This research is aimed at training the student to take advantage of future galaxy studies with the Square Kilometer Array (SKA), which will be the largest radio telescope in the world. Galaxy clusters are assembled from the infall of individual galaxies as well as galaxy groups. These individuals and groups in turn may fall in along filaments where the pre-processing of the galaxies has occurred. Observations of the neutral atomic hydrogen (HI) content of galaxies using largre radio telescopes are key to identifying recent and ongoing interactions between galaxies and their environment, as well as predicting the quenching of star formation due to these interactions.
About the project
This research project will focus on how galaxy clusters are assembled, and how their assembly impacts the tranformation of galaxies in the cluster environment. The PhD candidate will use data from state-of-the-art telescopes including MeerKAT, a precursor to the SKA, and optical imaging from DECam to study the impact of gas loss in galaxies through different environmental mechanisms: from galaxy-galaxy interactions to ram pressure stripping, in the Antlia Cluster and its surrounding filaments. The student will learn radio interferometric data reduction and synthesis imaging, and the research will involve identifying where galaxies live in the cluster/filament/field/substructure environments, quantifying and classifying the properties and evolutionary state of the galaxies, and comparing with control samples and what is previously known from the literature. Depending on the background and interest of the student this can lead to further follow-up observations at other wavelengths, or to detailed comparisons with cluster formation in simulations. The candidate will have access to high performance computing resources and join a vibrant international collaboration of researchers with multi-wavelength expertise on galaxy clusters.
About the department
Onsala Space Observatory is the Swedish national facility for Radio Astronomy, hosting the Nordic ALMA Regional Centre, the Swedish SKA Regional Center (SWE-SRC), as well as 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. Physically, we are situated both at the observatory in Onsala south of Gothenburg, and at the main Johanneberg campus at Chalmers in Gothenburg.
Major responsibilities
Your major responsibilities 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, chemistry, physics, or scientific computing, by July 2023. 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. In addition, excellent writing and communication skills in English are required.
Contract terms
Full-time temporary employment.
Expected start is Fall 2023. The starting salary for PhD positions is approximately 31,000 SEK per month. Expected position duration is 4 years which include course work corresponding to 1 year.
