The massive black hole in our Galactic centre, Sgr A*, accretes only a small fraction of the gas available at its Bondi radius. The physical processes determining this accretion rate remain unknown, partly due to a lack of observational constraints on the gas at distances between ∼10 and ∼105 Schwarzschild radii (Rs) from the black hole. Recent infrared observations identify low-mass gas clouds, G...
