		| Abstract: | 
		The base of the Scutum arm is a Galactic region with a high density of red supergiant (RSG) stars, grouped in a few clusters which have similar ages, positions and radial velocities. We have performed an extensive survey using the multi-object spectrograph AAOmega, looking for new RSGs along the galactic plane from l∼24° to 30°. We have observed >1600 candidates, and identified them through an extensive study of the statistical behavior of RSG spectra, finding ∼200 new RSGs. |
