In all these systems it is widely accepted that the X-ray emission is produced by Compton up-scattering of lower energy seed photons in a hot corona or accretion flow, and here these processes are examined through a study of the X-ray spectral variability of each source. A new technique is introduced, in which models are fitted to over 2 million X-ray spectra on time-scales as short as 16 ms, and subsequently it is shown that the nature of the correlation between intensity and spectral index is strongly dependent upon the spectral state of the black hole. Finally, the results of an extensive survey of nearby galactic nuclei using the Chandra X-ray telescope are presented in the form of images and spectra, and these results are used along with data from the literature to search for Compton-thick nuclei. 410 0$aSpringer Theses, Recognizing Outstanding Ph.D. Research,$x2190-5053 606 $aAstronomy$vObservations 606 $aAstronomy?Observations 606 $aAstronomy, Observations and Techniques$3https://scigraph.springernature.com/ontologies/product-market-codes/P22014 615 0$aAstronomy 615 0$aAstronomy?Observations. 615 14$aAstronomy, Observations and Techniques. 676 $a522.6863 700 $aSkipper$b Chris$4aut$4http://id.loc.gov/vocabulary/relators/aut$0792288 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910300427803321 996 $aFast Spectral Variability in the X-ray Emission of Accreting Black Holes$91771572 997 $aUNINA
