Research: The study of hot plasmas in the X-ray band improved significantly since the launch of the satellites XMMNewton and Chandra. Even more exciting times are ahead of us with XRISM (to be launched early 2022) and Athena (to be launched in 2031).

Correct analysis of the data does not only depend on the instrument performance and its calibration but also on the correct modelling of these plasmas. This modelling is based on databases containing thousands to millions of transitions (e.g. SPEX, AtomDB) but the accuracy of these databases is often the limiting factor for the correct interpretation of high-resolution X-ray spectra.SRON has a long track record in this field (the SPEX code was developed at SRON) and plans to continue this into the next decade.

Therefore, SRON seeks a scientist for a tenure track position who is able to lead our contributions in this field. In addition to this contribution to the modelling, the scientist will also participate in front line research in this field, preferably with an emphasis on extragalactic astrophysics but good candidates in other fields are also encouraged to apply.

Expertise 

• demonstrated capability to produce model spectra of hot plasmas using detailed atomic data and to perform calculations of these atomic data;
• demonstrated track record in the field of observational astrophysics using high-energy satellites and high-resolution X-ray spectral data, including successful observation proposals led as PI.

This is a fulltime tenure track position with an initial employment period of four years. Together with the candidate we will set up a SMART assessment procedure with clear criteria and milestones. Upon successfully passing the evaluation after three years the candidate will be offered a permanent position.

The salary will be in accordance with the salary scales of NWO-I and is highly depending on education and experience. NWO-I has good secondary employment conditions such as:

• An end of year bonus of 8,33% of the gross yearly salary
• 42 days of vacation leave a year on full-time basis
• A holiday allowance of 8% of the gross yearly salary
• An excellent pension scheme
• Options for (additional) personal development
• Excellent facilities for parental leave

The candidate will be employed at SRON Utrecht, which moves in 2021 to Leiden. 

The start date of this position can be determined in mutual agreement.

SRON Netherlands Institute for Space Research

SRON's mission is to bring about breakthroughs in international space research. Therefore the institute develops pioneering technology and advanced space instruments, and uses them to pursue fundamental astrophysical research, Earth science and exoplanetary research. As national expertise institute, SRON gives counsel to the Dutch government and coordinates national contributions to international space missions. SRON stimulates the implementation of space science in our society.

The Astrophysics Program of SRON concentrates on the evolution of galaxies, star formation over cosmic time, and black holes. An important ingredient is connecting this science with the space instruments SRON builds and collaborating with the worldwide user community.
