Astronomy and Astrophysics Group
The Astronomy and Astrophysics group at Warwick is one of the newest additions to the Department of Physics, beginning life in September 2003 with the appointment of Prof Tom Marsh. We are interested in stars and planets, how they live and how they die, and the exotic physical processes that they allow us to explore. We are an observational group and make use of a wide range of ground-based telescopes, such as ESO's Very Large Telescope (VLT) in Chile and the Isaac Newton Group of telescopes (ING) in the Canary Islands, as well as space telescopes such as NASA's Chandra and ESA's XMM-Newton X-ray observatories and the Hubble Space Telescope.
The objects we study are dynamic and can change within minutes, seconds and even milli-seconds. We specialise in the high-speed data acquisition and analysis techniques needed to track them. Members of the group have contributed to the development and exploitation of the ULTRACAM high-speed photometer, the Wide Angle Search for Planets project (WASP), and the Next Generation Transit Survey (NGTS). We are also heavily involved in the development of space missions including ESA's Exoplanet missions - PLATO (launch 2024) and CHEOPS (launch 2018).
7 May 2015: A research team led by Warwick astronomers Roberto Raddi and Boris Gänsicke have found that water delivery via asteroids or comets is likely taking place in many other planetary systems, just as it happened on Earth. Read the Warwick press release and the paper in the Monthly Notices of the Royal Astronomical Society.
14 January 2015: Warwick astronomers have begun searching for small planets around bright stars using an array of twelve robotically-controlled telescopes. The telescopes, which form a wide-field observing system called the Next Generation Transit Survey (NGTS), are designed to detect the slight dimming of a star when a planet passes across its face. The NGTS team aims to find planets the size of Neptune down to twice the size of the Earth. Dr Peter Wheatley, one of the NGTS project leaders, said "The NGTS discoveries, and follow-up observations by telescopes on the ground and in space, will be important steps in our quest to study the atmospheres and composition of small planets such as the Earth.”

08 August 2014: A research team led by Warwick astronomers Joe Lyman and Andrew Levan have investigated the locations of peculiar 'calcium-rich' supernovae, which are often seen to explode at huge distances from any nearby galaxy. They postulate the merger of white dwarf-neutron star binary systems 'kicked' from their galaxy may explain these remote locations. The Warwick press release can be found here.
