Multi-messenger astrophysics

Binaries consisting of two neutron stars or a neutron star and a black hole, will eventually merge due to orbital decay through the emission of gravitational radiation. The mergers themselves release vast amounts of energy, which is thought in some cases to lead to the production of short-duration gamma-ray bursts. They also expel highly radioactive neutron-rich nuclei, which will decay to form the stable r-process elements (such as gold and platinum), while powering an explosion known as a kilonova. Finally, these systems, as they merge, produce gravitational waves that can be detected using the current generation of terrestrial detectors.

In Leicester we have long been at the forefront of research on astrophysics transients, and have led successful observational and theoretical campaigns to advance the understanding of binary mergers, including making the first kilonova discovery in 2013, and being centrally involved in the discovery of the first electromagnetic counterparts to the neutron star binary merger, GW170817.

The project will involve searches for, characterisation of, and modelling of future kilonovae and the relativistic jets found accompanying gravitational wave detections and/or short-duration gamma-ray bursts, using a range of ground- and space-based facilities, such as VLT, Swift, SVOM, JWST, HST. With the gravitational wave network intended to restart observations in spring 2023, this project is particularly timely.
