2010 August 2
(Deadline blown, quasi-intentionally; some work on the Cyg X-3 lightcurve project has become higher-priority as we’ve realized that the summer is coming to an end …)
What have I been doing for the past four years, anyway? The usual approach to this portion of the qual seems to ignore classes, teaching, and outreach, so we’ll skip those.
In my first few years, I did some observing for Geoff Marcy’s group, which led to coauthorships on a few papers:
- Winn+: HAT-P-1b lightcurve: 2007, 2007 erratum
- Johnson+: HAT-P-1b Rossiter-McLaughlin: 2008
- Johnson+: two Jovian exoplanets: 2008
- Peek+: two Jovian exoplanets: 2009
I gained some great optical observing experience from this involvement but don’t think it’s worth treating in any depth.
ATA Broadband Spectra🔗
My first major ATA project culminated in Williams & Bower 2010, a study of the broadband spectra of three starforming galaxies in an attempt to understand the physical underpinnings of the FIR/radio correlation of starforming galaxy emission. Here’s a bibliography of some relevant theoretical and observational work:
- Thompson+ 2006 pretty directly inspired the project
- Völk 1989 proposed the “calorimeter theory” that we investigate
- Blandford & Eichler 1987 is a classic reference on cosmic ray acceleration in shocks
- Lisenfeld+ 1996 is one somewhat recent example of theoretical work on the FIR/radio correlation
- Price & Duric 1992 is another
- Thompson+ 2009 updates Thompson+ 2006 with some ideas based on SNRs
- More recent work: Lacki+ 2010, Lacki & Thompson 2010 are further work from the same group.
- Sargent+ 2010 is one of many papers looking at the evolution of the FRC with redshift.
In the course of working on the broadband spectra project, I also spent a lot of time developing various pieces of the ATA infrastructure and data analysis chain, mostly in the form of software:
- Time spent modernizing the MIRIAD build system, fixing bugs, maintaining its port to Mac OS X (and I don’t even use a Mac! That’s how nice of a guy I am.)
- miriad-python, a Python binding for MIRIAD that I use all the time
- ATA data analysis tools built on miriad-python: calctsys, dualscal, qimage, many and varied one-off tools
- My UV data visualizer/editor
- “hex” scripts for weekly ATA calibration observations
- A system for running commensal observations with the beamformer and correlators on the ATA
- A few other smaller things of somewhat less interest: the broadband spectra observing scripts, quasi-defunct atacursesstatus program, a Python plotting library, work on pympfit, Python bindings to NOVAS/SOFA/etc, …
