Comments on Properties of Gas Rich Dwarfs Galaxies in the Range of Radio Frequencies (B-Band)

open access: yesIbn Al-Haitham Journal for Pure and Applied Sciences, 2017
    In this project we analyze data of a large sample of gas rich dwarfs galaxies including; Low Surface Brightness Galaxies (LSBGs), Blue Compact Galaxies (BCGs), and dwarfs Irregulars (dIr).

Environmental Quenching of Low-surface-brightness Galaxies Near Hosts from Large Magellanic Cloud to Milky Way Mass Scales

open access: yesThe Astrophysical Journal
Low-surface-brightness galaxies (LSBGs) are excellent probes of quenching and other environmental processes near massive galaxies. We study an extensive sample of LSBGs near massive hosts in the local universe that are distributed across a diverse range ...

Discovery of a Nearby Low Surface Brightness Spiral Galaxy

open access: yesThe Astronomical Journal, 1999
During the course of a search for compact, isolated gas clouds moving with anomalous velocities in or near our own Galaxy (Braun and Burton 1998 A&A, in press), we have discovered, in the data of the Leiden/Dwingeloo survey (Hartmann and Burton 1997, Atlas of Galactic Neutral Hydrogen, CUP) of Galactic hydrogen, the HI signature of a large galaxy ...

On the Origin of Low-Surface-Brightness Galaxies

open access: yes, 1994
We reconsider the problem of the origin of Low-Surface-Brightness (LSB) galaxies within the standard Cold Dark Matter (CDM) cosmological model ($Ω=1, h=0.5$). Taking into account the effect of substructure on the collapse times of low overdensity peaks, we show that the abundance of these peaks is larger than previously expected because of the dragging

Euclid preparation

open access: yesAstronomy & Astrophysics
Local Universe dwarf galaxies can serve as both cosmological and mass assembly probes. Deep surveys have enabled the study of these objects down to the low surface brightness (LSB) regime.

Automatic Search for Low-surface-brightness Galaxies from Sloan Digital Sky Survey Images Using Deep Learning

open access: yesThe Astronomical Journal
Low-surface-brightness (LSB) galaxies play a crucial role in our understanding of galaxy evolution and dark matter cosmology. However, efficiently detecting them in large-scale surveys is challenging, due to their dim appearance.

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

open access: yesThe 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 /

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

open access: yesThe 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.

Tidal Structures Around Edge-On Galaxies in Deep Imaging Surveys

open access: yesGalaxies
We present a statistical study of low-surface-brightness (LSB) tidal structures in two large samples of edge-on disk galaxies. Our primary sample comprises 5606 galaxies from the Edge-on Galaxies In SDSS (EGIS) catalog, analyzed using imaging from the ...

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

open access: yesThe 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 ...
