Postdoctoral position Gaia/DPAC software development

Applications are invited for a postdoctoral position at Leiden Observatory to work on crowded field (spectro-)photometric data processing for the Gaia mission. Specifically, the work will result in algorithms and code, to be integrated into the DPAC processing pipeline, for the combination of repeated observations of blended sources in order to disentangle the overlapping Blue and Red Photometer prism spectra. The work will be guided by insights gained from a limited set of full frame images of crowded fields obtained with Gaia's Skymapper CCDs through the Service Interface Function (SIF).

The successful candidate will work under supervision of Anthony Brown and join the Gaia Data Processing and Analysis Consortium (DPAC). The work will be embedded in Coordination Unit 5 (CU5, photometry) of DPAC, where frequent interaction is foreseen with the other DPAC coordination units and with the working group analysing the SIF images. In addition a fraction of the time will be spent on supporting the catalogue validation activities of the Gaia group at Groningen University.

Leiden Observatory is the oldest university astronomy department in the world and the largest astronomy department in the Netherlands. Leiden is a charming university town with an international flair, located near Amsterdam.

The successful candidate will have a PhD in astronomy, physics, computer science, or mathematics by the starting date. Applicants experienced in the reduction of crowded field photometric data and in software development, particularly in Java, have a clear advantage.

The appointment is for a period of three years and comes with full benefits and a competitive salary. The anticipated start date of the appointment is January 1 2019 or soon thereafter.

Applications should be submitted electronically at and should include a curriculum vitae, publication list, a brief statement of research experience and interests. The application should arrange for at least two letters of reference to be uploaded. Review of applications will start on November 15 2018.
