Young Stars at the Edge: Stellar Clustering in the Outer Regions of the M33 Disk
We investigate the distribution of bright main sequence stars near the northern edge of the M33 disk. Clustering on sub-kpc scales is seen among stars with ages near 10 Myr, and two large star-forming complexes are identified. ...
Insights on the Milky Way bulge formation from the correlations between kinematics and metallicity
Two main scenarios for the formation of the Galactic bulge are invoked, the first one through gravitational collapse or hierarchical merging of subclumps, the second through secular evolution of the Galactic disc. We aim ...
