Galaxy Detection within the RATS project Michael Campbell Zone of Avoidance Our solar system lies about two thirds, or 25,000 light years, away from the galactic centre of the Milky Way. ... The Galaxy Threshold Value After much trial and error it was discovered that the vast majority of object with a star class less than 0.35 were galaxies and the vast majority of objects above 0.35 were stars. I called this the Galaxy Threshold Value. ... Not every object of star class beneath 0.35 is a galaxy. ...

Abstract -- Abundances of heavy elements decreases with increasing galactocentric distance almost in all disk galaxies. ... To explain this gradient in young objects and in the interstellar gas one has to assume that a typical disk galaxy is an open system, i.e. it expels some synthesized heavy elements into the circumgalactic space and/or accretes intergalactic gas with zero metallicity, with rates of both processes depending on the galactocentric distance. ...

The galaxy cluster called MOO J1142+1527 can be seen here as it existed when light left it 8.5 billion years ago. The red galaxies at the center of the image make up the heart of the galaxy cluster. ... In addition to galaxies, clusters also contain a reservoir of hot gas with temperatures in the tens of millions of degrees. CARMA was used to detect this gas and to determine the mass of this cluster. NASA/JPL-Caltech/Gemini/CARMA ...

... According to the most popular cosmological paradigm, the greater part of the galaxy mass is accumulated in the dark matter halo. ... The polar ring galaxies (PRGs) reveal external rings or disks of gas, dust and stars rotating in a plane roughly perpendicular to the disk of the central galaxy. ... The shape of the dark halo in the model was chosen so as to achieve the best fit to the observed rotation of both galaxies themselves and their polar rings. ... The SPRC-7 galaxy. ...

... Research . ... There is mounting evidence that AGN feedback is important in galaxy evolution. Radio-mode feedback is thought to be particularly significant because the mechanical action of the expanding lobes provides a strong coupling mechanism between AGN energy and the surrounding environment. In order to quantify this feedback, detailed models of radio lobe evolution are required. ... Cambridge, UK - Nov 2013 . PDF . Poster for Modern Radio Universe conference . ...

... Our Sun is part of a huge wheel-shaped collection of stars. ... Astronomers have long suspected it was a very massive black hole, and that every galaxy had such a central mass, created early in the history of the universe. ... However, unless that object happens to be headed directly at the black hole (a relatively small target) it will just swing around and fly away again, like a comet making a pass at the Sun. The velocity acquired in falling towards the black hole also helps it escape. ...

... Posts tagged ?host galaxy? ... Without an optical afterglow, a galaxy within the 2 arc second error region of a GRB x-ray afterglow is identified as a host galaxy; however confusion can rise due to the facts that 1. the edge of a galaxy is diffused, 2. multiple sources could exist within 2 arc second error region, 3.the distance between the galaxy and the x-ray afterglow is measured by projection, and 4. lensing causes increase of brightness and position shifts. ...
