Postdoctoral researcher in neutron star astrophysics


Publication date 9 January 2020


Closing date 28 February 2020


Level of education PhD


Hours 38 hours per week


Salary indication €2,709 to €4,274 gross per month


Vacancy number 20-007


Are you interested in understanding the nature of the densest nuclear matter in the Universe? Or in using relativity to map the surfaces of neutron stars? We welcome applications for a 3-year postdoctoral position to work on neutron star astrophysics with Prof. Anna Watts and her group at the Anton Pannekoek Institute for Astronomy (API) at the University of Amsterdam (UvA). The successful applicant will join the ERC Consolidator Grant funded project AEONS (Advancing the Equation of state Of Neutron Stars).


NASA’s NICER X-ray telescope has recently delivered its first measurements of neutron star mass and radius – key probes of the dense matter Equation of State (EOS) – using the new technique of Pulse Profile Modeling (PPM). PPM combines astrophysical modeling, relativistic ray-tracing, and Bayesian inference using high performance computers to deliver not only mass and radius but also a map of the hot emitting regions on the stellar surface. Our group played a major role in this effort, and the AEONS team will continue this work, analyzing new NICER data and carrying out simulations to address the complexities that we have encountered. AEONS also looks ahead to the next generation of large-area X-ray timing telescopes. Missions such as eXTP and STROBE-X are targeting accreting neutron stars for PPM – but these pose challenges such as variability, surface pattern uncertainty, and the need to consider X-ray polarimetry data. AEONS will tackle these issues, and study how to embed PPM in a multi-messenger EOS inference framework with radio and gravitational wave constraints. If you have a background in electromagnetic / gravitational wave neutron star astrophysics, dense matter physics, astrostatistics or computational astrophysics we encourage you to apply.


What are you going to do?

You will join the vibrant high energy astrophysics group at API, and can expect to collaborate with our colleagues in the Gravitation and Astroparticle Physics (GRAPPA) Institute. Two postdoctoral researchers will eventually be hired within the AEONS team, with broad goals of quantifying the robustness of PPM and embedding PPM in the wider multi-messenger and nuclear physics context. There is flexibility in how this works in practice, and applicants with interests in either or both areas are welcome. You will work closely with the PhD students on the team, and will have the opportunity to supervise Bachelor and Masters student research projects. You will also be encouraged to pursue your own research lines (please highlight any synergies of existing projects with AEONS in your application).

What do we require?

Applicants should have (or expect to obtain before the start date) a PhD in astrophysics, and have a track record that is relevant to the goals of the AEONS project.


Our offer

A temporary contract for 38 hours per week, preferably starting September 2020 (negotiable) , for the duration of 36 months.


The salary, depending on relevant experience before the beginning of the employment contract, will be €2,709 to €4,274 (scale 10) gross per month, based on full-time (38 hours a week), exclusive 8% holiday allowance and 8.3% end-of-year bonus. A favorable tax agreement, the ‘30% ruling’, may apply to non-Dutch applicants.  The Collective Labour Agreement of Dutch Universities is applicable.
