Surface photometry of low surface brightness galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 1995 Low surface brightness (LSB) galaxies are galaxies dominated by an exponential disc whose central surface brightness is much fainter than the value of mu(B)(0) = 21.65 +/- 0.30 mag arcsec(-2) found by Freeman. In this paper we present broadband photometry of a sample of 21 late-type LSB galaxies.

Massive low-surface-brightness galaxies in the eagle simulation [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT We investigate the formation and properties of low surface brightness galaxies (LSBGs) with M* > 109.5 M⊙ in the eagle hydrodynamical cosmological simulation. Galaxy surface brightness depends on a combination of stellar mass surface density and mass-to-light ratio (M/L), such that low surface brightness is strongly ...

H i Observations of Giant Low Surface Brightness Galaxies
The Astrophysical JournalGiant low surface brightness (gLSB) galaxies are galaxies with extremely extended, faint, optical disks over 50 kpc in radius and have high total masses, which can reach 10 ^12 M _⊙ .

LOW SURFACE BRIGHTNESS GALAXIES [PDF]
Annual Review of Astronomy and Astrophysics, 1997 ▪ Abstract The properties of galaxies that are lower in surface brightness than the dark night sky are reviewed. There are substantial selection effects against the discovery of galaxies that are unevolved or diffuse; these systems are missing from most wide field catalogs. Low surface brightness galaxies make up a significant amount of the luminosity

Galaxy formation and evolution: low-surface-brightness galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 1998 We investigate in detail the hypothesis that low surface brightness galaxies (LSB) differ from ordinary galaxies simply because they form in halos with large spin parameters. We compute star formation rates using the Schmidt law, assuming the same gas infall dependence on surface density as used in models of the Milky Way.

Surface Brightness Plateau in S4G Galaxies
Galaxies, 2020 Using 3.6-μm data from 2112 galaxies, we show that, contrary to widely held expectations of a continuous steep decline, radial surface brightness profiles of galaxies tend to flatten and form extended plateaus beyond 27–28 magAB/arcsec2.

Spatial distribution of low-surface-brightness galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 1994 Using redshift samples, we calculate the cross-correlation functions of LSB galaxies with normal galaxies in complete samples (i.e. CfA and IRAS), which enables us to compare directly the amplitudes and shapes of the correlation functions. For pair separations $r\gs 2\mpc$, we find that the shape is in agreement with that of the correlation functions ...

Low Surface Brightness Galaxies and the Field Galaxy Luminosity Function [PDF]
Symposium - International Astronomical Union, 1996 We have developed a catalog of local low surface brightness galaxies (LSBGs) which is selected by objective criteria. We present here a luminosity function (LF) for LSBGs based on that catalog. This LF includes the effects of the completeness corrections to the LSBG catalog, and includes only galaxies with surface brightnesses (22.25 ≤ μB(0) ≤ 24.5 ...

Properties of Nuclear Star Clusters in Low Surface Brightness Galaxies [PDF]
The Astronomical JournalUsing the Systematically Measuring Ultra-Diffuse Galaxies and Sloan Digital Sky Survey catalogs and our own reprocessing of the Legacy Survey imaging, we investigate the properties of nuclear star clusters (NSCs) in galaxies having central surface ...
