Astronomy 162, Stars, Galaxies, and the Universe, is part 2 of a
2-quarter introductory Astronomy for non-science majors taught at The
Ohio State University. This podcast presents lecture audio from
Professor Richard Pogge's Winter Quarter 2006 class. All of the
lectures were recorded live in 1008 Evans Laboratory on the OSU Main

What are Active Galaxies and Quasars? We have good reason to
think that buried deep in the hearts of nearly every (?) bright galaxy is
a supermassive black hole with masses of millions or even billions of
times the mass of the Sun. Most, like the one in our Milky Way,
are quiescent, but in about 1% of galaxies, they are fed enough matter
(up to about a sun's worth per year), and light up as an Active Galactic
Nucleus (AGN) that can outshine an entire galaxy full of billions of stars.
This lecture reviews the observed properties of Active Galaxies, the
riddle of the Quasars, and the recognition that they are powered by
the accretion of matter onto supermassive black holes. The lecture ends
with some open questions in this active area of current research.
Recorded 2006 February 16 in 1008 Evans Laboratory on the Columbus campus
of The Ohio State University.
