Spatial distribution of low-surface-brightness galaxies [PDF]

open access: yesMonthly 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]

open access: yesSymposium - 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 ...

A Ghost in Boötes: The Least-Luminous Disrupted Dwarf Galaxy

open access: yesThe Astrophysical Journal, 2022
We report the discovery of Specter, a disrupted ultrafaint dwarf galaxy revealed by the H3 Spectroscopic Survey. We detected this structure via a pair of comoving metal-poor stars at a distance of 12.5 kpc, and further characterized it with Gaia ...

Nearby Gas‐rich Low Surface Brightness Galaxies [PDF]

open access: yesThe 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 ...

Systematically Measuring Ultradiffuse Galaxies (SMUDGes). IV. Ultradiffuse Satellites of Milky Way Analogs

open access: yesThe Astronomical Journal, 2023
To better understand the formation of large, low-surface-brightness galaxies, we measure the correlation function between ultradiffuse galaxy (UDG) candidates and Milky Way analogs (MWAs).

Dwarf Galaxies as Low Surface Brightness Galaxies [PDF]

open access: yesInternational 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

Kinematics of Giant Low Surface Brightness Galaxies [PDF]

open access: yesInternational 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 ...

Understanding the Chemical Evolution of Blue Edge-on Low Surface Brightness Galaxies

open access: yesThe 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.

Searching in H i for Massive Low Surface Brightness Galaxies: Samples from HyperLeda and the UGC

open access: yesThe 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.

Fundamental Properties of the Dark and the Luminous Matter from the Low Surface Brightness Discs

open access: yesUniverse, 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.
