Quantifying the Bimodal Color-magnitude Distribution of Galaxies
We analyse the bivariate distribution, in color versus absolute magnitude (u − r vs. Mr), of a low redshift sample of galaxies from the Sloan Digital Sky Survey (SDSS; 2400deg, 0.004 < z < 0.08, −23.5 < Mr < −15.5). We trace the bimodality of the distribution from luminous to faint galaxies by fitting double-Gaussians to the color functions separated in absolute magnitude bins. Color-magnitude ...
متن کاملAre star formation rates of galaxies bimodal?
Star formation rate (SFR) distributions of galaxies are often assumed to be bimodal with modes corresponding to star-forming and quiescent galaxies, respectively. Both classes of galaxies are typically studied separately, and SFR distributions of star-forming galaxies are commonly modelled as lognormals. Using both observational data and results from numerical simulations, I argue that this div...
متن کاملPdf bimodal distribution
Unimodal distribution or a clearly bimodal distribution, depending on the means. The upper limit of the probability density axis in the PDF plot is adjusted by.family of distributions generated by fixing H Φ and letting g be any symmetric pdf. More generally, there has been a number of works exploring bimodality.
متن کاملThe bimodal spiral galaxy surface brightness distribution
We have assessed the significance of Tully & Verheijen’s (1997) bimodal Ursa Major Cluster spiral galaxy near-infrared surface brightness distribution, focussing on whether this bimodality is simply an artifact of small number statistics. A KolmogorovSmirnov style of significance test shows that the total distribution is fairly represented by a single-peaked distribution, but that their isolate...
متن کاملThe Case against Bimodal Star Formation in Elliptical Galaxies
We consider the present-day photometric and chemical properties of elliptical galaxies, adopting the bimodal star formation scenario of Elbaz, Arnaud & Vangioni-Flam (1995). These models utilise an initial mass function (IMF) biased heavily toward massive stars during the early phases of galactic evolution, leading to early Type II supernovae-driven galactic winds. A subsequent lengthy, milder,...
