In this gallery are many images of Low Surface Brightness Galaxies which have recently been discovered and analyzed. ... The central surface brightness of this galaxy is 24.28 . Malin 2 This galaxy is another huge disk galaxy with a scale length of 15 kpc and a redshift of 15000 km/a. The high surface brightness knot in one of its spiral arms actually has the same color, luminosity and H-alpha equivalent width as the entire Large Magellanic Cloud . ... Truly it is a Low Surface Brightness Galaxy. ...

... 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. ...

... Neutral hydrogen observations of the spiral galaxies NGC 6221 and NGC 6215 with the Australia Telescope Compact Array (ATCA) reveal a wide, two-stranded bridge of at least 3 x 10^8 Msun which can be traced between the two galaxies over a projected distance of 100 kpc. ... The color figure below shows the HI emission (blue) in the bridge velocity range overlaid onto an optical image. ... A tidal HI bridge is visible between NGC 6221 and its brightest neighbour, NGC 6215 (v_sys = 1555 km/s). ...

Observation Strategies . Saturation is a common problem for narrow band filter images of galaxy nuclei. Often the surface brightness of the emission line is estimated from ground-based images with 1" resolution; sometimes line fluxes are quoted for apertures several arcseconds in radius. However, at HST resolution, much of this flux may occur in a single unresolved spot at the galaxy nucleus, thus leading to saturated images. ...

Arecibo Galaxy Environment Survey (AGES) The M74 group is a gas-rich galaxy group located at roughly 10 Mpc and is similar in makeup to the Local Group. M74 dominates the surrounding region and is accompanied by several dwarf galaxies, some of which are star-forming. ... We have decided upon a drift mapping approach to scan the entire region.
