Until Swift's hard X-ray survey, astronomers never could be sure they had counted the majority of the AGN.
9] electron volts), the radiation is highly polarized, sharply concentrated in the direction of particle travel and the spectrum has a very wide, smooth energy distribution with extremely high intensity in the vacuum ultraviolet, soft- and hard X-ray regions.
They can already generate laser-like X-ray beams in the soft X-ray region and believe they have discovered how to extend the process all the way into the hard X-ray region of the electromagnetic spectrum.
Along with the XRS are four X-ray Imaging Spectrometer (XIS) instruments, a collaboration among Japanese institutions and the Massachusetts Institute of Technology; and the Hard X-Ray Detector (HXD), built by the University of Tokyo, ISAS and other Japanese institutions.
Some of its important results include the first imaging of a flare in gamma-rays, the discovery of strong polarization in a cosmic gamma-ray burst; the first detection of continuous glow from the sun at 3-15 KeV energies; and the first hard X-ray imaging spectroscopy of flares from thermal to non-thermal energies.
