Abstract

Aims.We investigate the role of the luminous infrared galaxy (LIRG) and ultra-luminous infrared galaxy (ULIRG) phases in the evolution of K_s-selected galaxies and, in particular, Extremely Red Galaxies (ERGs). Methods: .With this aim, we compare the properties of a sample of 2905 K_s1×1011 M&sun; assembled at redshift z=0.5. A minimum of 65% of the galaxies with M>2.5×1011 M&sun; at z ≈ 2{-}3 are ULIRGs at those redshifts. 60% of the ULIRGs in our sample have the characteristic colours of ERGs. Conversely, 40% of the ERGs with stellar mass M>1.3 ×1011 M&sun; at 1.51×1011 M&sun;) galaxies present in the Universe at a given time, this fraction becomes very significant (⪆ 50%) at redshifts z ⪆ 2.
