PhD student position in Astronomy o dig into the details of how complex geometric and physical information can be derived
Are you fascinated by the fact that we can observe molecules on other planetary bodies or where new stars and planets are forming and learn more about the origin of life? Chalmers is looking for a motivated and analytical PhD candidate who wants to dig into the details of how complex geometric and physical information can be derived from such observations. You will have the opportunity to work on theoretical modeling that is closely connected to planned and ongoing space missions, in particular ESAs JUICE mission to Jupiter.
Information about the research and the division
This research project will focus on the planning and interpretation of astronomical observations, in particular upcoming observations of the thin, gaseous exospheres of water associated with the icy Galilean moons of Jupiter: Ganymede, Callisto and Europa. This water gas is very difficult to observe from ground because of Earth’s atmosphere, so the JUICE mission will carry a small sum-mm telescope (SWI) capable of observing water emission at high spectral resolution. In particular, we want to use SWI to constrain the composition of the exospheres and determine the distribution of water. The work will involve implementing sophisticated 3D structures in non-LTE radiative transfer models (e.g., LIME, RADMC-3D, Hyperion, ALI), to interpret spatially and spectrally resolved line profiles as well as emission in continuum. Using data acquired with ALMA and the recently launched JWST, there will also be opportunities to model the emission from young star forming regions. The work will be supervised by associate professors Eva Wirström and Per Bjerkeli.
As a PhD student you will be part of the Onsala Space Observatory Division of the Department of Space, Earth and Environment. Onsala Space Observatory is the Swedish national facility for Radio Astronomy, hosting the Nordic ALMA Regional Centre and also research groups in Advanced Receiver Development and Space Geodesy and Geodynamics. Astronomy and astrophysics research is hosted within two divisions at SEE, Onsala Space Observatory and Astronomy and Plasma Physics. Our members work in close connection and research covers a wide range of topics including astrochemistry, the birth and death of stars, exoplanets, formation and evolution of galaxies and the solar system. The research spans theoretical and computational studies, observational programs and instrumentation development for ground and space-based observatories. Physically, we are situated both at the observatory in Onsala south of Gothenburg and at the main Johanneberg campus in Gothenburg.
Major responsibilities
Your major responsibility as a PhD student is to pursue your own doctoral studies to become an independent researcher. You are expected to develop your own scientific concepts and communicate the results of your research verbally and in writing. The position may also include teaching at Chalmers or performing other duties corresponding to up to 20% of working hours, thereby increasing the duration of the position beyond 4 years. You are expected to write a licentiate thesis within 2-3 years and defend your doctoral thesis within 4-5 years.
Qualifications
To qualify for the position you must have completed a MSc or equivalent degree corresponding to at least 240 higher education (ECTS) credits in astrophysics, astronomy, physics, or scientific computing, by July 2022. Completed courses in astronomy and experience in programming (e.g. python, C++, Matlab), radio astronomy observational techniques, teaching, scientific writing and communication are all considered assets for the position.
Excellent writing and communication skills in English are required.
Contract terms
Full-time temporary employment for 4 years. Departmental duties in the form of astronomy outreach and/or teaching can extend the position to a maximum of 5 years. Starting date is expected as soon as possible, but no later than 1 December 2022. The starting salary for PhD positions is approximately 31,000 SEK per month.
