15. Supermassive Black Holes
Μεταφορτώθηκε στις 29 Σεπ 2008
Frontiers/Controversies in Astrophysics (ASTR 160)
The
lecture begins with a question-and-answer session about black holes.
Topics include the extent to which we are sure black holes exist in the
center of all galaxies, how massive they are, and how we can observe
them. The lecture then turns to strong-field relativity: relativistic
effects that are unrelated to Newtonian theory. The possibility of
testing predictions of the existence of black holes is discussed in the
context of strong-field relativity. One way we might learn about black
holes is through observation of the orbit of the companion star in an
X-ray binary star system. Through this we can estimate the mass of the
compact object. The lecture ends with an explanation of how astronomers
find black holes, and how Professor Bailyn was able to discover one
himself.
