Descripción
The authors present some results from the Two Micron Galactic Survey (TMGS), a project which has been running for the past five years at the IAC, mapping extended areas of the galactic plane and bulge with a dedicated IR camera. With the analysis made so far they have found a giant star-formation region which strongly suggests the existence of a central galactic bar, whose receding end is found at l = 15° to 28°. This region contains some of the most luminous IR stars in the Galaxy. Also the inner distribution of the stars on the plane shows that the vast majority of these belong to the young and old disk population and to a well defined inner bulge, with almost no stars found at the galactic plane in the classical spherical distribution of the bulge.
