Abstract

In the era of rapid and accurate localisation of Gamma Ray Bursts by the Swift satellite, high quality early time multi-wavelength light curves, obtained by space and ground-based robotic telescopes, have shown that the standard 'smooth temporal power law decays' typical of late-time afterglow emission can be substantially modified at early times by e.g. energy injection from long-lived central engines, and/or interactions between the ejecta and clumps in the surrounding circumburst medium. Well-sampled optical light curves (covering a wide range in time, brightness and redshift) together with early-time polarimetry provide a powerful probe of the physics of GRBs, their ejecta and their environments. Here we summarise the GRB followup programme being conducted on a network of the world's three largest robotic telescopes that aims to obtain early-time multicolour photometric and polarimetric measurements crucial for the understanding of GRB physics.
