Egret Observations of Gamma Rays from Point Sources with Galactic Latitude +10 < B < +40
The EGRET instrument aboard the Compton Gamma Ray Observatory (CGRO) has completed the rst all-sky survey in high-energy gamma rays and has repeatedly viewed selected portions of the sky. Analysis of the region with galactic latitude +10 < b < +40 indicates the presence of nineteen point sources, including nine which can be identiied as active galactic nuclei, some of which have been reported p...
متن کاملA Statistical Analysis of Point-like Sources in Chandra Galactic Center Survey
Chandra Galactic Center Survey detected nearly 1000 X-ray point-like sources in the 2×0.8 sky region around the Galactic Center. The corresponding area is about 280 × 110 pc at a distance of 8 kpc. In this paper, we study the spatial and luminosity distributions of these sources according to their spectral properties. Eighteen bright sources detected are used to fit jointly an absorbed power-la...
متن کاملStatistical Analysis of Point-like Sources in Chandra Galactic Center Survey
Chandra Galactic Center Survey detected ∼ 800 X-ray pointlike sources in the 2 × 0.8 sky region around the Galactic Center. In this paper, we study the spatial and luminosity distributions of these sources according to their spectral properties. Fourteen bright sources detected are used to fit jointly an absorbed power-law model, from which the power-law photon index is determined to be ∼2.5. A...
متن کاملA DEEP Chandra CATALOG OF X-RAY POINT SOURCES TOWARD THE GALACTIC CENTER
We present a catalog of 2357 point sources detected during 590 ks of Chandra observations of the 17-by-17 arcminute field around Sgr A. This field encompasses a physical area of 40 by 40 pc at a distance of 8 kpc. The completeness limit of the sample at the Galactic center is 10 erg s (2.0–8.0 keV), while the detection limit is an order of magnitude lower. The 281 sources detected below 1.5 keV...
متن کاملRadial Distribution of X-ray Point Sources near the Galactic Center
We present the logN-logS and spatial distributions of X-ray point sources in seven Galactic Bulge (GB) fields within 4 from the Galactic Center (GC). We compare the properties of 1159 X-ray point sources discovered in our deep (100 ks) Chandra observations of three low extinction Window fields near the GC with the X-ray sources in the other GB fields centered around Sgr B2, Sgr C, the Arches Cl...
