Post-doctoral Positions and Fellowships

Large Academic
Leiden University
Department Name: 
Leiden Observatory
Job Announcement Text: 

Using the 38 LOFAR stations in the Netherlands, the LOFAR Surveys Key Science Project is currently conducting a series of low-frequency radio surveys with a range of depth, area and frequency to address fundamental questions in many major astrophysical areas, ranging from exoplanets, galaxy clusters, AGN, the epoch of reionisation and cosmology. The next step is to also use the 15 international stations spread over 8 countries in Europe to carry out (sub)arcsec imaging of large areas of the sky at low frequencies. While we have shown that this is possible, this will be complicated and computer-intense. We, therefore, are soliciting applications from black belt radio astronomers or academic software developers who would help to update the existing pipelines to enable high angular resolution large scale surveying. Experience with low-frequency interferometric observations, calibration and imaging algorithms and python coding is a pre.

The successful applicant(s) will be working at Leiden Observatory which is 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.

Candidates must have a PhD in astronomy, physics or computer sciences. The position is for 3-5 years with a target starting date early 2021. However, the start date is flexible. Applications should be submitted electronically at A complete application includes a cover letter, CV, publication list, and a two-page statement of research experience and interests. In addition, applicants should arrange for three reference letters to be uploaded to the same address before the indicated deadline. Questions may be directed to Dr R. J. van Weeren ( or Prof H. J. A. Röttgering (
