Constraining Dark Matter candidates from structure formation
We show that collisional damping of adiabatic primordial fluctuations yields constraints on the possible range of mass and interaction rates of Dark Matter particles. Our analysis relies on a general classification of Dark Matter candidates, that we establish independently of any specific particle theory or model. From a relation between the collisional damping scale and the Dark Matter interac...
متن کاملConstraining the Dark Matter Distribution With Large-Scale Structure Observations
We discuss the use of galaxies to trace the large-scale structure of the universe and thereby to make cosmological inferences. We put special emphasis on our lack of knowledge about the relative distribution of galaxies and the dynamically important dark matter. We end with a discussion of the increasing importance of infrared astronomy to large-scale structure studies.
متن کاملConstraining the strength of Dark Matter Interactions from Structure Formation
We discuss the damping of primordial dark matter fluctuations, taking into account explicitly the interactions of dark matter – whatever their intensity – both with itself and with other particle species. Relying on a general classification of dark matter particle candidates, our analysis provides, from structure formation, a new set of constraints on the dark matter particle mass and interacti...
متن کاملDark Matter: the Connection with Gamma-Ray Astrophysics Discovering Dark Matter particles with astrophysical observations
We review the status of indirect Dark Matter searches, focusing in particular on the connection with gamma-ray Astrophysics, and on the prospects for detection with the upcoming space telescope GLAST and Air Cherenkov Telescopes such as CANGAROO, HESS, MAGIC and VERITAS. After a brief introduction where we review the fundamental motivations for indirect searches, we tackle the question of wheth...
متن کاملPossible astrophysical clues of dark matter
The supernova physics may provide a clue of the cosmological dark matter. In the absence of new physics, the supernova calculations do not explain the observed velocities of pulsars. However, if there exists a singlet fermion with mass in the 1–20 keV range and a small mixing with neutrinos, this particle could be emitted asymmetrically from a cooling neutron star in the event of a supernova ex...
