The Core-Cusp Problem

Advances in Astronomy, 2010
This paper gives an overview of the attempts to determine the distribution of dark matter in low surface brightness disk and gas-rich dwarf galaxies, both through observations and computer simulations.

Comparing Galaxies and Lyman Alpha Absorbers at Low Redshift

, 1997
A scenario is explored in which Lyman alpha absorbers at low redshift arise from lines of sight through extended galaxy disks, including those of dwarf and low surface brightness galaxies.

Galaxy clustering as a function of surface brightness [PDF]

, 1985
Using diameters and magnitudes of galaxies listed in the Nilson catalog, the angular correlation properties of highand low-surface brightness galaxies are examined.

Structure and dynamics of galaxies with a low surface-brightness disc - II. Stellar populations of bulges

, 2012
The radial profiles of the Hb, Mg, and Fe line-strength indices are presented for a sample of eight spiral galaxies with a low surface-brightness stellar disc and a bulge.

The Intracluster Light of Abell 3667: Unveiling an Optical Bridge in LSST Precursor Data

The Astrophysical Journal Letters
Intracluster light (ICL), the diffuse glow of stars stripped from galaxies during a cluster’s formation, is an established tracer of a cluster’s dynamical history. The upcoming Vera C.

LIGHTS. Survey Overview and a Search for Low Surface Brightness Satellite Galaxies

The Astronomical Journal
We present an overview of the LBT Imaging of Galactic Halos and Tidal Structures survey, which currently includes 25 nearby galaxies that are on average ∼1 mag fainter than the Milky Way, and a catalog of 54 low central surface brightness (24 < μ _0, _g /

Oxygen abundances in low surface brightness disk galaxies

The Astrophysical Journal, 1994
The oxygen abundances in the \HII regions of a sample of low surface brightness (LSB) disk galaxies are presented. In general, LSB galaxies are found to be metal poor ($Z < {1 \over 3} Z\solar$). Indeed, some LSB galaxies rival the lowest abundance extragalactic objects known. These low metallicities indicate that LSB galaxies evolve slowly, forming

Finding Massive Double-exponential Disk Galaxies with Extended Low Surface Brightness Stellar Disk: An IllustrisTNG Exploration

The Astrophysical Journal
We study massive disk galaxies (stellar mass > = 10 ^11 M _⊙ ) at z = 0 from IllustrisTNG simulation to detect galaxies that contain two exponential stellar disks—a central high surface brightness (HSB) disk surrounded by an extended low surface ...

Searching for ultra-diffuse galaxies in the Dark Energy Survey using an object-detection algorithm

Astronomy & Astrophysics
Ultra-diffuse galaxies (UDGs) are a class of galaxies characterized by an extremely low surface brightness and large effective radius. The significance of UDGs lies in their unique properties, such as their diverse dark-matter content, which collectively

Massive low surface brightness galaxies [PDF]

A multi-wavelength study of an extreme type of galaxy which will assist us in our attempts to understand the formation and evolution of galaxies was completed. In particular, a subset of low surface brightness (bar-mu(sub B) is approximately greater than
