... We consider the astrophysical evolution of the Galaxy over large time scales, from early stages (an age of ~10 8 yrs) to the end of traditional stellar evolution (~10 11 yrs). ... In the model considered, the basic stages of Galactic evolution are as follows. ... Essentially all other basic parameters of the Galaxy vary little. ... The final "stellar epoch" in the life of the Galaxy is completed ~10 13 yrs after its formation, when the evolution of the least massive stars comes to an end. ...

... ROTATION CURVE: When studying spiral galaxies it is invariably found that the stellar rotational velocity in the disk remains constant, or "flat", with increasing distance away from the galactic center. ... The rotation speed of the stars in galaxies is found NOT to decrease with increasing distance from the galactic center (see emission lines in the spectrum), implying that the overall mass distribution of the galaxy is different from the light distribution. ...

The divisity of galaxies. The galaxies are the giant (to hundred of billions of stars) star systems, where the stars are connected by gravitation laws with each other. ... Ther galaxy NGC 3031 . ... Each spiral galaxy has a core a flat disk where the spiral brancher locate. The stars and interstellar substance of spiral galaxies rotate around the core. ... In normal galaxies, such as our Galaxy, the great brightness of the core is accounted for the high concentration of stars. ...

... Sternberg Astronomical Institute , Moscow University . ... Present edition unites two parts of Catalogue of interacting galaxies by B.A.Vorontsov-Velyaminov: the first part (Part 1) containing 355 systems was published in 1959 [1] and the second one (Part 2) with 497 objects - in 1976 [2].Thus two published parts of Catalogue include 852 interacting systems. ... All new of them (1162 by number) were taken from the comments to the galaxies in Morphological catalogue by Vorontsov-Velyaminov et al.[ ...

... Bad Astronomy . ... Bitesize Astronomy . ... Last week's Snack talked about how black holes can affect the environment around them in such a way as to be very bright . ... It's a common misconception that black holes always have matter swirling into them. ... As this matter gets closer and closer to the black hole it piles up and a large, fairly flat disk forms. This is called the accretion disk , because matter from this disk accretes (that is, falls in) on the black hole. ... 2008 Phil Plait. ...

... The circumnuclear GASEOUS disks are often decoupled from the circumnuclear stellar disks and are even stronger inclined to the outer disk planes; in fact, we have found a considerable `population' of inner polar rings. Inner gas polar rings are found as in spiral galaxies with the massive outer gas disks co-planar to the main symmetry planes (e.g. NGC 2841, Sil'chenko et al. 1997, and NGC 7217, Sil'chenko & Afanasiev 2000) as well in many lenticular galaxies (Fig. ...

ATMoB "Galaxy Observing Award " Guidelines Purpose: To promote observing among the membership of the Amateur Telescope Makers of Boston through participation in the Galaxy Observing Awards program. ... Examples of elliptical galaxies: M49, M59, M60, M87, NGC 4125. Limiting Magnitude Assessment: Spirals: A spiral galaxy consists of a flattened disk, with stars forming a (usually two-armed) spiral structure, and a central concentration of stars known as the bulge. ...

Next: Critical Frequencies and Gravitational Previous: Extragalactic Gravitational Wave Background . The number of binaries per frequency decade per solid angle from a separate stellar system (galaxy or cluster of galaxies) is . ... For example, for the Andromeda galaxy M31 ( rad, ) one gets . ... If the angular size of the galaxy is less than the angular resolution of the detector, the critical frequency is independent of the angular resolution, . ...

... Previous: Substepping and its Application to HST Imaging . ... This is a preliminary report on an application of the co-addition technique based upon the Richardson-Lucy algorithm. The combination of high signal-to-noise ground-based images obtained with the ESO NTT using SUSI with high angular resolution HST FOC f/96 images gives new insights on the properties of galaxy cores and their potential time variability. Cores of galaxies are one of the main thrusts of present extragalactic research. ...

... The color composite image of Centaurus A reveals the lobes and jets emanating from the active galaxy?s central black hole. ... Astronomers have a new insight into the active galaxy Centaurus A (NGC 5128), as the jets and lobes emanating from the central black hole have been imaged at submillimetre wavelengths for the first time. ... Centaurus A hosts a very active and highly luminous central region, caused by the presence of a supermassive black hole is the source of strong radio and X-ray emission....

... We present preliminary results from two programs to image the host galaxies of radio-quiet quasars in 1.6 micron light using NICMOS camera 2 on HST. The high redshift program consists of QSOs covering the redshift range 0.8 < z < 4.4 and a range of QSO luminosities. Of the six objects for which data have been obtained the results range from no host galaxy detected, to an obvious galaxy with an interacting companion, to a possible high redshift galaxy cluster. ...
