Kinematics of low surface brightness galaxies [PDF]

, 2008
We analyzed the kinematic of 12 low surface-brightness (LSB) galaxies to study the correlation between the disk circular velocity V_c and the central velocity dispersion of the spheroidal component σ_0. This relation has been claimed to be either the same power-law relation or a different linear one with respect to high surface-brightness (HSB ...

Kinematics of low surface-brightness galaxies [PDF]

, 2007
In order to verify the correlation between the disk circular velocity V_c and the central velocity dispersion of the spheroidal component sigma_c , we analyzed a sample of 12 low surface-brightness galaxies (LSBs). In previous works LSBs have been claimed to follow either a different linear or the same power-law relation with respect to high surface ...

Properties of low Surface Brightness Galaxies

Symposium - International Astronomical Union, 1996
We have been working on multiband surface photometry, spectrophotometry and Hi synthesis data for 20 Low Surface Brightness (LSB) galaxies. LSB galaxies are well described by disks with an average central surface brightness of ∼ 23.4B-mag arcsec–2. They have scale lengths typical for high surface brightness (HSB) galaxies, though a large range of sizes

A Study of 2MASS Low Surface Brightness Galaxies

Astrophysics and Space Science, 2002
A study is being made of a sample of about 4,000 Low Surface Brightness (LSB) galaxies detected in the 2MASS all-sky near-infrared survey. These objects have similar central K-band surface brightnesses as optically selected LSBs. About 1,000 of them were observed in H i, and one third of these were detected.

Blue Low Surface-Brightness Galaxies

1992
The first results from an analysis of CCD photometry of blue low surface-brightness galaxies are presented. The galaxies have a wide range of morphologies, luminosities and ages — all appear to be older than 2 Gyr. We also discuss the results from spectroscopy of ESO 146-G14, a large disk galaxy with low chemical abundances.

Low-Surface-Brightness Galaxies: Hidden Galaxies Revealed

Publications of the Astronomical Society of the Pacific, 1997
In twenty years, low surface brightness (LSB) galaxies have evolved from being an idiosyncratic notion to being one of the major baryonic repositories in the Universe. The story of their discovery and the characterization of their properties is told here. Their recovery from the noise of the night sky background is a strong testament to the severity of

Surveys for Low Surface Brightness Galaxies

1992
In recent years it has become apparent that there exist substantial numbers of Low Surface Brightness Galaxies (LSBGs) in clusters. These were not seen in earlier surveys because of technical limitations and severe selection biases. A group of us at Cardiff (Phillipps, Disney, Davies, Evans) and the APM group at Cambridge (Kibblewhite, Cawson, Irwin ...
