Super-Eddington Luminosities from Super-Eddington Accretion: Powering Ultra-Luminous X-ray Sources with Stellar Mass Black Holes
Aristotle Socrates (Princeton ) - 1 May at 12:00 noon
Ultra-Luminous X-ray Sources (ULXs) have recently gained much attention.
Due to their large inferred bolometric X-ray luminosities, these
extragalactic sources are thought to be powered by accretion onto a
new class of blacks i.e., Intermediate Mass Black Holes. Exciting as
this possibility may be, we show that ULX behavior can be explained
by super-Eddington accretion onto the well-established stellar mass
black holes. By using well-tested theoretical arguments, we show
that ULX behavior readily fits into the pre-existing phenomenological
paradigm of black hole X-ray binary accretion.
The seminar will be held in 544 Campbell Hall.
