Relating bars with the environment in the nearby Universe

TL;DR

This study investigates how the presence of bars in spiral galaxies correlates with environmental factors, finding that the fraction of barred galaxies remains largely unaffected by different environments.

Contribution

It applies a specific technique to analyze a large galaxy sample, confirming that bar fraction is nearly environment-independent, adding robustness to previous findings.

Findings

Bar fraction is almost insensitive to environment

Supports previous results on bar-environment relationship

Uses a large, well-defined galaxy sample

Abstract

We study the correlation between the fraction of barred spiral galaxies and environmental parameters of galaxies to understand in which environments the bars are more commonly found. For this purpose we apply the Blanton et al. technique to a sample of spiral galaxies drawn from the Nair & Abraham catalogue. Our results agree with previous findings in which the fraction of barred galaxies is almost insensitive to environment.
