A large fraction of the matter content of the universe is thought to be dark matter. There are numerous experiments around the world that aim to detect dark matter or infer its properties directly or indirectly, though to date there has not yet been a conclusive direct experimental detection of a dark matter interaction. Dr […]
It is generally believed that the rings around the planet Uranus were discovered during an occultation experiment in 1977. Remarkably, however, the first possible observations of a ring around Uranus may have been made by William Herschel some 180 years earlier. This talk discusses the evidence, and then considers the factors that might have changed […]
Dr David Tsang was born in Canada, and did his undergraduate degree in Engineering Physics and Maths at the University of British Columbia, followed by a Masters and PhD in Physics at Cornell University. He has worked as a research scientist at Caltech, McGill University, the University of Maryland and the University of Southampton. He […]
Pleae note that this is an invitation only event.
Dr Vicky Scowcroft has kindly agreed to reschedule her lecture of 1st February which had to be cancelled because of the snow. Abstract: For centuries, variable stars have been crucial in the study of stellar populations. Astronomers have conducted rigorous observations over many decades in order to understand the physics behind their varying brightnesses. These […]
Variety in astronomical orbits Gravitation dominates the dynamics of the Universe on scales larger than a few kilometres, and so orbital motion is the basic motion of bodies in the Universe. The variety of orbital motions is much wider than the set of elliptical shapes that are used as an approximation in the Solar System. […]
Herschel: A Space Observatory’s Legacy Dr Chris North will recap the Herschel Space Observatory, in terms of the mission design and its science goals, and the discoveries that have been made from it. From planets to supermassive galaxies, the range of discoveries is vast. The science continues apace, even nearly 10 years after Herschel’s launch, […]
Abstract: For centuries, variable stars have been crucial in the study of stellar populations. Astronomers have conducted rigorous observations over many decades in order to understand the physics behind their varying brightnesses. These unique objects come in many flavours, some changing regularly and predictably, with others changing erratically, sometimes lying dormant for years at a […]
