 Galaxy properties A X-ray All-Sky Survey: Extragalactic and Galactic Source Populations

Abstract

All-sky surveys at high energies have revolutionized our view of Active Galactic Nuclei (AGNs) and galactic sources. While the successful ongoing surveys by NASA’s Swift mission and by ESA’s INTEGRAL mission count hundreds of such sources, essential issues related to their properties and cosmological evolution call for more sensitive surveys rather than larger number of objects. To address these issues we have developed a new survey technique by merging the independent observations of Swift and INTEGRAL: the Swift-INTEGRAL X-ray (SIX) survey.
This talk will review the new observing technique and how it boosts the sensitivity. Especially the INTEGRAL mission has performed dedicated deep observations to allow this technique reaching unmatched survey sensitivity.
The results will be discussed in the context of cosmological evolution of AGNs and blazars. Also results from the galactic source populations will be discussed. I will show how the results tie in well with deep surveys performed by NuSTAR, which is the first focusing telescope at high energies.
