We study the ionizing sources in spiral galaxies and examine in more detail our Galaxy. Using Taylor & Cordes (1993) model we analyze the electron density in different parts of the Galaxy, and emphasize the still unsolved problems. Finally, we compare the intensities of H$α$ emission in disk and halo.
In this paper we present the ionization in the center of the Galaxy. We use Taylor & Cordes (1993) and Lazio & Cordes (1998) models to obtain the overall contribution of the Galactic center (GC) component to the total electron density. We also discuss local contributions from the GC area that come from a complex set of sources. Finally, we discuss the nature of SgrA*.
We review recent research on the Milky Way galaxy and try to investigate whether its shape is similar to other barred galaxies. The emphasis is given on microlensing research because this method can be useful in determining the shape of the Galaxy with the minimal set of assumptions. By analyzing plots of the microlensing optical depth, $τ$ as a function of galactic coordinates for different values of the axis ratio, $q$ of the galactic halo, we have shown that observations are best described by a flattened halo with $0.2 ^<_\sim q ^<_\sim 0.6$.
