Gravitational Waves

Gravitational Waves are ripples in the curvature of spacetime as predicted by Einstein in his theory of General Relativity. Sources include compact binaries, spinning non-axisymmetric objects and supernovae.

Accretion onto Compact Objects

A major area of research in X-ray astronomy is the accretion of matter on to black holes and neutron stars in the context of AGN and galactic X-ray binaries. Accretion is an energetic process and can give high luminosities.

Forming Supermassive Black Holes

Black holes are among the most fascinating phenomena thought to exist in the Universe. A black hole is a region of space in which the gravitational field is so powerful that nothing, not even light, can normally escape.

Gravitational Lensing

Gravitational lensing is used to determine the masses of lensing galaxies and clusters and to study more distant galaxies that can be magnified by a factor of more than 20.

X-ray Group

X-ray astronomy research in Cambridge is carried out by an active X-ray Astronomy group whose research focusses on accretion on to compact objects and the physics of clusters of galaxies.
