Contribution

It provides a direct comparison between observational data and N-body simulation results for barred galaxies, validating simulation models.

Findings

Good agreement between observed and simulated profiles

Angular momentum exchange influences galaxy evolution

Photometric properties reliably match simulation predictions

Abstract

We compare the results of the photometrical analysis of barred galaxies with those of a similar analysis from N-body simulations. The photometry is for a sample of nine barred galaxies observed in the J and Ks bands with the CANICA near infrared (NIR) camera at the 2.1-m telescope of the Observatorio Astrofisico Guillermo Haro (OAGH) in Cananea, Sonora, Mexico. The comparison includes radial ellipticity profiles and surface brightness (density for the N-body galaxies) profiles along the bar major and minor axes. We find very good agreement, arguing that the exchange of angular momentum within the galaxy plays a determinant role in the evolution of barred galaxies.
