Skimmed paper on emission from narrow-line Seyfert 1 galaxy 1H 0707-495 right down at the event horizon.

Looked at some new figures from Chajet, and discussed results.

Redshifted-trough BAL quasars: looked at images for signs of binarity; made lots of spiffy figures; revised most sections of the text (but two figures and two sections remain).

Resolved an issue regarding average inclinations of randomly inclined disks: the median inclination angle (i=0 being face-on) is 60 degrees, but the mean is 57.3 degrees; and are thus in agreement.

  1. Median vs mean inclination angle: For your teaching blog, that's a great problem-set problem. I guess the mean and the median of cos(i) are identical at 0.5? In general I think we should deal in cos(i) not i, right?
