The latest research shows that black hole jet flow will affect the Galaxy star forming the first human to capture a supermassive black hole swallows a star moment – the latest research shows that the reduction of animation, the black hole jet flow and heating to disperse large amounts of gas, will hinder the breeding new stars in the galaxy. Tencent news website reported according to space physics, astrophysicist at present, a new study shows that black hole jet flow through the disperse and heating large area gas, can affect the star formation. This is Atta Kama large millimeter and submillimeter wave telescope array (ALMA) based on the neighboring galaxy IC5063 observations. This study combined with the previous IC5063 Galaxy cosmic wind observation data flow diversification jet driven, the supermassive black hole in the center of the galaxy and the cosmic wind is closely related to black hole jet flow driven nearby galaxies forming the various cosmic wind. About 160 million years ago, charged particles (protons) entered the black hole, captured by the magnetic field lines, and ejected at high speed in the form of radio waves. This particle stream travels through the galaxy, more than 3 thousand light-years across. The particle flows through a gas disk, driving a strong cosmic wind at a certain point, causing it to collide with the interstellar nebula. The European Southern Observatory very large telescope observation data show that this cosmic wind for more than 500 thousand years. Scientists ALMA survey data analysis aims to judge whether the cosmic wind gas with different properties than other gas in the nebula, based on this purpose, they focus on the observation from the dense molecular interstellar clouds of carbon monoxide in the injection line, dense interstellar clouds often give birth to new stars, the temperature is minus 263 degrees celsius. They found that the molecular gas is heated by a black hole jet, black hole flow injection temperature reached minus 243 degrees Celsius to 173 degrees Celsius, this effect will hinder the formation of stars, heat and gas vortex gradually increased, delayed gravitational collapse. With the effects of jet flow to remove gas from the dense interstellar Nebula in the nebula, the universe will be dispersed, and lead to the gravitational collapse of a further delay, the quality of the universe in the wind of molecular gas is at least 2 million times the mass of the sun. As the jet stream stores energy, the gas molecules in the cosmic wind will have higher activity than the rest of the interstellar nebula, and the results of this study will encourage scientists to explore further in the field. At the same time, the study shows that the wind will detect molecules than previously thought in distant galaxies in the survey is more simple, only observation of high excited state line to carbon monoxide injection. At present, the latest research report published in the latest edition of the Astrophysical Journal of astronomy, &. (long compile)相关的主题文章:
