Scientific paper

In this work we present merger fractions from galaxy samples selected by either Ks-luminosity, or B-band luminosity, from the GOYA photometric survey of the Groth strip using asymmetry indices to identify merging galaxies. The merger fraction in B-band can be approximated by the function F_{mg}(z) = 0.006(1 + z)^{3.2}. The merger fraction in Ks-band has a minimum at z = 0.6 and is slightly higher in more massive galaxies.
