| Abstract: |
Diffuse hot gases that are created by supernovae and/or activities of supermassive black hole are key to understand the galaxy evolution, because they blow out from a galactic disk entraining cold interstellar medium and play important roles to regulate star formation and to distribute metals. Such a diffuse hot gas in the Milky Way Galaxy was actually observed with the ROSAT all-sky survey. However, its detailed physical properties have been still under debate. In this talk, I will present the results from our observations of the Galactic diffuse hot gas with Suzaku. We revealed that explosive activities 0.1-10 Myr ago in the Galactic Center produce the large scale hot gas outflows. We also found that supernovae occurred in the Galactic disk likely contribute to the formation of the hot gaseous halo. |
