One thing I wanted to try on my sabbatical was writing a very short paper over a weekend. Didn't quite make it (and it was even a long weekend!), but I mostly ruled out "polar" BAL quasars; remaining tasks are:
DONE: 1) Check my math, both formulas and numbers.
DONE: 2) Dig up the FIRST and NVSS peak flux densities AND THEIR UNCERTAINTIES for both epochs for all the objects in Table 1.
DONE: 3) Take the formulas for rmax (Eqs 4 & 5) and beta_perp^min (Eq 9), come up with formulas for their uncertainties.
DONE: 4) Compute uncertainties on rmax, T_b,q and beta_perp^min using the errors on fluxes found above.
DONE: 5) Discuss more references, write conclusions.
I'll let it sit a week for Laura and I to look it over again, then submit!

Present
Am focusing on disk wind line profile paper, so previous post may be updated more often than new posts made.
Last week and a half has been some disk wind thinking, a bit of X-ray thinking, a Gemini referee report, Skype with Rogerson and with Chajet, but mostly a whole heck of a lot of postings about papers from the literature on Shareflow. There's a whole bunch of annotated hardcopy papers I won't be taking back across the pond with me....

Future
Time to start pushing my long-delayed paper on accretion disk (AD) winds out the door.
To Do List (more or less priority ordered)
* MOSTLY DONE (re)read related papers & post on ShareFlow
* MOSTLY DONE reread paper, freshen up text, verify paper structure ok, ID any new "to do" items
when I was last working on the paper intensively, I left several questions hanging; need to decide which to address and which to leave for the future:
* Finally understood; program adjustment DONE: is Q only important in the 0.3 < tau < 3 regime?
* expressions for Mdot = 4 pi rho(r) r^2 v_r(r) C_f(r) = const for r>r_launch,max
* DONE Matlab implementation of conical emitting region equations
* DONE add erfc() to tau, and Q-dependence in denominator of x^2
* share Matlab diagnostic programs
* log-linear Q
* Knigge et al. Q
* what parameter space to study in first paper
* which lines: CIV, MgII, demo CIII? Ha,Hb? (but comparison with RM not possible yet)
* which parameters to vary, and over what ranges?
* for them, do final line profile runs for varying wind launch angle and inclination
* Fine et al. style analysis of sigma(FWHM) distribution (CIV and MgII)
* blueshifts
* EWs
* convert latex to MNRAS style
* write up results of Fine et al. style analysis
* update references

Past
Finished and gave talk on PHL 1811 analogs to IoA X-ray group on Friday, after considerable background reading. Good point from Andy Fabian led me to investigate reflection-dominated X-ray spectra and think about models of AD spectra; will post to Shareflow soon.
