| contents | Galaxy Formation Simulations with Scalar Field Dark Matter T. Matos G. Torres Física, Astronomía y Matemáticas DARK MATTER GALAXIES: HALOS GALAXIES: EVOLUTION GALAX IES: FORMATION We present simulations of galaxy formation using a scalar field cosmologicalmodel in which the dark matter is modeled by scalar field . In the Scalar FieldDark Matter (SFDM) model the dark matter consists of an ultra-light particle, withmass m 10_23 eV. Since in the SFDM model all the successes of the standardcold dark matter model are recovered, this suggests that the scalar field could bea good candidate for the dark matter in galaxy halos. In this work, we performsimulations for the formation of the luminous part of galaxies using the SFDMmodel, supposing that a dark matter fluctuation forms and evolves, attracting theluminous matter around it. Under these conditions, we find that the luminousmatter evolves and forms objects with spiral arms, and later evolves into an objectwith circular symmetry, looking very similar to the observed spiral galaxies. 2003 artículo científico 0185-1101 https://www.redalyc.org/articulo.oa?id=57139110 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) Num.1 Vol.39 |
