Probing 3D Density and Velocity Fields of ISM in Centers of Galaxies with Future X-Ray Observations

Presence of large quantities of molecular gas in the vicinity of Sgr A* opens the possibility for synergetic studies of the supermassive black hole's past outbursts and the fundamental properties of the molecular clouds themselves. The full potential of this synergy can only be exploited with the next generation of X-ray observatories
