On the Ionizing Sources in Spiral Galaxies: I. From Central Regions to Thick Disk and Disk-Halo Connection
Abstract
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 Hα emission in disk and halo.
