High-speed astrophysics with ULTRACAM and HiPERCAM

ULTRACAM and HiPERCAM are high-speed optical cameras that can take hundreds/thousands of CCD images per second simultaneously in three/five colours, respectively. They have been mounted on the largest optical telescopes in the world to study rapid variability in the Universe, including white dwarfs, neutron stars, black holes, exoplanets, brown dwarfs, AGN, FRBs, GRBs and occultations by Solar System objects. Both instruments were built by a consortium led by Sheffield. The aim of this PhD project will be to exploit these unique instruments. A number of possible projects are available, including: optical counterparts of FRBs and pulsars, optical observations of the JWST Time-Domain Field
