Hubble Space Telescope image of the "Cat's eye nebula", which is a star in one of its final stages. At this point it throws off most of its mass and leaves behind an object called a white dwarf, visible as the white point at the centre of the nebula. We do lots of work here on white dwarfs.
Quantum mechanics rests on the wave-particle duality. With such graphs of multifractal exponents we study how quantum interference can turn a metal (top sheet) into an insulator (bottom sheet) - [Prof. Roemer]
Material characterisation is at the forefront of a wide range modern technological innovations and requires the brightest x-ray beams and complex sample environments such as those provided by the XMaS beamline located at the European Synchrotron Radiation Facility - [Dr Hase]
Hot, one million K plasma loops in the corona of the Sun, observed with the Solar Dynamics Observatory - [Prof Nakariakov]
V838 Mon, a star located about 20,000 light years from Earth, captured by Hubble Space Telescope. It underwent a large outburst a few years ago which may have been caused by the merger of two stars - [Prof Marsh]

According to general relativity spinning objects twist the spacetime around them. This could be an explanation for CP violation - [Dr Hadley] more...
The Rosette Nebula, a region of star formation with molecular gas and dust, lit up by its young stars. The image is part the first detailed map of the galactic plane, in which Warwick astronomers are involved.
Published in the journal Nature, a team including Warwick astronomer Peter Wheatley has discovered a giant comet-like tail of hydogren gas evaporating from a Neptune-sized exoplanet. The gas is thought to be boiled off by X-rays from the parent star and then swept away by radiation pressure. The tail was revealed in Hubble Space Telescope observations in which 56% of the star is covered by the tail in ultraviolet light. The planet is losing its atmosphere at a rate of 1000 metric tonnes per second, having narrowly escaped total evaporation by the intense X-ray irradiation it suffered when its parent star was young and active.

Congratulations to Robb Johnston for winning the inaugural Papin Prize for “Contribution to Infrastructure” at the 2015 Higher Education Technician Summit, which celebrated the skills, talent and experience of technicians from M5 Universities. The Papin prizes recognise the invaluable role played by technicians and are named after Denis Papin, a 17th century technician who worked with Robert Boyle and was one of the first technicians to publish in his own name.
Robb was nominated by the department for the longstanding contribution he has made to Physics.
Professor Valery Nakariakov has been awarded the 2015 Payne-Gaposchkin medal and prize by the Institute of Physics for his leadership and major contribution to the discovery of magnetohydrodynamic (MHD) activity of the solar corona. His research has led to transformative changes in our understanding of the solar atmosphere, and to the creation and successful implementation of a new branch of solar physics - MHD coronal seismology.
This award is named after Cecelia Payne-Gaposchkin who was the first person to show that the Sun is mainly composed of hydrogen, contradicting accepted wisdom at the time. It is made biennially by the IOP for distinguished research in plasma, solar or space physics.
