Formation of Hot Intergalactic Gas by Gas Ejection from a Galaxy in an Early Explosive Era Formation of Hot Intergalactic Gas by Gas Ejection from a Galaxy in an Early Explosive Era 池内, 了 IKEUCHI, Satoru metadata only access © 2014 The Physical Society of Japan Chemical evolution of a galaxy in an early explosive era is studied by means of one zone model. Calculating the thermal properties of interstellar gas and the overlapping factor of expanding supernova-remnant shells, the gas escape conditions from a galaxy are examined. From these, it is shown that the total mass of ejected gas from a galaxy amounts to 10∼40 % of the initial mass of a galaxy. The ejected gas extends to the intergalactic space and the whole universe. The mass, the heavy-element abundance and other physical properties of thus formed intergalactic gas are investigated for various parameters of galactic evolution. Some other effects of gas release on the evolution of a galaxy and the evolution of the universe are discussed.
