Spectra of quasars and gamma-ray bursts - the brightest objects in the universe - carry a lot of information about these heavenly "lanterns". Astronomers from the University of California at Santa Cruz, studying these spectra, came to an interesting conclusion that in the direction of the gamma-ray burst is 4 times more galaxies than to quasars. This ratio can not be due to the different nature of quasars and gamma-ray bursts, so intrigued scientists are trying to find an explanation for this strange phenomenon of space. Quasars (quasi-stellar objects) were first discovered coleslaw salaatti in 1960. Scientists have noticed the stars, which were identified coleslaw salaatti with strong radio sources. Analysis of the spectra of these stars showed that they are at a distance, measured in billions of light-years. With further their study it was found that it was not a star, and the core of distant galaxies at the stage of unusually high activity. Radiation power exceeds the power quasars Sun a trillion times, but this is due to the absorption of the substance black holes at the centers of distant galaxies. Gamma-ray bursts (gamma ray burst, GRB), or gamma explosions of a different nature. They are formed coleslaw salaatti in the conversion of massive stars, coleslaw salaatti neutron stars and black holes are the most powerful explosions in the universe.
Scientists do not see any connection between these two objects of different nature, has not yet concluded the strange relationship between them. The results coleslaw salaatti of a new study conducted by means of the telescope at the William Keck (WM Keck), and data from space observatory "Swift (Swift), said that before each of the 4 randomly selected gamma-ray bursts are likely to be one galaxy, whereas when observing four different coleslaw salaatti galaxy quasar would be only to one of them. This result can not be explained, more than that - contrary to the basic concepts of cosmology.
Of course, with some degree of probability could have been expected coleslaw salaatti that the galaxies may rarely appear coleslaw salaatti in front of distant space objects, but at the same time to manifest coleslaw salaatti regularity with respect to quasars and gamma-ray bursts - such was not expecting anyone. But observational data - are stubborn things, and spectral analysis - the best way to prove the obvious.
When light from a GRB or quasar passes through the galaxy, located on the line of sight, the absorption of certain wavelengths of light gas available in the galaxy produces a characteristic signature in the spectrum of a distant coleslaw salaatti object. It also gives out presence of the galaxy before the object, even if the galaxy itself is too weak to observe it directly.
Analyzing so fifteen GRB, fixed space telescope "Swift", the researchers found in their spectrum characteristic absorption lines, indicating the presence of galaxies to 14 gamma-ray bursts. coleslaw salaatti To determine the number of galaxies along the line of the observer-quasar, astronomers used data from the Sloan Digital Sky Survey (Sloan Digital Sky Survey, SDSS). Analysis of the spectra of quasars 50,000 gave the average number of "overshadow" galaxies, equal to 3.8, against a 14-gamma-ray bursts.
To date, scientists suggest three possible explanations for this strange divergence. coleslaw salaatti The first states that some quasars are completely obscured galaxies with a large amount of dust. And if we do not see all the quasars, it makes an error in the results of research. But in this respect there is a counter-argument is that with a huge database of quasars, this effect would be identified, accounted for and minimized.
Another explanation is that the absorption lines of the gas GRB appear ejaculated by the GRB, rather than from a gas consisting of galaxies. However, almost every observation, when examined in detail astronomers space towards GRB, they found galaxy in the place where it was to be in the absorbing gas.
The third idea is to show the galaxy as a gravitational lens, increasing the brightness of the object, and this effect has on gamma-ray bursts completely different effect than on emission coleslaw salaatti of quasars. Such an explanation is considered
