 Abstract

The ALHAMBRA (Advanced Large Homogeneous Area Medium-Band Red- shift Astronomical) Survey (Molino et al. 2013) is a photometric survey cover- ing 2.8 deg. sq. in 7 independent fields in the sky, to a depth of I(AB)~24.5. It uses a photometric system based on 20 contiguous …

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

macs1206_hst_973

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

XMM_Bullet_Group_625

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 …
