The Tolman surface brightness test is one out of a half dozen cosmological test s that was conceived in the 1930s to check the viability of and compare new cosmological model s. Tolman s test compares the surface brightness of galaxy galaxies as a function of their redshift measured as z . Such a comparison was first proposed in 1930 by Richard C. Tolman as a test of whether the universe is expanding universe expanding or static universe static . Different physicists have claimed that the results support different models. Who date March 2009 In a simple static and flat universe, the light received from an object drops inversely with the square of its distance, but the apparent area of the object also drops inversely with the square of the distance, so the surface brightness would be independent of the distance.

First, the rate at which photons are received is reduced because each photon has to travel a little farther than the one before.

A low surface brightness galaxy , or LSB galaxy , is a diffuse galaxy with a surface brightness that, when viewed from Earth , is at least one magnitude lower than the ambient night sky. Most LSBs are dwarf galaxy dwarf galaxies , and most of their baryon ic matter is in the form of neutral gaseous hydrogen, rather than stars. They appear to have over 95 Citation needed date July 2007 of their mass as non baryon ic dark matter . There appears to be no supernova activity in these galaxies. Rotation curve measurements indicate an extremely high mass to light ratio, meaning that stars and luminous gas contribute only very little to the overall mass balance of an LSB. The centers of LSBs show no large overdensities in stars, unlike e.g. the bulge astronomy bulge s of normal spiral galaxies. Therefore they seem to be dark matter dominated even in their centers which makes them excellent laboratories for the study of dark matter. In comparison to the more well studied high surface brightness galaxies, LSBs are mainly isolated field galaxies , found in regions devoid of other galaxies. In their past, they had fewer tidal interactions or mergers with other galaxies, which could have triggered enhanced star formation. This is an explanation for the small stellar content. LSB galaxies were theorized to exist in 1976 by Dr. Michael J. Disney . The first LSB galaxy verified to exist was Malin 1 , discovered in 1986. As such, it was also the first giant LSB galaxy identified. At the time of its discovery, it was the largest spiral galaxy known by scale length measurement . ref name SciAm 1997 02 Scientific American, The Ghostliest Galaxies , GD Bothun , Vol. 276, No. 2, February 1997 , pp.40 ... aps.arxiv.org abs astro ph 0107064 The HI Content and Extent of Low Surface Brightness Galaxies Could ... abs 2004A 26A...422L...5R The environment of Low Surface Brightness Galaxies .

Surface brightness fluctuation SBF is a secondary standard candle distance indicator used to estimate distances to galaxies. The technique uses the fact that galaxies are made up of a finite number of stars. The number of stars in any small patch of the galaxy will vary from point to point, creating a noise like fluctuation in the surface brightness distribution. While the various stars present in a galaxy will cover an enormous range in luminosity, the SBF can be characterized as if all stars had the same brightness, which is the luminosity weighted integral over the luminosity distribution of stars. Older elliptical galaxies have fairly consistent stellar populations, thus the typical fluctuation star closely approximates a standard candle . In practice, corrections are required to account for variations in age or metallicity from galaxy to galaxy. The SBF pattern is measured from the power spectrum of the residuals left behind from a deep galaxy image after a smooth model of the galaxy has been subtracted. The SBF pattern is evident as the transform of the point spread function in the Fourier domain . The amplitude of the spectrum gives the luminosity of the fluctuation star. Because the technique depends on a precise understanding of the image structure of the galaxy, extraneous sources such as globular cluster s and background galaxies must be excluded from the analysis. Areas of interstellar dust absorption must also be excluded. In practice this means that SBF works best for elliptical galaxies or the bulges of S0 galaxy S0 galaxies , as spiral galaxies generally have complex morphologies and extensive dust features. SBF is calibrated by use of fiducial Cepheid Period Luminosity relation P L based on observations of Cepheid variable variables located in the Large Magellanic Cloud .
