Blinking Cursor
Research-wise, this week was Rogerson research evaluation, and some discussion of the BAL photovariability project. DeRobertis pointed out in the evaluation that if an absorbing cloud at a fixed distance from a quasar expands and decreases in density, it can effectively photoevaporate in an ion of interest (n goes down, L and d are constant, so ionization parameter U=L/nd^2 goes up). I don't think anyone's considered that possibility for BAL variability before.

Equinoctial
Chajet research evaluation passed; we resolve to make some better figures.
Read over redshifted BAL troughs ESO proposal.
Read over drafts of Rogerson research evaluation.
A few revisions to redshifted BAL draft paper.
That plus teaching, the parents in town, and being a bit under the weather fills up the week.

Centenarian
Passed the 100-post mark without noticing. Guess I'm getting forgetful.
Mon.: Continued reading paper for journal club. Skimmed another paper for colleagues. Brief discussion with Chajet. Email responses to Filiz Ak. Incorporated textual revisions to redshifted BAL quasar draft. ngCFHT.
Teaching: lecture prep, wrote & sent TA email. Moodling.
Tue.: Inclination-angle revision and email. Journal club. ngCFHT. Teaching: Moodling, Bit of TA organization.

Timing!
Breaking things down more than usual this entry, for my own edification:
Bus ride to York: wrote paragraph on ideas for followup work on redshifted BAL quasars
8-9 am: updated solar system model @ York website, thought & wrote about spectropolarimetry of above
9-10 am: thought & wrote about redshifted BAL quasar variability &c.
10-11 am: wrapped up internal draft on redshifted BAL quasars. Whew!
11-12 am: lunch, errands, short summary of paper on CIV/MgII emission on shareflow
noon - 1:30 pm: website prep for teaching tomorrow, errands
1:30 - 2:30 pm: prepped digital cameras for checkout by students taking constellation photos
2:30 - 3:30 pm: finished website prep for teaching tomorrow, brief chat with Rogerson re: research this month.
Bus ride home (early to avoid the rush): reading a little of a consulting group's report on Canadian astronomy
Evening: project management style discussion & implementation of a few more teaching items.

Figuring
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; http://adsabs.harvard.edu/abs/2006AJ....132.2231C and http://adsabs.harvard.edu/abs/2009ApJ...697.2057L are thus in agreement.
