The visibility of the Galactic bulge in optical surveys. Application to the Gaia mission
A. C. Robin, C. Reylé, S. Picaud +1
The bulge is a region of the Galaxy which is of tremendous interest for understanding Galaxy formation. However, measuring photometry and kinematics in it raises several inherent i…
3D outer bulge structure from near infrared star counts
S. Picaud, A. C. Robin
We attempt to study the characteristics of the different stellar populations present in the Galactic central region. A Monte Carlo method is used to simultaneously fit 11 thin disc…
A synthetic view on structure and evolution of the Milky Way
A. C. Robin, C. Reylé, S. Derrière +1
Since the Hipparcos mission and recent large scale surveys in the optical and the near-infrared, new constraints have been obtained on the structure and evolution history of the Mi…
Stellar density distribution in the NIR on the Galactic plane at longitudes 15-27 deg. Clues for the Galactic bar ?
S. Picaud, A. Cabrera-Lavers, F. Garzon
Garzon et al. (1997), Lopez-Corredoira et al. (1999) and Hammersley et al. (2000) have identified in TMGS and DENIS data a large excess of stars at l=27 deg and b=0 deg which might…
