Postdoctoral Research Assistant in CMB Polarised Foregrounds

Astrophysics

Applications are invited for a Postdoctoral Research Assistant in CMB Polarised Foregrounds. The post is available initially for a fixed-term duration of 24 months.

This project is to use data from the C-Band All-Sky Survey (C-BASS) and other CMB experiments to improve the separation of CMB foregrounds, leading to improved measurements of cosmological parameters, and a better understanding of foreground emission mechanisms. We also plan to design and simulate future experiments for measuring CMB foregrounds, and collaborate with groups designing new CMB experiments such as LiteBIRD.

The successful candidate will work on analysis and exploitation of data from the C-BASS survey, using existing software and also writing new code, to produce better measurements of cosmological parameters from CMB data. They will also do simulations to help plan new CMB foregrounds experiments. The postholder will have the opportunity to teach.

Applicants should hold, or be close to obtaining, a doctorate in physics or a related field and ideally a strong background in CMB observational cosmology, with a strong background in scientific data analysis software. Previous experience in the field of CMB foregrounds will be an advantage. Candidates are expected to demonstrate the ability to independently manage a research area within the overall

Postdoctoral Research Assistant in Receiver Development for SKA

Astrophysics

Applications are invited for a Postdoctoral Research Assistant in Receiver Development for SKA. The post is available initially for a fixed-term duration of 24 months.

Oxford University is leading the development of the Band 3/4/5 feed package for the SKA-Mid telescope of the Square Kilometre Array. This cryogenic feed system will be fitted to the 133 SKA-Mid dishes, providing the SKA with up to five frequency bands. The initial project is to build and test a prototype feed package with two bands installed, and test it on the SKA prototype dish antenna in South Africa. There will also be the opportunity to become involved in a number of other projects in advanced radio astronomy instrumentation, including CMB foregrounds experiments, and new radio telescopes in Mexico and Thailand.

The successful candidate will work on modelling and testing the performance of the system components, and the integration and testing of the complete SKA receiver. This will also include modelling (using software such as GRASP) and testing of the receiver performance installed on an SKA dish antenna. They will also assist with the production of a full document set describing the receiver, ready for mass manufacture. The postholder will have the opportunity to teach.

Applicants should possess, or be close to obtaining, a doctorate in physics, electrical engineering or a related field. Experience with working with cryogenic radio receivers is essential, as is familiarity with RF and microwave test equipment and techniques. Previous experience with electromagnetic simulation and CAD software packages would be an advantage. Candidates are expected to demonstrate the ability to independently manage a development area within the overall project, to contribute to and communicate with SKA project via papers, technical documents and presentations.

Astrophysics

Applications are invited for a Postdoctoral Research Assistant in Receivers for Radio Astronomy. The post is available initially for a fixed-term duration of 24 months.

As part of a programme funded by the Newton Fund for international development, Oxford University is collaborating with several institutions in Mexico to convert a 32m ex-telecoms antenna at Tulancingo, Mexico, to a radio telescope. This will provide the Mexican astronomical community with a state-of-the-art research facility, and will also facilitate development goals of skills and knowledge transfer and human capital development. The successful candidate will work on the design and implementation of a cryogenic receiver system, including a digital backend, for the Tulancingo telescope, and will lead organising and delivering a set of training sessions for Mexican engineers and scientists in Oxford and in Mexico. They will the lead the commissioning of the receiver in Mexico and the handing of the system over to the Mexican institutes for long-term operation. The postholder will have the opportunity to teach.

Applicants should possess, or be close to obtaining, a doctorate in physics, electrical engineering or a related field. Experience with working with cryogenic radio receivers is essential, as is familiarity with RF and microwave test equipment and techniques, and previous experience with FPGA systems. Previous experience with satellite communications antennas, electromagnetic simulation and CAD software packages would be an advantage. Candidates are expected to demonstrate the ability to independently manage their role within the overall project, including managing the receiver development budget, to communicate via papers, technical documents and presentations.

Senior Researcher in Digital Receivers for Radio Astronomy

Astrophysics

Applications are invited for a Senior Researcher in Receivers for Radio Astronomy. The post is available initially for a fixed-term duration of 2 years.

Oxford University is collaborating with the National Autonomous University of Mexico (UNAM) to develop advanced radio astronomy instrumentation, as part of a programme funded by the Newton Fund for international development. This project aims to take digital systems developed for the Square Kilometre Array and apply them to create new digital backends for the Large Millimetre Telescope (LMT), a 50m telescope in Mexico. This will provide the Mexican astronomical community with a state-of-the-art research facility, and will also facilitate development goals of skills and knowledge transfer and human capital development. There will be the opportunity to also become involved in other radio astronomy instrumentation projects in Oxford, including the Square Kilometre Array, the C-Band All-Sky Survey, and future planned experiments in CMB foregrounds.

The successful candidate will work on the design and implementation of digital spectrometer backends for two receivers on the LMT. They will liaise with the Mexican PI at UNAM and supervise two Mexican postdocs, ensuring that knowledge and skills are transferred to the Mexican community. They will lead the commissioning of the digital systems in Mexico and the handing of the system over to the Mexican institutes for long-term operation. Applicants should possess a doctorate in physics, electrical engineering or a related field, with some postdoctoral experience. Experience with working with FPGA-based signal processing systems is essential, as is familiarity with RF and microwave test equipment and techniques. Previous experience with radio astronomy signal processing systems, electromagnetic simulation and CAD software packages would be an advantage. Candidates are expected to demonstrate the ability to independently manage a complex technical project with international collaborators, including managing budgets, and to communicate via papers, technical documents and presentations.
