Constraining bias and cosmic growth at z=0.6 with the WiggleZ survey   


The use of 2-point statistics (correlation functions and Power spectra) has been the common tool to analyse the galaxy distribution and obtain constraints on cosmological and galaxy formation models. But it does not contain all the information available from the galaxy field, and theoretical understanding combined …

The mass distribution of galaxy clusters: a remarkable agreement between theory and observations


Galaxy clusters are the largest and most recently formed cosmic structures in the universe, of which their content is expected to reflect the overall matter composition. They are dominated by the elusive substance that we call dark matter, but they also contain a smaller fraction of matter in the form of gas and stars. Although only these last components can be directly observed with detectors capable of capturing their electro-magnetic emission covering a broad range of frequencies, from the X-ray …

The nature of dark matter unveiled by cosmic collisions: the bullet group


Dark matter (DM) is one of the pillars of our cosmological understanding yet its nature is still elusive. It makes up about 85% of the Universe’ matter but  its presence has been revealed only through gravity.  The most interesting probes of its presence and nature is the merger of two clusters (or groups) of galaxies. Mergers mix the contents of galaxy groups and clusters, but each component behaves differently. While the  galaxies and DM from both colliding parties take part …
