We study the dynamical interaction of the G2 cloud with the accretion flowaround Sgr A* by means of three-dimensional, hydrodynamic simulations. We showthe effects of the rotating accretion flow on the evolution of G2 by projectingthe cloud density onto the plane of the sky, and extracting position-velocitydiagrams. We study a number of possible orientations of the cloud orbit withrespect to the disk. We find that once the center of mass of the cloud hascrossed the pericenter, the differences between models becomes significant.Models with the cloud counter-rotating with respect to the disk are expected toreach higher blue-shifted line of sight velocities. The spatial extent of theemission depends strongly on the cloud-to-disk inclination angle. Futureimaging and spectroscopy of G2 emission will shed light both on the structureof the Sgr A* disk and on the properties of the cloud.

Simulating the effect of the Sgr A* accretion flow on the appearance of G2 after pericenter
