García-Dabó L. Domínguez-Palmero Física, Astronomía y Matemáticas In this work we present merger fractionsfrom galaxy samples selected by either Ks-luminosity, or B-band luminosity, from theGOYA photometric survey of the Grothstrip using asymmetry indices to identifymerging galaxies. The merger fractio n inB-band can be approximated by the func-tion Fmg(z) = 0:006(1 + z)3:2. The mergerfraction in Ks-band has a minimum at z =0.6 and is slightly higher in more massivegalaxies. 2007 artículo científico 0185-1101 https://www.redalyc.org/articulo.oa?id=57102972 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.29 |
