MASGOMAS project: building a bona-fide catalog of massive star cluster candidates

MASGOMAS (MAssive Stars in Galactic Obscured MAssive clusterS) is a project aiming at discovering OB stars in Galactic, dust enshrouded, star-forming massive clusters (Marin-Franch et al. 2009, A&A 502, 559). The project has gone through different phases of increasing automatization, that have allowed us to discover massive clusters like MASGOMAS-1 (Ramirez Alegria et al. 2012, A&A 541, A75) (with M≈20,000 M⊙).
