Autonomous spectrographic system to analyse the main elements of fireballs and meteors
Earth, Planets and Space, 2018 We present a meteor observation system based on imaging CCD cameras, wide-field optics and a diffraction grating. This system is composed of two independent spectrographs with different configurations, which allows us to capture images of fireballs and ...

Hydrodynamics from free-streaming to thermalization and back again
Physics Letters B, 2020 We study the evolution of the Knudsen and Reynolds numbers in (0+1)-dimensionally expanding fluids with Bjorken symmetry for systems whose microscopic mean free path rises more quickly with time than usually assumed.

Thermalization, viscosity and the averaged null energy condition
Journal of High Energy Physics, 2018 We explore the implications of the averaged null energy condition for thermal states of relativistic quantum field theories. A key property of such thermal states is the thermalization length.
