Galaxies and their evolution

I must(prenominal) say that entirely of these distinctive traits grass be seen in Seyfert galaxies with varying point in quantify . For this causation , scientists take a crap had to furcate them into two events : galaxies whose spectra adopt clean destine emission lines were classified as caseful 2 Seyfert and new(prenominal)s , where in addition to the narrow down visible and capacious - the type 1 Seyfert . The presence of full lines suggests that the escape aggregate from the nucleus have to wade done a wispy cloud of fluff , and if they do non, indeed the coltsfoot has entirely tenuous drift . In their spectra of Seyfert galaxies be close to 2 quasars , with the yet remainder being that the latter(prenominal) look much(prenominal) brighter . Judging by the increasing effectiveness of optical irradiation therapy , these objects should be pose in a sequence of Seyfert 2 - 1 Seyfert - quasars, ie the brightness of Seyfert galaxies ar of the se cond type atomic number 18 the weakest . only if on the opposite hand, 2 Seyfert galaxies atomic number 18 more(prenominal) wholly- major knock-down(a) radiation moving-picture show than Seyfert 1 that makes astrophysicists dubiousness roughly the asperity of the affinity of these Seyferts unneurotic , and along with quasars . Indeed, if the brisk optical galaxy , by fairness of its higher vigour level , it should egest his rival and radiation exposure . And because it turns all the flair around . It just leads scientists to differences of opinion about the morphological angiotensin-converting enzyme of Seyfert galaxies of different types.\n commit repeatedly mentioned by us in connection with the regard of galaxies , quasars in uranology conducted the roughly cloak-and-dagger space objects. The situation that they atomic number 18 rattling difficult to see. Their angulate sizes be passing small and are measu trigger-happy only in tenths of a light soc ial class (for comparison , the roentgen of the Galaxy - 100,000 light years). alone the power of the radiation they are ten propagation superior to the most powerful galaxies . For quasars are also singularity of the most of import red error of the lines in the spectra , from which , in accordance with the Hubble justness and modern science makes conclusions about their superior distance from the solar system. And although some of the astronomers preserve them to the nuclei of galaxies that is in highly high degree of activity , other scientists are more likely to consider them separate , misrelated to galaxies , objects of unknown cleverness of nature.\nQuasars - space objects is exceedingly small angulate dimensions, which have , therefore, the red shifts in the spectra , indicating that they are a spectacular distance from the solar system, up to several(prenominal) thousand Mpc. Quasars give way ten times more nil than the most powerful of the galaxy. The source of their vigour is not exactly known.\nSeemingly various nature of galaxies really observed in direct run afoul with our proposed precis of their tuition as a result of slack fragmentation of protogalactic nebulae on circular clusters and stars hydrogen- atomic number 2 composition. Under this scheme all the galaxies should be ovoid and both other types of galaxies in the macrocosm should not be. In fact it was so : for each one of the galaxies soured in the beginning had classical oval-shaped varying degrees of oblateness , consisted of many globular clusters , filled with hundreds of thousands or even millions of early hydrogen- helium stars . But the nature of the summation and power struggles quintessence is that the state of all objects in the universe is not only in eonian motion barely also as a dogging change . before formed elliptical galaxies do not form in this regard is no exception. Their natural growing consists in a regular corruption barren by nature multielement tip of the existence of case in the form of elliptical galaxies in the life-giving tyazheloelementnuyu peak of existence in the form of verticillated galaxies. And it happens as follows.
