The Onsala Space Observatory (OSO) is one of the pioneers of VGOS, and is currently the only site with a fully operational VGOS twin telescope installation.
VGOS is of major importance for maintaining reference frames, both the international celestial reference frame (ICRF) and the international terrestrial reference frame (ITRF). These two reference frames and the transformation between them, usually expressed as earth orientation parameters (EOP), are needed by science and society to, e.g. monitor the Earth's ever-changing geodynamical state, from earthquakes to climate change. Accurate and reliable reference frames are thus a pre-requisite for an improved understanding of global change processes and a sustainable development of society.
Project description
We are looking for a highly motivated PhD student to work in a new project that is funded by the Swedish Reserarch Council. The goal of the project is to develop the Onsala twin telescopes (OTT) into a near real-time instrumentation so that the currently two most important limiting factors for VGOS can be addressed. The latter are a) radio source structure and variability and b) instrumental stability of the VGOS telescopes. To address these aspects, an automated near real-time pipeline shall be developed that allows using the OTT for a routine monitoring of the flux density of the radio sources that are used in VGOS, as well as to continually measure the local baseline between the OTT. The derived radio flux density information shall be collected in public, open databases that will be continually updated and can be used in planning new geodetic and astrometric VLBI sessions. The observations shall also be used in a purely geodetic sense to routinely monitor the geodetic baseline between the OTT, allowing to charaterize and model the stability of VGOS instrumentation.
Information about the division
The PhD position is in the research group for Space Geodesy and Geodynamics. Together we work to increase knowledge on how to best achieve a long-term sustainable planet. Our main working places are the Onsala Space Observatory, 40 km south of Gothenburg, and Chalmers University of Technology in Gothenburg.
Major responsibilities
Your major responsibilities as a PhD student are to pursue your own doctoral studies to become an independent researcher. You are expected to develop and conduct your own research at the frontier of VLBI for geodesy and astrometry. You are expected to develop your own scientific concepts and communicate the results of your research verbally and in writing, primarily in English. You are expected to write a licentiate thesis within 2-3 years and to defend your doctoral thesis within 4-5 years. The position generally may also includes teaching on Chalmers' undergraduate level or performing other duties corresponding to 20 per cent of working hours.
Qualifications
To qualify as a PhD student, you must have a master's level degree corresponding to at least 240 higher education credits in Geodesy, Astronomy, Engineering Physics, Geophysics, Physics or an equivalent education.
The position requires sound verbal and written communication skills in English. If Swedish is not your native language, Chalmers offers Swedish courses.
Contract terms
Full-time temporary employment. The position is limited to a maximum of five years.
