Gaia capability of constraining the MW spiral arms from the disc velocity distribution
DAM and IEEC-UB, Institut de Ciencies del Cosmos de la
Universitat de Barcelona, Spain
The resonances of the bar and the spiral arms of the Milky Way (MW) can induce kinematic groups in the local stellar velocity distribution. The Gaia mission is going to provide us with accurate information on the velocity distribution for an extended region of the Galactic disc. Here we aim to evaluate the Gaia capabilities to constrain the non-axisymmetric large-scale structure of the MW from the observed velocity distributions.
