Algorry Física, Astronomía y Matemáticas Galaxies formation evolution — galaxies We present results about the formation and evolution of stel lar bars in Milky-Way sized galaxies using the EAGLE Λ CDM cosmological hydrodynamical simulation. In agreement wit h observational results, this simu- lation shows that ∼ 40% of our simulated disk galaxies have a stellar bar with a wi de variety of bar strengths. Typical bar lengths are ∼ 6 . 5 kpc also comparing favourably to observed ones. Our unbarred di sks are more gas-rich and star-forming than those having a strong bar. In concordance with previous work, bars develop in galaxies where the disk is gravitationally dominant over th e dark matter halo. 2017 artículo científico 0185-1101 https://www.redalyc.org/articulo.oa?id=57153211073 en http://www.redalyc.org/revista.oa?id=571 Revista Mexicana de Astronomía y Astrofísica application/pdf Universidad Nacional Autónoma de México Revista Mexicana de Astronomía y Astrofísica (México) Vol.49 |
