How luminous galaxies trace dark Universe

dr hab. Agnieszka Pollo, prof. NCBJ

I plan to present the most recent results of the VIMOS Public Extragalactic Redshift Survey (VIPERS). VIPERS - with its \sim 90,000 spectroscopically measured galaxies in an unprecedentedly large volume (5 x 10^7 h^(-3) Mpc^3), and an effective spectroscopic sampling > 40% - can be considered the state-of-the-art counterpart of "local" (z<0.2) cosmological surveys but targeting the epoch at z \sim 1. How different were galaxies 8 bln years ago in comparison to their descendants we find in our local Universe? What are the properties of the 3D cosmic structure emerging from VIPERS measurements? What can they tell us about the properties and history of the cosmic stricture woven from dark matter and even more elusive dark energy? What do they add to our understanding of the evolution of the Universe and galaxies themselves? In my seminar, I try to answer some of these questions - and show new challenges emerging from these new results.
