Accretion Geometry of Ultra-Luminous X-ray Source Population Study
Abstract
Eddington luminosities can be used to determine the maximum theoretical luminosity of an accreting system. Ultra-Luminous X-ray sources (ULX’s) are a class of high energy X-Ray emitters that seem to break with typical Eddington limited accretion luminosities. However, when using them to describe intermediate mass black holes (IMBH), ULXs obtain a luminosity greater than what the stellar mass black holes could achieve. Luminosities this high cannot be explained by normal accretion physics, therefore, another aspect of the IMBH must be considered. In this presentation, multiple ULX luminosities are analyzed and compared directly to multiple black hole accretion geometries. From this analysis, we hope to find a model that best fits the luminosity of these IMBHs. This, in turn, will allow us to better understand the accretion physics that is occurring within these unique systems.
