IV WORKSHOOP ON THE DARK SIDE OF THE UNIVERSE The value of Ec is determined by the particle physics model and constraint by the dark matter properties derived from cosmology.

IV WORKSHOOP ON THE DARK SIDE OF THE UNIVERSE From gauge group dynamics we expect the mass of the confined particles is of the order of the transition energy e.g. proton m = 938 with  QCD = 200 MeV, c = 4.6 MOTIVATION BOUND DARK MATTER

9 The BDM particles behaves as Radiation Above the energy scale Ec. e.g HDM Matter Below the energy scale Ec e.g CDM We could find this behaviour in two situations: 1.At the beginin of the Univers. THE MODEL AT THE BEGINNING OF THE UNIVERSE JORGE MASTACHE / 12-06-12IV WORKSHOOP ON THE DARK SIDE OF THE UNIVERSE BDM Matter Radiation

10 We could find this behaviour in two situations: 1.At the beginin of the Univers. THE MODEL AT THE BEGINNING OF THE UNIVERSE Since the particles of BDM travel at the speed of light at energy densities above ρc there will be a cut at small scales in the power spectrum and BDM will erase inhomogeneities and inhibit structure formation for scales below the free streaming scale λfs ΛCDM predicts an overpopulation of satellite galaxies around our own galaxy.

11 2. Inside of the galaxies. THE MODEL INSIDE OF GALAXIES HDMCDM BDM predicts a core in galaxies. As long as ρg < ρc we expect a standard CDM galaxy profile, which may be given by the NFW profile. A great number of rotation curves in dwarf and LSB galaxies fits better considering a dark matter halo with a core profiles than a cuspy profile.

27 MORE WORK Anisotropies on the CMB

28 MORE WORK BAO

29 Instituto de Astronomía 2011 The model predict a core of 0.23 - 2.3 kpc in the halo dark matter in galaxies. The BDM profile fits better (or equally well) than NFW profile. We end up with a profile with one fundamental constant from the theory, and two free parameters given by the morphology of the galaxies. The lower limit of the energy transition is constrained at Ec = O(0.1) eV by the LSB rotation curve. The higher limit is given by the large scale structure formation Ec = O(100) eV. We expect a BDM transition between this two limit values. The BDM model have shown strenghts in several cosmological observations (BAO, CMB, RC) but we still have work to do in order to verify its true nature.
