Wide-band X-ray variability of GRS 1915+105 observed with BeppoSAX
The Galactic Microquasar GRS 1915+105 was observed by the Narrow Field Instruments onboard BeppoSAX in two pointings during year 2000. We present the preliminary results of wideband study of the observed variability, carried out also with the wavelet analysis.
متن کاملBroad band X–ray spectra of M31 sources with BeppoSAX
We present the first spectral study of the X–ray emitting stellar sources in M31 in the energy band from ∼ 0.1 to 10 keV. We find that the globular cluster sources have spectral characteristics consistent with those of the Milky Way object, namely that the spectrum can be described by a thermal model with ∼ 6–20 keV from ∼ 2 to 10 keV. Evidence of high absorption in some of these sources is mos...
متن کاملAsymmetrical-fed RHCP Wide-Band Slot Element for X-Band applications
An outstanding square slot element, for x-band wireless applications with asymmetric coplanar waveguide fed (CPW) is proposed. Various shapes of metallic strips are utilized as grounded stubs for providing Right Hand Circular Polarization (RHCP) functionality and wide-band properties. By adjusting the proposed stubs and hook-shaped radiator, length and positions, wider impedance band width is o...
متن کاملBroad - band BeppoSAX observation of the low - mass X - ray binary X 1822 - 371
Results of a 1997 September 9–10 BeppoSAX observation of the 5.57 hr low-mass X-ray binary (LMXRB) X 1822371 are presented. The 0.3–40 keV spectrum is unusually complex and cannot be fit by any of the standard models applied to other LMXRB. At least two components are required. One component has a shape consistent with that expected from the Comptonization of an input soft (Wien) spectrum while...
متن کاملDetecting gamma-ray bursts from M31 with the wide field X-ray cameras on board BeppoSAX
Gamma-ray bursters emit a small fraction of their flux in X rays, and because X-ray detectors are often very sensitive they may probe the gamma-ray burst universe more deeply than the current best gamma-ray instruments. On the reasonable assumptions that spectra of bursts observed by BATSE may be used to predict the X-ray fluxes of gamma-ray bursts, and that any corona of bursts around M31 is s...
