1. Low Surface Brightness Galaxy Gallery
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. ...

2. Measurement of the dark halo shape in polar ring galaxies
... 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. ...

3. Examples and Photometric Tests
Next: Implementation Up: Image Restorations of High Previous: Technique . This method has been tested on many kinds of data both real and simulated. Here we present three examples in which the structure of the background is of increasing interest and photometry of point sources of diminishing importance. ... Fig. 1 shows the results of this and Fig. 2 shows the photometric accuracy and also a histogram of the background image. ... Fig. 4 shows the quality of the resulting photometry. ...

5. HIPASS Results and Lessons
... HIPASS results . ... Of the BGC galaxies, 138 have redshifts for the first time. ... We really need ALFA to address that faint end. ... This estimate accounts for the smaller beam size, the number of pixels, and the available solid angle. ... HIPASS (with an integration time of 250 sec per pixel) was complete only for M * galaxies at cz ALFA (with the same intergration time) would be complete to 15,000 km/s . ... The integration time would be only 1 sec per beam for a total time of about 2.6 hours. ...

6. GSAOI Dwarf Galaxies Science Page
... GSAOI Home . ... Science . ... For example, among the Milky Way's dE companions we see systems with dominant old populations, systems with minor intermediate-age (age ~ 2 to 10 Gyr) components, and systems where the intermediate-age component dominates the old stars. ... This variety of star formation histories is not restricted to the Galaxy's companions. ... To make progress in understanding the processes that govern dwarf galaxy evolution, we need to study systems beyond the Local Group. ...
