Reddening and metallicity maps of the Milky Way Bulge from VVV and 2MASS. I.The method and minor axis maps
Galaxy: bulge - ISM: dust, extinction - stars: abundances
2011/10/18
We present a method to obtain reddening maps and to trace structure and metallicity gradients of the bulge using data from the recently started ESO public survey Vista Variables in the Via Lactea (VVV...
We analyzed the distribution of the RC stars throughout Galactic bulge using 2MASS data. We mapped the position of the red clump in 1 sq.deg. size fields within the area |l|<=8.5deg and $3.5deg<=|b|<=...

Spiral Galaxies：Requirements for accurate Photometric Bulge/Disk Decomposition。
The Milky-Way bulge is studied through calculating the galactocentric
orbits of imaginary bulge stars for initial conditions simulating the bulge.
