LSB Galaxies and the Tully-Fisher Relation
We present Very Large Array (VLA) Hi imaging of four low surface brightness (LSB) galaxies ([OBC97] P01-3, [OBC97] C06-1, [OBC97] C04-1, [OBC97] C04-2)1 which were thought to strongly deviate from the Tully-Fisher (TF) relation based on Arecibo singledish observations. We do not detect three of the four targeted LSB galaxies in Hi down to a 4σ limit of 0.08Jy km s−1. We find that two of the fou...
متن کاملSurface photometry of bulge dominated low surface brightness galaxies
We present results of broad band BVRI observations of a sample of galaxies with a low surface brightness (LSB) disk and a bulge. These galaxies are well described as exponential disks and exponential bulges with no preferred value for either scale length or central surface brightness. The median B band disk scale length is 12.6 kpc (H0 = 75 km s−1 Mpc−1) which is much larger than scale lengths ...
متن کاملThe 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...
متن کاملSurface photometry of LSB edge-on galaxies
We present results of surface photometry for eleven edge-on galaxies observed with the 6-m telescope at the Special Astrophysical Observatory of the Russian Academy of Sciences. The photometric scale length, the scale height, and the central surface brightness of the stellar disks for the galaxies were found using photometric cuts made parallel to the major and the minor axes for each galaxy. W...
متن کاملThe Chemical Evolution of LSB Galaxies
We have derived oxygen and nitrogen abundances of a sample of late-type, low surface brightness (LSB) galaxies found in the Sloan Digital Sky Survey (SDSS). Furthermore, we have computed a large grid (5000 models) of chemical evolution models (CEMs) testing various time-scales for infall, baryon densities and several power-law initial mass functions (IMFs) as well. Because of the rather stable ...
