Description
X-ray reflection spectroscopy is a powerful tool to study the accretion geometry near black holes and spacetime properties. The spirit of this method is to study the reprocessed corona emission by the cold accretion disk that extends close to the black hole. Previous X-ray reflection models consider a disk density of 10^-15 cm^-3, which is only appropriate for very massive black holes (> 10^7 M_Sun). In this talk, I will present a systematic study of high-density reflection effects for black hole XRBs. The study also provides insights into their accretion geometry in the bright hard and intermediate states.
