We present the calibration of the Nuclear Spectroscopic Telescope Array (NuSTAR) X-ray
satellite. We used the Crab as the primary effective area calibrator and constructed a piece …

Based on a spectral analysis of the X-ray continuum that employs a fully relativistic accretion
disk model, we conclude that the compact primary of the binary X-ray source GRS 1915+ …

The well-known Crab Nebula is at the center of the SN1054 supernova remnant. It consists
of a rotationally powered pulsar interacting with a surrounding nebula through a relativistic …

We have developed a framework for the Monte Carlo simulations of X-Ray Telescope (XRT)
and X-ray Imaging Spectrometer (XIS) on board Suzaku, mainly for the scientific analysis of …

The continuum high-energy gamma-ray emission between 1 GeV and 10 5 GeV from the
Crab Nebula has been measured for the first time in overlapping energy bands by the Fermi …

ABSTRACT We use Swift BAT Earth occultation data at different geomagnetic latitudes to
derive a sensitive measurement of the cosmic X-ray background (CXB) and of the Earth …

The Hitomi (ASTRO-H) mission is the sixth Japanese x-ray astronomy satellite developed by
a large international collaboration, including Japan, USA, Canada, and Europe. The mission …

Aims. We study the spectrum of the cosmic X-ray background (CXB) in energy range~ 5-100
keV. Methods. Early in 2006 the INTEGRAL observatory performed a series of four 30 ks …

Thermal emission during X-ray bursts is a powerful tool for determining neutron star (NS)
masses and radii if the Eddington flux and the apparent radius in the cooling tail can be …

XL-Calibur is a hard X-ray (15-80 keV) polarimetry mission operating from a stabilised
balloon-borne platform in the stratosphere. It builds on heritage from the X-Calibur mission …
