Herschel water maps towards the vicinity of the black hole Sgr A*

We study the spatial distribution and kinematics of water emission in a∼8×8 pc^2 region of the Galactic Center (GC) that covers the main molecular features around the supermassive black hole Sagittarius A∗(Sgr A∗). We also analyze the water excitation to derive the physical conditions and water abundances in the Circumnuclear Disk (CND) and the “quiescent clouds”.
