Manchester is the only UK Physics department to be both in the top five for the volume of world-leading and internationally excellent research, and to have the maximum rating for teaching and student support. Research is based in four divisions: Accelerator, Nuclear and Particle Physics; Condensed Matter, Atomic and Biological Physics; Jodrell Bank Centre for Astrophysics; and Theoretical Physics. The School operates the world-renowned Jodrell Bank Observatory and also has extensive physics laboratories and computing facilities. Academics work in collaboration with physicists and astronomers worldwide. For further information, please consult www.physics.manchester.ac.uk. The Jodrell Bank Centre for Astrophysics (JBCA) The Jodrell Bank Centre for Astrophysics (JBCA) is one of the largest astronomy and astrophysics groups in the UK. There are 27 academics working on a range of astrophysical research projects with technological, observational and theoretical elements. The group contains an additional ~130 engineers, experimental officers, PDRAs, students and administrative staff. The main research groups are: Technology; SKA; Cosmology and Extragalactic Astronomy; Pulsars; and Stars, Sun and Planets. The University of Manchester lead the Signal and Data Transport Consortium for the pre-construction phase of the SKA and in addition lead the Non- Imaging Processing development work-packages. The JBCA operates e-merlin, and the UK ALMA Regional Centre Node. It is one of the largest astronomy groups in the UK. The JBCA is funded through UK and EU research councils, as well as ESA. The JBCA is located in the Alan Turing Building, near the centre of Manchester. The staff and students also make use of the facilities at the Jodrell Bank Observatory, South of Manchester. For further information, please consult www.manchester.ac.uk/astrophysics. Jodrell Bank Observatory The Jodrell Bank Observatory is operated by the School of Physics and Astronomy, and has tight links to the JBCA. It is home to the 76-m Lovell Telescope, the third largest fully steerable radio telescope in the world, used for world-leading research on pulsars and used as part of the European VLBI Network and the e-merlin network in the UK. The e-merlin network, which combines 7 radio telescopes with a maximum separation of 217km in the UK to produce radio images with comparable resolution to the Hubble Space Telescope, and has been upgraded with new receivers, optical fibre links and a new correlator is also operated from Jodrell Bank. Staff at Jodrell Bank operate, maintain and develop these facilities and are involved in a range of technical and observational projects. The Jodrell Bank Discovery Centre located at the Observatory (run as a distinct operation by the University of Manchester) attracts over 130,000 visitors per year. It is rapidly becoming a premier venue for scientific and cultural events, including Jodrell Bank Live and the BBC's Stargazing Live.
The headquarters of the international SKA Organisation is now located in a new building at JBO and is taking advantage of these inspiring surroundings to provide a dynamic workplace in a rural environment, 20 miles south of the main University campus.
