Abstract:
In my talk, I will first review the progress on black-hole accretion disk models in the past 45 years. By taking the thermal equilibrium into consideration, I will discuss the physical reason for outflows in accretion systems. Consequently, I will introduce our recent works on the applications of accretion models to ultra-luminous X-ray sources and gamma-ray bursts. In addition, I will mention our recent progress on searching for stellar-mass black hole candidates by the LAMOST spectra.
