Title X-Ray variability studies of NGC4051
Alternative Title Μελέτη μεταβολής ακτίνων Χ στον ενεργό γαλαξία NGC 4051

Abstract NGC 4051 is one of the brightest and most variable X-ray sources. It has been observed by most major satellites in the last forty years. The purpose of this study is to use data from ESA’s XMM-Newton satellite in order to construct lightcurves and analyse the power spectrum of NGC 4051 in various energy bands. We estimated the power spectrum for five different energy bands and found that its parameters are energy dependent. This is the first time the energy dependence of the properties of NGC 4051’s power spectrum has been reported.
