Description
Cool molecular hydrogen H2 may be the ultimate possible constituent to the Milky-Way baryonic hidden matter. I will describe a new way to search for such transparent matter in the Galactic discs and halo, through its diffractive and refractive effects on the light of background stars.
I will show that a mini-survey of a few hours with the telescope of the Vera Rubin Observatory, consisting in filming a single field (in the LMC or the SMC) at the rate of a few images per minute has the unique potential to discover (or exclude) interstellar scintillation due to transparent turbulent clouds in the halo.
