Artist’s impression of the powerful winds blowing from the bright X-ray source GX13+1. The X-rays are coming from a disc of hot matter, known as an accretion disc, that is gradually spiralling down to ...

The James Webb Space Telescope has determined that massive planets can be formed through the bottom-up accretion process. The ...

My research group studies the accretion process onto black holes, in order to understand how they grow and to develop tests of strong field general relativity. We make detailed predictions for the ...

Starting from the upper left and moving clockwise from large to small scales: upper left —"spiral-like" system; upper right — "bar-like" structure; lower right — rotating infalling envelope; lower ...
