Correction terms to Newton law due to induced gravity in AdS background

We calculate small correction terms to gravitational potential on RandallSundrum brane with an induced Einstein term. The behaviors of the correction terms depend on the magnitudes of AdS radius k−1 and a characteristic length scale λ of model. We present the gravitational potential for arbitrary k and λ at all distances. ∗E-mail address: [email protected] 1 Braneworld is based on t...

X-ray background measurements with XMM-Newton EPIC

We discuss the methods used to compile a high signal-to-noise dataset representative of both the instrumental and cosmic background signal measured at high galactic latitude by the XMM-Newton EPIC cameras. The characteristics of the EPIC background are described and the potential applications of the derived dataset in general science analysis are outlined. In the case of the cosmic X-ray backgr...

Studying the Cosmic X-ray Background with Xmm-newton

We present a work in progress aimed at measuring the spectrum of the Cosmic X-ray Background (CXB) with the EPIC detectors onboard XMM-Newton. Our study includes a detailed characterization of the EPIC non X-ray background, which is crucial in making a robust measurement of the spectrum of CXB. We present preliminary results, based on the analysis of a set of Commissioning and Performance Verif...

Properties of the background of EPIC - pn onboard XMM - Newton

We have investigated the background properties of EPIC-pn onboard XMM-Newton to establish the background subtraction method. Count rates of the background vary violently by two orders of magnitude at the maximum, while during the most quiet period, these are stable within 8 % at a 1 σ level. The overall spectrum is dominated by particle events above 5 keV, and its spatial variation is also foun...

Xmm - Newton Observations of the Diffuse X - ray Background

We analyzed two XMM-Newton observations in the direction of the high density, high latitude, neutral hydrogen cloud MBM20 and of a nearby low density region that we called the Eridanus hole. The cloud MBM20 is at a distance evaluated between 100 and 200 pc from the Sun and its density is sufficiently high to shield about 75% of the foreground emission in the 3/4 keV energy band. The combination...
