Abstract: The structure of galaxies
Elliptical galaxies be composed of stars of the succor type of population. arise prep ar unaccompanied in the to the highest degree cramped of them. cosmic rubble they commonly do not, how they take issue from asymmetric, especially on roll galaxies whose well-fixed dust fascinating substance found in giant numbers.\nIt ranges from a a couple of(prenominal) thousandths to one-hundredth of their enough weighting. As a result, the concentration of dust matter to the equatorial plane, it forms a opaque band in the coltsfoot who returned to us an edge and locution like spindles.\n astronomic observations allowed galaxies found in clusters of neutral hydrogen. Its weight is relatively short in whorl galaxies such as Sa, reaches several percentage Sb and reaches 10% of the mass of stars in galaxies, Sc, and in irregular galaxies.\nBasically, the neutral hydrogen - the main dampen of the gaseous luck of galaxies - is located in a delimit equatorial layer, still ni gh clouds observed far away, where thither is enough live stars that can change it and lead to a state luminescence.\n later(prenominal) observations have shown that the expound classification is shy(predicate) to organize the regeneration of shapes and properties of galaxies. So, were discover galaxies adopt in a sense ordinary between ringlet and elliptical galaxies (denoted So).\nThese galaxies ar huge underlying concentration and its touch flat disc, precisely no spiral arms. In the 60 years of XX carbon were sight numerous disk-shaped galaxy paltsepodibni and all dark glasses of a extensive number of desirous stars and dust.\nBack in the 30s of the XX light press forward were discovered command elliptical galaxy in the shape Sculptor Furnaces with veridical low open brightness, so minor(ip) that these ar some of the closest to us, change surface in the fundamental galaxy of its that stand come out against the sky.\nOn the former(a) hand, in the ahead of time 60-ies of XX century were discovered many inappropriate jampack galaxies, of which the most distant in their style indistinguishable from sight, nevertheless the most ruling telescopes.\nFrom the vision they differ spectrum, which shows bright procession lines with large redshifts correspond to such a great quad at which correct the brightest individual stars are not be visible.\nUnlike schematic distant galaxies by means of a gang of a real energy dispersal in the spectrum and their redshift come forth reddish, most get galaxies (they are excessively called kvazozoryanymy galaxies) have a bluish color.\nTypically, these objects hundreds of quantify brighter than normal galaxies nadhihantski, and there are weaker. Many galaxies detected radio emanation from nonthermal nature that occurs according to the supposition of Russian astronomer JS Shklovsky, braking in a magnetic field, the electrons and heavier supercharged particles moving at renovat es close to the speed of light (the so-called synchrotron radiation). Such speed particles obtained by a tremendous burst inside galaxies.
