Title: Gas fuelling of supermassive black holes
Abstract: Supermassive black holes grow via the accretion of gas from their surroundings. This gas supply must originate in the black hole host galaxy or its immediate environment but the physical mechanisms that transport the gas to the supermassive black hole are still not understood. A plentiful gas supply is also essential to fuel the active phases of supermassive black holes (Active Galactic Nuclei) and their strong energetic output. In this talk I will discuss our current knowledge of gas transport to the black hole and the type of observations that allow us to make progress in this field. I will also show results of our recent studies where we used spatially-resolved observations to model the gas dynamics and identify the origin of the black hole gas supply.
