has been made and shows that this emission extends up to 200 pc ...
متن کاملA Large-scale Shock Surrounding a Powerful Radio Galaxy
We report the Chandra detection of a large-scale shock, on scales of 200 kpc, in the cluster surrounding the powerful radio galaxy 3C 444 (PKS 2211−17). Our 20-ks Chandra observation allows us to identify a clear surface brightness drop around the outer edge of the radio galaxy, which is likely to correspond to a spheroidal shock propagating into the intracluster medium. We measure a temperatur...
متن کاملChandra Reveals Twin X-ray Jets in the Powerful Fr Ii Radio Galaxy 3c 353
We report X-ray imaging of the powerful FR II radio galaxy 3C 353 using the Chandra X-ray Observatory. 3C 353’s two 4′′-wide and 2′-long jets allow us to study in detail the internal structure of the large-scale relativistic outflows at both radio and X-ray photon energies with the sub-arcsecond spatial resolution provided by the VLA and Chandra instruments. In a 90 ks Chandra observation, we h...
متن کاملChandra Observation of Lmxbs in the Elliptical Galaxy M 84
We present characteristics of the X-ray point source population in the M84 galaxy, observed by Chandra ACIS-S. We find an excess in the number of sources centered on M84, with a spatial distribution closely corresponding to the M84 stellar light. Given an absence of recent star-formation, accreting binaries are the only candidates for the M84 X-ray sources. The majority of M84 sources (with lum...
