Supermassive black hole collision 10 million years a steady glow glow.

<P> Keywords: supermassive black hole black hole collisions </ P> <P> a new study, the use of existing astronomical equipment to observe the collision of supermassive black holes formed after the last "Infrared sunset", which can continue sunset .light 10 years. .This study helps scientists discover early signs of black hole collisions. .</ P> <P align=center> </ P> <P> Milky Way black hole found in the first 2 run around the supermassive black hole (Figure) </ P> <P> scientists found that the black hole </ P> <P> universe .Ten stars in a mystery </ P> <P> supermassive black hole mass of the sun for millions to several billions of times, often they appear in galaxies like the Milky Way or larger center. .Collisions like this are the most violent phenomena in the universe, black holes collision energy produced far beyond the energy of the universe and all the stars. .Formed by the collision energy is generally considered to form the release of gravitational waves, the formation of galaxies in space elusive ripples, these devices can be detected by astronomical observations. .</ P> <P> colliding particles </ P> <P> Johns Hopkins University 杰里米施尼特曼 (Jeremy Schnittman) and Zhu 利安克罗利 grams (Julian Krolik) latest calculation .shows the infrared glow black hole collisions sustainable release of 10 of years. .This continued from the bright aura called "accretion disks (accretion discs)" in the thick dust and gas cloud in accretion disks around black holes, provision of supplies to the black hole. .World Scientific reports </ P> <P> according to the latest results, when two black holes collide, space, matter accretion disks orbit will be disturbed, resulting in another collision between particles. .Shiniteman told the "New Scientist" magazine: "After the collision of gas particles in the new circular orbit stabilized, the gas particles by other particles will jump up and collision in the collision of gas particles had lost a lot of energy .. "The energy is converted into X-rays and other forms of light, before they will eventually form the infrared gas in the accretion disk of dust maze bounce beat. .</ P> <P> only release IR </ P> <P> researchers said NASA, "Spitzer," Space Telescope, equipped with an infrared capability to detect, can be observed in infrared light show such beautiful sunset scene. .Shiniteman said, "is different from other infrared sources in space, the collision of black holes just will not give X-ray or ultraviolet light, we only need to find the infrared source is." Not involved in the research astrophysicist at Columbia University, Kerry.斯坦蒙诺尤 (Kristen Menou) said this is a very attractive astronomy. .World Scientific reports </ P> <P> Shiniteman and Croatia Lick is estimated that there are supermassive black holes and cosmic collision of more than 100,000 infrared sources can be observed. .They "Astrophysical Journal" presented in this study. .</ P> <P> one day astronomers will detect the collision of supermassive black holes by the gravitational waves emitted, because of this very low frequency gravity waves, the current laser interferometer gravitational wave observatory (LIGO) could not detect the existence of gravity waves .. .One called "Laser Interferometer Space Antenna (LISA)" space mission plan may detect gravitational waves generated by a black hole collisions, but the space program will be launched in 2018. .</ P> </ p>.
