Cosmic motions in the Local Universe
Guilhem Lavaux
Perimeter Institute
A valuable source of information on the distribution of dark matter
and the growth of structures lies in the peculiar velocity field of
the galaxies. After a short review on techniques available for their
determination, I will present the results obtained on two recent techniques
that I developed for estimating the large scale cosmic flows. These two
techniques are based either on dynamical modeling of galaxy redshift
catalog, or the detection of the kinetic Sunyaev-Zel'dovich signal in
the Cosmic Microwave Background. I will show the results obtained when
they are applied on the recent galaxy surveys and WMAP7 sky maps and some
forecasts for PLANCK.
