The Dwarf Galaxy Population of the Dorado group down to Mv=-11 [PDF]

, 2000
We present V and I CCD photometry of suspected low-surface brightness dwarf galaxies detected in a survey covering ~2.4 deg^2 around the central region of the Dorado group of galaxies.

Dark Matter Dogma: A Study of 214 Galaxies

Galaxies, 2020
The aim of this paper is to test the need for non-baryonic dark matter in the context of galactic rotation and the apparent difference between distributions of galactic mass and luminosity.

Spectroscopy of Low Surface Brightness Galaxies with the Hobby-Eberly Telescope [PDF]

, 2002
We have obtained low resolution spectra of nineteen red and blue low surface brightness galaxies, using the Marcario Low Resolution Spectrograph on the 9.2m Hobby-Eberly Telescope.

Giant Low Surface Brightness Galaxies

Bulletin de la Société Royale des Sciences de Liège, 2018
In this paper, we present radio observations of the giant low surface brightness (LSB) galaxies made using the Giant Metrewave Radio Telescope (GMRT). LSB galaxies are generally large, dark matter dominated spirals that have low star formation efficiencies and large HI gas disks.

Dwarf and Low Surface Brightness Galaxies [PDF]

Symposium - International Astronomical Union, 1996
The terms ‘dwarf’ and ‘low surface brightness’ are commonly used to mean a variety of different things, and are sometimes used interchangeably. It is thus necessary to explicitly quantify the definitions which are adopted. Here I shall limit the discussion to field galaxies which are [exponential] disks characterized by a scale size h and central ...

The Formation of Disk Galaxies [PDF]

, 1996
We present a scenario for the formation of disks which explains not only the properties of normal galaxies, but the properties of the population of low surface brightness galaxies (LSBs) as well.

Dwarf Galaxies as Low Surface Brightness Galaxies [PDF]

International Astronomical Union Colloquium, 1999
AbstractBecause of the weak correlation between surface brightness and luminosity, as galaxy surveys reach to lower surface brightnesses, increasing numbers of dwarf galaxies are found. Thus, studies of dwarf galaxies are relevant to our understanding of the low surface brightness universe. In particular, studies of nearby LSB dwarfs may help to answer

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 ...

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 ...

Beyond Ultra-diffuse Galaxies. I. Mass–Size Outliers among the Satellites of Milky Way Analogs

The Astrophysical Journal, 2023
Large diffuse galaxies are hard to find, but understanding the environments where they live, their numbers, and ultimately their origins, is of intense interest and importance for galaxy formation and evolution. Using Subaru’s Hyper Suprime-Cam Strategic
