Description
The study of the bulge of the Milky Way galaxy is still one of the main puzzles for the Galactic studies. Exploring stars in this region is quite challenging due to not only myriad stars which are tightly packed together in the bulge but also the interstellar dust in the galactic plane which restrict the observation. In order to observe the bulge’s stars through the dust, infrared observations are needed. In this study, we will focus on the Color-Magnitude Diagram (CMD) of the bulge’s stars which represent both the number of stars, brightness and colour properties of stars in the area. The observation data from the Vista Variables in the Via Lactea (VVV) are compared with the simulations from the Besan\c{c}on Galactic model in order to the statistic and dynamics of the bulge. The convolution technique and 2D-cross correlation will be applied to the model to fit the data. From the result, the corrected extinction map of the bulge is presented.
