ASTR 5460, Fri. May 2, 2003

Evaluations (official and unofficial)

Reminders/Assignments

Finish Quasars and Active Galactic Nuclei

Reminders/Assignments

Research Homework Update

Dan finished phase 1, conducting phase 2

Chris, Sey, and Cassandra primary now

Jon and Sabrina should see me soon

Presentation topics

Galex launched!

Presentation Topics

Plan for 20 minutes, plus questions.

Other astronomy faculty are invited.

Topics:

Gunn-Peterson Test and Reionization

Supernovae and the Accelerating Universe

Weighing Supermassive Black Holes

The Hubble Deep Fields

Sub-millimeter (SCUBA) Galaxies

X-ray Background

Quasars and Active Galactic Nuclei (AGNs)

The AGN “Zoo”

Orientation and Unified Models

“Unified Models” explain some of the different classes of AGN, particularly type 1 and type 2 Seyferts, via orientation.

For specifics, see the Annual Reviews article by Antonucci, 1993, a “bishop” in the “Church of Unification.”

Quasar Spectral Energy Distributions (SEDs)

Very nice and relatively brief review article from “Quasars and Cosmology” conference by Belinda Wilkes (CfA), a world expert on the subject:

http://nedwww.ipac.caltech.edu/level5/Sept01/Wilkes/Wilkes_contents.html

Must account for physical processes producing prodigious luminosity from radio wavelengths through the X-ray and even gamma ray regimes.

Particular features of interest include radio-jets and the radio-quiet vs. radio-loud dichotomy, the “big blue bump” that produces the optical/UV energy peak and is thought to arise from an accretion disk, and the far infrared that represents re-radiation by hot dust.
