Chandra X - ray Observations of NGC 1316 ( Fornax A )
2 Abstract We report the results of the Chandra ACIS sub-arcsecond resolution X-ray observation of the archetypal merger radio galaxy NGC 1316 (Fornax A). We confirm the presence of fine sub-structures in the hot Interstellar Medium (ISM). Some of these are likely to result from interaction with the radio jets, while others may be related to a complex intermingling of different phases of the IS...
متن کاملCHANDRA Detection of 16 New X - Ray Sources
We have detected 18 sources over 6 σ threshold within two regions 8 ′ .3×16 ′ .9 and 8 ′ .3×33 ′ .6 in the vicinity of the point with α=03 h 31 m 02 s .45 (J2000) and δ=+43 • 47 ′ 58 ′′ .5 (J2000) using a CHAN DRA ACIS (S+I) observation. Two of the sources were detected before with ROSAT HRI and one source could be closely identified with a star in the optical catalog, USNO A-2. We have also st...
متن کاملInfrared Counterparts to Chandra X-Ray Sources in the Antennae
We use deep J (1.25 μm) and Ks (2.15 μm) images of the Antennae (NGC 4038/9) obtained with the Wide-field InfraRed Camera on the Palomar 200-inch telescope, together with the Chandra X-ray source list of Zezas et al. (2002a), to search for infrared counterparts to X-ray point sources. We establish an Xray/IR astrometric frame tie with ∼ 0. 5 rms residuals over a ∼ 4.3 field. We find 13 “strong”...
متن کاملHot dust in two hard Chandra X - ray sources
The two brightest hard X-ray sources discovered serendipitously by Chandra in the field of the lensing cluster A2390 are found to have ISOCAM counterparts at 6.7 and 15 µm. We use this fact, together with their non-detection by SCUBA at 850 µm, as the basis for DUSTY radiative transfer modelling of their infrared spectral energy distributions. For the best-fitting models, we find that the dust ...
متن کاملOn the Chandra X-ray Sources in the Galactic Center
Recent deep Chandra surveys of the Galactic center region have revealed the existence of a faint, hard X-ray source population. While the nature of this population is unknown, it is likely that several types of stellar objects contribute. For sources involving binary systems, accreting white dwarfs and accreting neutron stars with main sequence companions have been proposed. Among the accreting...
