NIKA: a mm camera for Sunyaev-Zel'dovich science in clusters of galaxies
  Clusters of galaxies, the largest bound objects in the Universe, constitute a
cosmological probe of choice, which is sensitive to both dark matter and dark
energy. Within this framework, the Sunyaev-Zel'dovich (SZ) effect has opened a
new window for the detection of clusters of galaxies and for the
characterization of their physical properties such as mass, pressure and
temperature. NIKA, a KID-based dual band camera installed at the IRAM 30-m
telescope, was particularly well adapted in terms of frequency, angular
resolution, field-of-view and sensitivity, for the mapping of the thermal and
kinetic SZ effect in high-redshift clusters. In this paper, we present the NIKA
cluster sample and a review of the main results obtained via the measurement of
the SZ effect on those clusters: reconstruction of the cluster radial pressure
profile, mass, temperature and velocity.
