| Abstract: |
The origin of the molecular clouds orbiting SgrA* is one of the most debated questions about our Galactic Centre. In this contribution, we present the hydrodynamic simulation of a molecular cloud infalling towards SgrA*, performed with the adaptive-mesh-refinement code RAMSES. Through such simulation, we show that the circumnuclear disc, the +20 km/s cloud and possibly the +50 km/s cloud could be originated from the same tidal disruption episode, occurred less than 1 Myr ago. We also show that recent star formation is to be expected in at least the +20 km/s cloud, as also suggested by recent observations. |
