The Chemical Evolution of Narrow Emission Line Galaxies: the Key to their Formation Processes The Chemical Evolution of Narrow Emission Line Galaxies: the Key to their Formation Processes

Utilizando la mayor muestra de galaxias con líneas de emisión angostas disponible hasta el momento, se muestra que sus características espectrales están correlacionadas con diferentes parámetros físicos, como las abundancias químicas, las morfologías, las masas del bulbo, y la edad estelar promedio...
