Covers gravitational lensing in astrophysics, including deflection angle, Einstein radius, lens solution, and its application to galaxies and the universe.
Explores gravitational motion equations, energy conservation, angular velocity, orbits, relativity effects, black holes, time dilation, cosmology, and rotational equilibrium.
Explores the classification and statistics of AGN, black holes, unified AGN model, variability, megamasers, orbital motion measurement, and time-delay cosmography.
