... This paper describes the capabilities of GIM2D, an IRAF package for the quantitative morphology analysis of distant galaxies. GIM2D automatically decomposes all the objects on an input image as the sum of a S?rsic profile and an exponential profile. ... GIM2D (Galaxy IMage 2D) is an IRAF package written to perform detailed bulge/disk decompositions of low signal-to-noise images of distant galaxies. ... The segmentation image is used by GIM2D to deblend galaxy images. ... Create a residual image. ...

Multiple Supernovae in the same galaxy . ... When looking at these images, you should note just how big these galaxies are. ... SN 2009as and sn2009gb images sub-page . ... LOTOSS discovered 2003hl , and a few weeks later JM Llapasset was taking an image of it, and he noticed a new star . ... Supernovae 2002cv and 2002bo in NGC 3190 2002cv was discovered by Campo Imperatore Observatory while observing 2002bo in IR. 2002cv was only visible in IR must likly due to it being behind a dust lane. ...

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. ...

... Astronomy news . ... NASA's Spitzer Images Out-of-This-World Galaxy . ... It is spiral-shaped like our Milky Way, with long, spindly arms of stars. The "eye" at the center of the galaxy is actually a monstrous black hole surrounded by a ring of stars. In this color-coded infrared view from Spitzer, the area around the invisible black hole is blue and the ring of stars, white. ... The ring around the black hole is bursting with new star formation. ...

... Take the air we breathe: its molecules have energies around 0.03 ev (electron volt--see energetic particles ) as fast as a cannonball, though still quite a bit slower than the typical satellite. ... The Sun's plasma is much hotter , and that of the magnetosphere is still hotter. ... They are known as cosmic rays or cosmic radiation . ... Actually, the source of cosmic rays is probably not quite as intense, because cosmic ray particles can stay around the galaxy much longer than starlight. ...

. F IGURE . 6. Metallicities of the RR Lyrae stars as a function of apogalactic distance (a,b,c) and maximum distance from the Galactic plane (d,e,f). The straight lines are least-squares fits.The five most distant stars in each panel (in boxes) were excluded from our calculations. The correlation coefients and their uncertainties are indicated. discussion in the text | privious figure .
