X-ray emission from hot gas in spiral galaxies

Y. Terashima, H. Kunieda, K. Makishima, and P.J. Serlemitsos
Abstract

Using ASCA, we observed three nearby spiral galaxies, M104, M51, and M106 and detected X-ray emission from hot gas of temperature kT~0.5 keV from all of them, in addition to the hard emission due to low luminosity active nucleus and discrete sources. From their X-ray images and spectral properties, three possible origins of hot gas are discussed such as starburst activity, heating by AGN jet, and halo in normal spiral galaxies.
