Search for Ultra-luminous X-ray Sources in Nearby GalaxiesAbstract. Little is presently known about the nature of ultraluminous X-ray sources (ULX). Different hypotheses have been proposed to explain their properties: intermediate-mass black holes, Kerr black holes, young supernova remnants (SNR), or background active galactic nuclei (AGN). Some of the current problems and open questions in this research field are here reviewed. |
