This book discusses many of the recent theoretical and observational developments that have significant implications for astronomy and astrophysics. The main themes are (i) cosmology, (ii) gravitational wave astronomy and gravitational physics, (iii) stellar astrophysics, and (iv) active galactic nuclei and disk accretion. There are also contributions on the solar system.
