Earth X-ray albedo for cosmic X-ray background radiation in the 1–1000 keV band
نویسندگان
چکیده
We present calculations of the reflection of the cosmic X-ray background (CXB) by the Earth’s atmosphere in the 1–1000 keV energy range. The calculations include Compton scattering and X-ray fluorescent emission and are based on a realistic chemical composition of the atmosphere. Such calculations are relevant for CXB studies using the Earth as an obscuring screen (as was recently done by INTEGRAL). The Earth’s reflectivity is further compared with that of the Sun and the Moon – the two other objects in the Solar system subtending a large solid angle on the sky, as needed for CXB studies.

Earth X-ray albedo for CXB radiation in the 1-1000 keV band
We present calculations of the Cosmic X-ray background (CXB) reflection by the Earth atmosphere in the 1-1000 keV range and compare it with the reflection by the Moon and the Sun. The calculations use realistic chemical composition of the Earth atmosphere and include all relevant physical processes. An analytic approximation to the Earth X-ray albedo is provided, which should be accurate down t...

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 albedo emission in the 15–200 keV band. We compare our CXB spectrum with recent (INTEGRAL, BeppoSAX) and past results (HEAO-1) and find good agreement. Using an independent measurement of the CXB spectrum we are able to confirm our re...

Cherenkov radiation is generated when relativistic charged particles move in a medium with refractive index larger than unity. Although, the refractive index is generally smaller than unity in X-ray region, in the vicinity of atomic absorption edges, the refractive index may exceed unity and Cherenkov radiation can be generated in soft X-ray region with a narrow band width. In this paper, the s...
متن کاملThe spectrum of the cosmic X - ray background observed by RTXE /
We have analyzed a large set of RXTE/PCA scanning and slewing observations performed between April 1996 and March 1999. We obtained the 3-20 keV spectrum of the cosmic X-ray background (CXB) by subtracting Earth-occulted observations from observations of the X-ray sky at high galactic latitude and far away from sources. The sky coverage is approximately ∼ 22.6 · 10 3 deg 2. The PCA spectrum of ...
