Description
We have conducted a very high resolution simulation of a Milky-Way like galaxy including star formation, radiative feedback, etc. This AMR simulation follows all scales from the dark matter halo down to 0.05pc simultaneously (i.e., not a zoomed-in re-simulation). I will present results focused on the turbulence, central fueling, star-formation regimes, in the 200pc region around the super-massive black hole. Structures and physical conditions witnessed in this simulation are very similar to the ones observed in the central region of the Milky Way itself, thus shedding light on the formation (and destruction) of the central ring, star formation regimes and time-scales, and feeding of the central dark mass. The resonant structures are quickly evolving via instabilities, also triggering the formation of new stars, then leading to significant feedback and nuclear inflows.
