Description of the research project:
Martin Aubé's research focuses on the theoretical modeling and remote sensing of the artificial brightness of the night sky. This diffuse light, often associated with light pollution, constitutes a luminous veil that curtail the observation of low brightness astronomical objects. Aside of the influence of light pollution on astronomical observations, Martin Aubé is also studying its impacts on the environment and on human health. More exactly, Martin Aubé's research is based on the physical behavior of the radiative transfer of artificial light in the environment and the atmosphere, attempting to consider as closely as possible the various complex interactions involved. Specifically, Martin Aubé considers the propagation of light using a hyperspectral approach while solving light diffusion on particles up to the second order. From a modeling point of view, these two aspects require high-performance computing resources in order to solve the problem within a reasonable timeframe. Initially developed for the Observatoire du Mont-Mégantic, Martin Aubé's modeling and remote sensing approach was exploited to characterize the brightness of the sky and regulate lighting standards for many world-class astronomical sites such as KPNO, FLWO, Roque de los Muchachos or Observatorio El Leoncito.
