Kinematics of Giant Low Surface Brightness Galaxies [PDF]

International Astronomical Union Colloquium, 1999
AbstractHigh sensitivity H I observations now exist for six giant low surface brightness (LSB) disk galaxies including the two prototypes, Malin 1 (Bothun et al. 1987; Impey & Bothun 1989) and F568-6 (also known as Malin 2; Bothun et al. 1990). Their H I surface brightnesses are generally low, but proportionally not as low as their optical surface ...

Structural properties of faint low-surface-brightness galaxies [PDF]

Monthly Notices of the Royal Astronomical Society, 2018
We study the structural properties of Low Surface Brightness galaxies (LSB) using a sample of 263 galaxies observed by the Green Bank Telescope (Schneider et al 1992). We perform 2D decompositions of these galaxies in the SDSS $g$, $r$ and $i$ bands using the GALFIT software. Our decomposition reveals that about $60\%$ of these galaxies are bulgeless i.

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

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.

The stellar populations of low surface brightness galaxies [PDF]

Monthly Notices of the Royal Astronomical Society, 1999
Near-infrared (NIR) K' images of a sample of five low surface brightness disc galaxies (LSBGs) were combined with optical data, with the aim of constraining their star formation histories. Both red and blue LSBGs were imaged to enable comparison of their stellar populations.

The connection between surface brightness and satellite systems for central galaxies through IllustrisTNG

Astronomy & Astrophysics
We analysed different properties of central low-surface-brightness galaxies (LSBGs) and their satellite systems using the simulation TNG100 in order to deepen our understanding of the formation mechanism of LSBGs in a Λ cold dark matter cosmology.

Star formation thresholds in Low Surface Brightness galaxies [PDF]

The Astronomical Journal, 1993
Low Surface Brightness (LSB) galaxies appear to have low star formation rates despite their often quite normal H I contents as judged from global H I properties such as M(H I)/L and M(H I)/M(T) ratios. H I imaging with the Very Large Array of the National Radio Astronomy Observatory (the NRAO is operated by Associated Universities Inc.

Do Low Surface Brightness Galaxies Host Stellar Bars? [PDF]

The Astrophysical Journal, 2017
Abstract With the aim of assessing if low surface brightness galaxies host stellar bars and by studying the dependence of the occurrence of bars as a function of surface brightness, we use the Galaxy Zoo 2 data set to construct a large volume-limited sample of galaxies and then segregate these galaxies as having low or high surface ...
