Sentences with phrase «kev band»

There are two substantial X-ray dips (very strong in the 15 - 50 keV band, weaker at lower energies) that are separated by an interval equal to the X-ray period.

The same periodicity is present in both the 2 - 20 keV and 15 - 50 keV bands, but with a 0.1 phase offset 40d).

We characterized the evolution in the hard X-ray band and showed that for the joint ISGRI - XRT fits, the e-folding energy decreased from 350 keV to 130 keV, while the energy where the exponential cut - off starts increased from 75 keV to 112 keV as the decay progressed.We investigated the claim that high energy cut - offs disappear with the compact jet turning on during outburst decays, and showed that spectra taken with HEXTE on RXTE provide insufficient quality to characterize cut - offs during the decay for typical hard X-ray fluxes.
