The GOYA Survey addresses four main science questions

1- Characterize the Low-Mass Star-Forming Galaxies at intermediate redshifts (0.7<z<1.7):

SFR tracers: Hα, [OII]; Metallicity: [OIII+OII]/Hβ, [NII]/Hα; Extinction: Hα/Hβ; Kinematics & Virial Mass: velocity widths

2- To explore the formation and evolution of the most massive galaxies at high redshift (1<z<3):

IMF diagnostic; Ages/metallicities: 4000-break, Hβ, Mg2, Fe; Kinematics & Virial Masses :sigma; Scaling Laws: empirical relations between structural and kinematics, stellar population parameters

3- Discover and study primeval galaxies at z>5:

Detection of Lyα and HeII 1640 in the NIR

4- Constrain cosmological parameters:

ΩM and ΩΛ: L(Hβ)-sigma distance indicator; Fine structure constant: [OIII]5007 & [OIII]4959
