Waiting for Starlight

Powerful jets of high-speed material are pictured in blue in this computer simulation of an exploding star that harbors a gamma-ray burst. Davide Lazzati uses three-dimensional computer simulations to shed light on the dynamics of these energetic outflows, which stream out of their progenitor star (in red and orange). The jets eventually escape from the dense and cold stellar material and convert their energy into gamma-ray radiation that can be detected with telescopes. (From Lopez-Camara, Lazzati, Morsony, & Bergelman 2013)

Davide Lazzati tries to make sense of violent bursts that shine from the far reaches of the universe
