High-resolution view of high mass accretion to understand black holes growth
Abstract
The growth of early supermassive black holes requires high accretionrate releasing huge amount of radiation and winds slowing downboth accretion rates and start formation. This programme focuses onthe physics of high-mass accretion on the stellar mass level wheresuper-Eddington luminosities are more commonly observed. We propose deepX-ray observations of the corner stone supersoft Ultra-Luminous X-raysource (ULX) NGC 247 X-1 to probe the very soft end of the hardnessdistribution necessary to complete the current view. This is theonly source that continuously switches between supersoft and classicalultraluminous states, providing a unique workbench for our study. With a1 Ms XMM-Newton program, we will detect ultrafast outflows and understandhow super-Eddington accretion works.
