We present the OII luminosity function measured in the redshift range
0.1<z<1.65 with unprecedented depth and accuracy. Our measurements are based on
medium resolution flux-calibrated spectra of emission line galaxies with the
FORS2 instrument at VLT and with the SDSS-III/BOSS spectrograph. The FORS2
spectra and the corresponding catalog containing redshifts and line fluxes are
released along with this paper.
In this work we use a novel method to combine the aforementioned surveys with
GAMA, zCOSMOS and VVDS, which have different target selection, producing a
consistent weighting scheme to derive the OII luminosity function.
The measured luminosity function is in good agreement with previous
independent estimates. The comparison with two state-of-the-art semi-analytical
models is very good up to z= 1.1, which is encouraging for the production of
mock catalogs of OII flux limited surveys. We observe the bright end
evolution over 8.5 Gyr: we measure the decrease of log L* from 42.4 erg/s at
redshift 1.44 to 41.2 at redshift 0.165. We find the faint end slope flattening
from alpha(z=0.95)=-2.6 to alpha(z=0.17)=-1.1.
This measurement confirms the feasibility of the target selection of future
baryonic acoustic oscillation surveys aiming at observing OII flux limited
samples.
