Deep Sky Objects and the X - ray Background
نویسنده
چکیده
Deep observations of the X-ray Sky have now resolved most of the X-ray Background. Obscured active galaxies are a key component. The obscured objects which dominate at fluxes above 10 −15 erg cm −2 s −1 are discussed and models in which the growth of wind-blowing active nuclei determine both black hole and galaxy mass are presented. The power from accretion is large and can easily influence the gas in a host galaxy, as well as heat the intergalactic medium.

The X-ray Background and the Deep X-ray Surveys
The deep X-ray surveys performed by the two major X-ray observatories on flight, Chandra and XMM, are being resolving the bulk of the cosmic X-ray background (XRB) in the 2–10 keV energy band, where the sky flux is dominated by extragalactic emission. Although the actual fraction depends on the absolute sky flux, which is measured with an uncertainty of ∼ 40%, most of the XRB is already resolve...
متن کاملForty Years of X-Ray Binaries
In 2012 it was forty years ago that the discovery of the first X-ray binary Centaurus X-3 became known. That same year it was discovered that apart from the High-Mass X-ray Binaries (HMXBs) there are also Low-Mass X-ray Binaries (LMXBs), and that Cygnus X-1 is most probably a black hole. By 1975 also the new class of Be/X-ray binaries was discovered. After this it took 28 years before ESAs INTE...
متن کاملWide field x-ray telescope a moderate class mission
Sensitive surveys of the X-ray universe have been limited to small areas of the sky due to the intrinsically small field of view of Wolter-I X-ray optics, whose angular resolution degrades with the square of the off axis angle. High angular resolution is needed to achieve a low background per source, minimize source confusion, and distinguish point from extended objects. WFXT consists of three ...
متن کاملReconstructing light curves from HXMT imaging observations
The Hard X-ray Modulation Telescope (HXMT) is a Chinese space telescope mission. It is scheduled for launch in 2015. The telescope will perform an all-sky survey in hard X-ray band (1 250 keV), a series of deep imaging observations of small sky regions as well as pointed observations. In this work we present a conceptual method to reconstruct light curves from HXMT imaging observation directly,...
متن کاملبررسی خوردگی اشیا آهنی کشف شده از حفاری بوکان
During the excavations of Tappeh Ghalaychi near the city of Bukan in west Azerbaijan province, a number of iron and bronze objects were found that are belonged to the 8th century B.C. The corrosion of iron objects were studied after chemical analysis. As these objects have a very high cultural value, chemical analysis by using destructive methods is not possible, therefore scanning electr...
