Unraveling the formation history of the Galaxy with RAVE
Final Report Abstract
The RAdial Velocity Experiment (RAVE) is a spectroscopic high latitude survey of the Milky Way with the major aim at disentangling the formation history of the Milky Way. The RAVE survey focuses on target is the magnitude range 9 < I < 13, the wavelength range between 8410 and 8795 A˚ at an average resolution of R=7500. Data for the RAVE survey were collected between April 2003 and December 2012. The SPP project contributed considerably to the data collection and analysis of RAVE. By May 2012, some 530,000 spectra for 450,000 individual targets have been amassed, making RAVE the largest spectroscopic survey of the Milky Way performed to date. Data products of RAVE have been published in several data releases and include radial velocities, stellar parameters, distances and abundances of up to seven chemical elements (Mg, Al, Si, Ca, Ti, Fe, and Ni). Science applications of RAVE include the dynamical structure of the nearby Galactic disk, the dynamical and chemical separation of the main galactic components – thin disk, thick disk and halo – and the age-metallicity and age-metallicity-velocity relation in the solar neighbourhood. Furthermore the project resulted in the discovery of a new tidal stream (Aquarius stream). Modelling of the stream properties indicates that the Aquarius stream is dynamically very young. It is the closest tidal stream discovered to date. The project was complemented by a simulation campaign that aimed at creating realistic models of the Milky Way galaxy in cosmological simulations. Considerable progress was made to that respect by using advanced feedback models. One application of these models was to investigate whether the population of hyper-velocity stars can be accounted for by the tidal disruption of an infalling dwarf galaxy.
