PhD position in Gravitational Wave Astroparticle Physics (GRAPPA, University of Amsterdam)

Help us pioneer gravitational wave probes of dark matter. Do you want to work at the interface of general relativity cosmology and data analysis and help build the tools that will make dark matter discoverable with future gravitational wave interferometers JoinGRAPPA as a PhD candidate within the ERC Advanced Grant De Tenebris (PI: G. Bertone) and develop precision models of binary black holes in astrophysical and dark matter environments.

Join Us!

You will join the GRAPPA centre of excellence for Gravitation and Astroparticle Physics at the University of Amsterdam embedded in the Institute of Physics at Amsterdam Science Park. You will be part of an international team working on dark matter in stronggravity environments in close contact with collaborators in the LISA community and beyond. Your mission is to advance the theory and computation needed to identify dark matter signatures in gravitational wave data.

What you will do

• Carry out research on gravitational wave sources in dark matter or related astrophysical environments;
• Present your work in group meetings and conferences; write and coauthor publications;
• Contribute to education (exercise classes and BSc/MSc supervision) as customary at the Faculty of Science.

What we ask of you

We are looking for highly motivated candidates who will have completed an MSc in Physics Astronomy or a closely related field by the start date; have a solid grounding in General Relativity and/or gravitational wave astrophysics; have experience in scientific programming (for example in Python or C); communicate clearly in English; and enjoy working in a collaborative research environment. It is a plus not a requirement if you are already familiar with cosmological or Nbody simulations basic concepts in gravitational wave data analysis or dark matter phenomenology.

This is what we offer you

We offer a temporary contract for 38 hours per week for the duration of 4 years (the initial contract will be for a period of 18 months and after satisfactory evaluation it will be extended for a total duration of 4 years). The gross monthly salary based on 38 hours per week ranges between 3059 to 3881 (Scale P).This does not include 8% holiday allowance and 83% year-end allowance. The UFO profile PhD candidate is applicable. A favourable tax agreement the 30% ruling may apply to non-Dutch preferred starting date is to be discussed. This employment should lead to a dissertation (PhD thesis). We will draft an educational plan that includes attendance of courses and (international) meetings. We also expect you to assist in teaching undergraduates and master students. You will have access to GRAPPAs vibrant research environment travel support and training (graduate courses schools and conferences).

You will work in this team

The Faculty of Science has a student body of around 8000 as well as 1800 members of staff working in education research or support services. Researchers and students at the Faculty of Science are fascinated by every aspect of how the world works be it elementary particles the birth of the universe or the functioning of the brain.

TheInstitute of Physics (IoP)of the University of Amsterdam is located in the centre of the Amsterdam Science Park. The IoP as part of theFaculty of Science is housed in a modern building with excellent labs and technical facilities. Surrounded by several national research institutes and with our partners at the Vrije Universiteit (VU) Amsterdam the institute is part of a strong physics centre of international standing.

You will be based at GRAPPA an internationally recognized hub in gravitation astroparticle physics and cosmology. GRAPPA hosts experts in gravitational waves numerical relativity multimessenger astrophysics and dark matter and collaborates with LIGO/Virgo/KAGRA LISA and the Einstein Telescope communities.

If you feel the profile fits you and you are interested in the job we look forward to receiving your application.
