A Survey for Low Surface Brightness Dwarf

By applying a digital ltering technique to 1550 deg 2 of the POSS-II in the vicinity of M31, we found two previously unidentiied very low surface brightness dwarf galaxies which we designate And V and VI. Follow-up imaging with the KPNO 4-m telescope resolved these into stars easily. The V-and I-band images of And V indicate a distance similar to that of M31, and {1.5. All evidence stro...

Does Low Surface Brightness Mean Low Density?

We compare the dynamical properties of two galaxies at identical positions on the Tully-Fisher relation, but with different surface brightnesses. We find that the low surface brightness galaxy UGC 128 has a higher mass-to-light ratio, and yet has lower mass densities than the high surface brightness galaxy NGC 2403. This is true for the gas surface density, the stellar surface density, and the ...

A search for Low Surface Brightness galaxies in the near-infrared I. Selection of the sample

A sample of about 3,800 Low Surface Brightness (LSB) galaxies was selected using the all-sky nearinfrared (J , H and Ks-band) 2MASS survey. The selected objects have a mean central surface brightness within a 5′′ radius around their centre fainter than 18 mag arcsec in the Ks band, making them the lowest surface brightness galaxies detected by 2MASS. A description is given of the relevant prope...

The environment of Low Surface Brightness Galaxies

Using the Early Data Release of the Sloan Digital Sky Survey (SDSS) we investigated the clustering properties of Low Surface Brightness (LSB) galaxies in comparison to normal, High Surface Brightness (HSB) galaxies. We selected LSB galaxies and HSB galaxies with well measured redshifts from the SDSS data base and performed three-dimensional neighbour counting analysis within spheres of radii be...
