A surface brightness correction to the Formula relation

VI.B-band Tully-Fisher relation and mean surface brightness

Continuing our study of the type dependence of the TF relation, we present a new attempt to reduce the scatter of that relation by using the observed mean surface brightness Σ of galaxies. It is shown that the zero-point of the relation is a continuous function of Σ, well described by a third or fourth degree polynome. Taking this effect into account, the TF scatter decreases by 20 percents, an...

A Haar wavelets approach to Stirling's formula

This paper presents a proof of Stirling's formula using Haar wavelets and some properties of Hilbert space, such as Parseval's identity. The present paper shows a connection between Haar wavelets and certain sequences.

from linguistics to literature: a linguistic approach to the study of linguistic deviations in the turkish divan of shahriar

chapter i provides an overview of structural linguistics and touches upon the saussurean dichotomies with the final goal of exploring their relevance to the stylistic studies of literature. to provide evidence for the singificance of the study, chapter ii deals with the controversial issue of linguistics and literature, and presents opposing views which, at the same time, have been central to t...

Low Surface Brightness Galaxies

The Influence of Galaxy Surface Brightness on the Mass–metallicity Relation

We study the effect of surface brightness on the mass–metallicity relation using nearby galaxies whose gas content and metallicity profiles are available. Previous studies using fiber spectra indicated that lower surface brightness galaxies have systematically lower metallicities for their stellar mass, but the results were uncertain because of aperture effects. With stellar masses and surface ...
