1. Original: X-ray Spectral Analysis of a Serendipitously Observed Active Galactic Nucleus
University essay from KTH/Skolan för teknikvetenskap (SCI)Abstract : An active galactic nucleus (AGN) is a region in the center of a galaxy with a supermassive black hole continuosly accreting material. This accretion gives rise to large amounts of radiation across the whole electromagnetic spectrum, and largely affects the regions around the AGN and the evolution of the whole galaxy. READ MORE

2. Ultraluminous sources in X-ray sky surveys
University essay from Uppsala universitet/HögenergifysikAbstract : Ultraluminous X-ray sources (ULXs) are extragalactic, non-nuclear, point-like X-ray sources whose luminosity supersedes that of the Eddington limit of an accreting stellar mass black hole (L> 10 ^ 39 erg / s). Most of them are powered by black holes and neutron stars undergoing genuine super-Eddington accretion, with a small handful of candidates being consistent with sub-Eddington accretion on an intermediate mass black hole.

3. Investigating super-Eddington accretion flows in Ultraluminous X-ray sources
University essay from Luleå tekniska universitet/RymdteknikAbstract : It is now widely known that most of the large galaxies we observe (e.g. the Milky Way) host in their center a supermassive black hole ($10^{6}-10^{9}$ $M_\odot$). READ MORE

5. X-ray Spectroscopy of Distant Active Galactic Nuclei
University essay from KTH/Skolan för teknikvetenskap (SCI)Abstract : The physical structure and behaviour of stars have been studied extensively throughout centuries.In contrast, the existence of objects now known as Active Galaxies has only been established since a couple of decades. READ MORE
