Dark Matter, Dark Energy, and Fundamental Physics
More than sixty years ago Zwicky made the case that the great clusters of galaxies are held together by the gravitational force of unseen (dark) matter. Today, the case is stronger and more precise: Dark, nonbaryonic matter accounts for 30%±7% of the critical mass density, with baryons (most of which are dark) contributing only 4.5% ± 0.5% of the critical density. The large-scale structure that...
متن کاملIndirect searches for SUSY Dark Matter with the MAGIC Cherenkov Telescope
Neutralinos are the natural well-motivated candidates to provide the non-baryonic dark matter of the universe which may produce detectable signals through their annihilation into neutrinos, photons or positrons. Due to its high flux sensitivity and low energy threshold, the MAGIC Cherenkov telescope could potentially detect the neutralino annihilation high energy photon products. In the framewo...
متن کاملThe Dark Matter Telescope
Weak gravitational lensing enables direct reconstruction of dark matter maps over cosmologically significant volumes. This research is currently telescopelimited. The Dark Matter Telescope (DMT) is a proposed 8.4 m telescope with a 3◦ field of view, with an etendue of 260 m deg, ten times greater than any other current or planned telescope. With its large etendue and dedicated observational mod...
متن کاملSearches for dark matter subhaloes with wide-field Cherenkov telescope surveys
The presence of substructures in dark matter haloes is an unavoidable consequence of the cold dark matter paradigm. Indirect signals from these objects have been extensively searched for with cosmic rays and � rays. At first sight, Cherenkov telescopes seem not very well suited for such searches, due to their small fields of view and the random nature of the possible dark matter substructure po...
متن کاملTowards an optimized design for the Cherenkov Telescope Array
The Cherenkov Telescope Array (CTA) is a future instrument for very-high-energy (VHE) gamma-ray astronomy that is expected to deliver an order of magnitude improvement in sensitivity over existing instruments. In order to meet the physics goals of CTA in a cost-effective way, Monte Carlo simulations of the telescope array are used in its design. Specifically, we simulate large arrays comprising...
