Abstract. Interaction of cosmological gamma ray burst radiation with the dense interstellar medium of host galaxy is considered. Gas dynamical motion of interstellar medium driven by gamma ray burst is investigated in 2D approximation for different initial density distributions of host galaxy matter and different total energy of gamma ray burst. The maximum velocity of motion of interstellar me...

nation. Clearly, the universe is not entirely made of molecules and we are exaggerating. In fact, most of the mass in the universe is probably not even made of familiar matter, i.e. the atoms and molecules of which we, the Earth, the solar system, and all the stars in our own and other galaxies are composed. “Dark matter” contains about 90% of the mass of the universe and is detected only by th...

By simple arguments, it is shown how alkaline types of atoms can be seen in dense molecular clouds depending on the average temperature such regions Universe. This paper predicts infrared lines that could clouds. The theory developed first part and predicted experimental results will follow. It modelized using short-range polarization potential are found quantum states n* > 2.

The interstellar medium (ISM) can be thought of as the galactic atmosphere which fills the space between stars. When clouds within the ISM collapse, stars are born. When the stars die, they return their matter to the surrounding gas. Therefore the ISM plays a vital role in galactic evolution. The medium includes starlight, gas, dust, planets , comets, asteroids, fast moving charged particles (c...
