Postdoctoral Research Assistant in Galaxy Evolution and Photometric Redshifts with VIDEO and Euclid

Astrophysics

Grade 7: 30,738 - 37,768 p.a

The Observational Astrophysics group at Oxford is one of the largest in the country encompassing research in a wide range of projects on galaxy formation and galaxy evolution. Our observational work makes use of world-class facilities and benefits from a strong in-house instrumentation program. We are a member of the LSST science collaboration and are very active in the scientific preparation for Euclid and the SKA.

Applications are invited for a postdoctoral position in the scientific exploitation of the VISTA Deep Extragalactic Observations (VIDEO) Survey (www-astro.physics.ox.ac.uk/~video/public/Home.html) led by Professor Matt Jarvis at the University of Oxford. The VIDEO survey is a 12 sq.degree, Z,Y,J,H,Ks survey specifically designed to enable galaxy and cluster/structure evolution to be traced as a function of both epoch and environment from the present day out to z=4, and AGN and the most massive galaxies up to and into the epoch of reionisation.

In particular, we are seeking someone to study the formation and evolution of galaxies and AGN. The VIDEO survey reaches the same near-infrared depth as the proposed Euclid sky survey and the successful candidate will also have the opportunity to be involved in the development of photometric redshift techniques based on Gaussian Processes, in collaboration with the machine learning group led by Professor Steve Roberts.

Some interest in linking optical and near-infrared surveys to radio surveys such as those underway with LOFAR, the JVLA and MeerKAT in the future would also be an advantage.

This project is funded by an award from the Science and Technology Facilities Council and the UK Space Agency. The position is available for a fixed-term of up to 2 years in the first instance, with a possible extension to a third year dependent on performance and funding, with a start date as soon as possible.

The successful candidate will have or be about to receive a PhD in a relevant area of astronomy/astrophysics and should have a demonstrated capacity for independent work and be capable of initiating research in a lively group. The postholder will have the opportunity to teach.

A benefits package and a research budget for travel and other expenses will be provided.

Informal enquiries can be made directly to Matt Jarvis (matt [dot] jarvis [at] physics [dot] ox [dot] ac [dot] uk).

All applications must be received by 12.00 noon on Wednesday 2nd March 2016.

Euclid Mission Postdoctoral Research Assistant and Beecroft Fellow

Astrophysics

Grade 7: 30,738 - 37,768 with a discretionary range to 41,255 p.a.

Applications are invited for a postdoctoral research position, funded primarily by the UK Space Agency for the development and implementation of the Euclid mission?s Weak Lensing Science Ground Segment. Particular aims are to develop methods for modelling the point spread function (PSF), reconstructing an accurate PSF model from in-orbit data, and developing methods for incorporating the PSF into weak lensing shear measurement. A fraction of time will be reserved for research in related areas of either astronomical instrumentation or astrophysics and cosmology.

Knowledge of the Euclid PSF is crucial to the success of the mission?s weak lensing survey. Oxford has led the development of PSF modelling methods for the Euclid PSF, including wavefront phase recovery methods to be applied to in-orbit data, and the generation of simulated PSFs. The postholder will be expected to build on the existing work; to develop, test and verify both current and new algorithms; to develop new ideas on measuring the PSF and utilising it in the weak lensing shear measurement context; and to build and validate the primary Science Ground Segment PSF modelling pipeline. The postholder would become a member of the Euclid Consortium and would be expected to collaborate with others within the UK, Europe and the USA. The postholder would have the opportunity to become involved in other aspects of the Euclid mission?s weak lensing survey. The postholder would be expected to publish their work in refereed science journals and in Euclid technical notes and to attend and present results and national and international meetings as appropriate.

The postholder would have up to 25% of their time available for further research in other related areas, in either astronomical instrumentation, astrophysics or cosmology.

The post is fixed-term for 2 years in the first instance, with the possibility of further extension depending on performance in the post and on availability of funding.

The successful candidate will have obtained, or expect shortly to obtain, a PhD in astronomical instrumentation and/or astrophysics and cosmology research. The postholder will have the opportunity to teach.

Only applications received by 12.00 midday on 1 April 2016 can be considered.

Please also look at the Job Description and Person Specification and apply online.

Application Deadline: 1 April 2016 by 12:00 midday
