Here, one of the world's leading astrophysicists provides the
first comprehensive and logically structured overview of the many
ideas and discoveries pertaining to the supermassive black hole at
the galactic center known as Sagittarius A*. By far the closest
galactic nucleus in the universe, Sagittarius A* alone can provide
us with a realistic expectation of learning about the physics of
strong gravitational fields, and the impact of such fields on the
behavior of matter and radiation under severe physical conditions.
Its proximity may even provide the opportunity to directly test one
of general relativity's most enigmatic predictions--the existence
of closed pockets of space-time hidden behind an event horizon. The
plethora of research on Sagittarius A* since its discovery in 1974
has long seemed an interwoven pattern of loose threads. No one has
successfully synthesized this growing body of work into a
manageable, coherent book both for professional researchers and for
students taking courses focusing on black holes and galactic
nuclei--until now. With Fulvio Melia's The Galactic
Supermassive Black Hole , readers finally have at their
disposal a one-volume crucible of essential ideas, logically
streamlined but with thorough references for those wishing to
explore the various topics in greater depth.
