The VIMOS Public Extragalactic Redshift Survey (VIPERS). Luminosity and
  stellar mass dependence of galaxy clustering at 0.5<z<1.1
  We investigate the dependence of galaxy clustering on luminosity and stellar
mass in the redshift range 0.5<z<1.1, using the first ~55000 redshifts from the
VIMOS Public Extragalactic Redshift Survey (VIPERS). We measured the
redshift-space two-point correlation functions (2PCF), and the projected
correlation function, in samples covering different ranges of B-band absolute
magnitudes and stellar masses. We considered both threshold and binned galaxy
samples, with median B-band absolute magnitudes -21.6<MB-5log(h)<-19.5 and
median stellar masses 9.8<log(M*[Msun/h^2])<10.7. We assessed the real-space
clustering in the data from the projected correlation function, which we model
as a power law in the range 0.2<r_p[Mpc/h]<20. Finally, we estimated the galaxy
bias as a function of luminosity, stellar mass, and redshift, assuming a flat
LCDM model to derive the dark matter 2PCF. We provide the best-fit parameters
of the power-law model assumed for the real-space 2PCF -- the correlation
length and the slope -- as well as the linear bias parameter, as a function of
the B-band absolute magnitude, stellar mass, and redshift. We confirm and
provide the tightest constraints on the dependence of clustering on luminosity
at 0.5<z<1.1. We prove the complexity of comparing the clustering dependence on
stellar mass from samples that are originally flux-limited and discuss the
possible origin of the observed discrepancies. Overall, our measurements
provide stronger constraints on galaxy formation models, which are now required
to match, in addition to local observations, the clustering evolution measured
by VIPERS galaxies between z=0.5 and z=1.1 for a broad range of luminosities
and stellar masses.
