Research Technician IV (Multiple Positions)
Posting Number: req9986
Department: Steward Observatory
Location: Main Campus
Address: Tucson, AZ USA
Research interns will work on simulated data for the James Webb Space Telescope (JWST) to improve the code and optimize it for exoplanets. Interns will improve the stages of the JWST pipeline to best correct for detector noise and systematics. Interns will also improve code to fit light curves to turn the data products into physical parameters.
The University of Arizona has been recognized for our innovative work-life programs. For more information about working at the University of Arizona and relocations services, please click here.
Duties & Responsibilities
- Improve Stage 1 to best reduce the impacts of detector noise.
- Improve Stage 3 of the pipeline to optimize the aperture sizes and centroiding in the presence of telescope jitter.
- Work on generalized code that makes it easy to run the pipeline on many objects
Improving documentation, testing and debugging software tools.
These include :
- the official jwst pipeline usage
- modifications to the jwst pipeline
- how to use the "tshirt" pipeline
- how to use the "jtow" wrapper for the jwst pipeline
- how to use the "splintegrate" tool to split up integrations
Training new students in the science, software tools, detector conventions to prepare for future research. Experienced interns will be responsible for teaching new interns how to us Python, the basics of exoplanet science and how to conduct research and organize themselves.
Fitting lightcurves of the data to obtain physical parameters of the simulated planets. Interns will use the publicly available "exoplanet" tool to fit lightcurves with Bayesian inference. This will include setting up the input data, setting priors for the model, fitting multiple lightcurves simultaneously and synthesizing the results. "exoplanet" will require installing and debugging the pymc3 Bayesian inference tool.
Reading scientific literature to understand the context of exoplanet atmospheres, attending seminars and workshops. Interns will need to read papers and documents about JWST, exoplanet science, time
series, Bayesian inference and detectors. Science talks and seminars will be available to learn about new science results and JWST tools.
