Lecture 3:  Models for the variable multi-wavelength emission of black hole
binaries: accretion flow
- The structure of inner accretion flow inferred from X-ray spectral modelling
- The most popular model for the X-ray fast variability and QPOs
- Fast optical variability from the accretion flow:
   * disk reprocessing
   * synchrotron emission from non-thermal particles in the hot corona
- Optical QPOs  from the accretion flow
