A single galaxy population? statistical evidence that the Star-Forming Main Sequence might be the tip of the iceberg

P. Corcho-Caballero, Y. Ascasibar, Á. R. López-Sánchez

According to their specific star formation rate (sSFR), galaxies are often divided into `star-forming' and `passive' populations. It is argued that the former define a narrow `Main…
