Alonso, O. ; Zamorano Calvo, Jaime ; Rego Fernández, Manuel ; Gallego Maestro, Jesús ; Vitores, A.G. | Kluwer Academic Publ. | 1994The most unambiguous way to discover new emission-line galaxies (ELGs) is directly by the presence of their lines, using objective-prism plates of adequate resolution. The first survey using this technique was developed by Smith in 1975 with the[...]texto impreso
Evolutionary population synthesis models with different metallicities have been computed in order to interpret the observed Mg_2 and H?, line-strength indices in old stellar populations. Both indices are found to be quite insensitive to change[...]texto impreso
