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.

A Morphological-type dependence in the mu_0-log(h) plane of Spiral galaxy disks [PDF]

, 2001
We present observational evidence for a galaxy `Type' dependence to the location of a spiral galaxy's disk parameters in the mu_0-log(h) (central disk surface-brightness - disk scale-length) plane.

Surface Brightness Plateau in S4G Galaxies

Galaxies, 2020
Using 3.6-μm data from 2112 galaxies, we show that, contrary to widely held expectations of a continuous steep decline, radial surface brightness profiles of galaxies tend to flatten and form extended plateaus beyond 27–28 magAB/arcsec2.

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.

Normal Globular Cluster Systems in Massive Low Surface Brightness Galaxies [PDF]

, 2007
We present the results of a study of the globular cluster systems of 6 massive spiral galaxies, originally cataloged as low surface brightness galaxies but here shown to span a wide range of central surface brightness values, including two intermediate ...

The dark and baryonic matter content of low surface brightness disk galaxies [PDF]

, 1997
We present mass models of a sample of 19 low surface brightness (LSB) galaxies and compare the properties of their constituent mass components with those of a sample of high surface brightness (HSB) galaxies.We find that LSB galaxies are dark matter ...

Evidence for a Non-Expanding Universe: Surface Brightness Data From HUDF [PDF]

, 2005
Surface brightness data can distinguish between a Friedman-Robertson-Walker expanding universe and a non-expanding universe. For surface brightness measured in AB magnitudes per angular area, all FRW models, regardless of cosmological parameters, predict

Surface photometry of low surface brightness galaxies [PDF]

Monthly Notices of the Royal Astronomical Society, 1995
Low surface brightness (LSB) galaxies are galaxies dominated by an exponential disc whose central surface brightness is much fainter than the value of mu(B)(0) = 21.65 +/- 0.30 mag arcsec(-2) found by Freeman. In this paper we present broadband photometry of a sample of 21 late-type LSB galaxies.

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.
