Nearby Gas‐rich Low Surface Brightness Galaxies [PDF]
The Astrophysical Journal, 2000 We examine the Fisher-Tully cz<1000 km/s galaxy sample to determine whether it is a complete and representative sample of all galaxy types, including low surface brightness populations, as has been recently claimed. We find that the sample is progressively more incomplete for galaxies with (1) smaller physical diameters at a fixed isophote and (2 ...

Searching in H i for Massive Low Surface Brightness Galaxies: Samples from HyperLeda and the UGC
The Astronomical Journal, 2023 A search has been made for 21 cm H i line emission in a total of 350 unique galaxies from two samples whose optical properties indicate they may be massive.

Understanding the Chemical Evolution of Blue Edge-on Low Surface Brightness Galaxies
The Astrophysical Journal, 2023 We present a sample of 330 blue edge-on low surface brightness galaxies (ELSBGs). To understand the chemical evolution of ELSBGs, we derived the gas-phase abundance and the [ α /Fe] ratio.

Fundamental Properties of the Dark and the Luminous Matter from the Low Surface Brightness Discs
Universe, 2021 Dark matter (DM) is one of the biggest mystery in the Universe. In this review, we start reporting the evidences for this elusive component and discussing about the proposed particle candidates and scenarios for such phenomenon.

Low-surface-brightness Galaxies are Missing in the Observed Stellar Mass Function
The Astrophysical Journal, 2023 We investigate the impact of the surface-brightness (SB) limit on the galaxy stellar mass functions (GSMFs) using galaxy catalogs generated from the Horizon Run 5 ( HR5 ) simulation.

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

PEARLS: Low Stellar Density Galaxies in the El Gordo Cluster Observed with JWST
The Astrophysical Journal, 2023 A full understanding of how unusually large ultradiffuse galaxies (UDGs) fit into our conventional theory of galaxy formation remains elusive, despite the large number of objects identified locally.

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 ...
