Research Assistant/Amanuensis in Mission Development for X-Ray Astrophysics

KTH Royal Institute of Technology, School of Engineering Sciences

KTH Royal Institute of Technology in Stockholm has grown to become one of Europe’s leading technical and engineering universities, as well as a key centre of intellectual talent and innovation. We are Sweden’s largest technical research and learning institution and home to students, researchers and faculty from around the world. Our research and education covers a wide area including natural sciences and all branches of engineering, as well as architecture, industrial management, urban planning, history and philosophy.

Job description

Stellar-mass black holes and neutron stars provide a means to study extreme physical environments. Since they are too small and distant to be directly imaged, our knowledge stems from studying the highenergy (e.g. X-ray) radiation which they emit, and inferring physical attributes from spectral and timing measurements. Interpretations are often model-dependent which, ultimately, limits our knowledge. A
new approach is to measure the polarisation of the X-ray radiation. Observations are systematically different from those conducted today and can be used to break model degeneracies.

One of the highlights of astrophysics during this decade will be establishing X-ray polarimetry as a new window on the high-energy universe. Our group at KTH develops X-ray polarimeters for astrophysics, and has made pioneering observations of celestial objects from a balloon-borne platform in the stratosphere. We are now preparing to further develop instrumentation to allow observations from a satellite which will orbit the earth.

A number of optimisations and trade-offs are needed to go from a balloon-based mission to a spacebased mission. An important aspect is to understand and characterise how the background radiation which is present in space will affect the mission. The project will involve performing computer simulation studies of the proposed space mission using Geant4 - a software framework to describe the interactions of particles and radiation with matter. The results of this study will be fed into the mission design, in order to mitigate background radiation effects and achieve a high measurement sensitivity.

What we offer

  • A position at a leading technical university that generates knowledge and skills for a sustainable future.
  • Engaged and ambitious colleagues along with a creative, international and dynamic working environment

Qualifications

Requirements

You should be admitted to education at the basic or advanced level at KTH.
