In this thesis, we study supersymmetric extensions of the Standard Model and particularly the phenomenological implications arising from discrete and flavor symmetries. Symmetries are frequently added to theories in order to simplify the treatment and to reach phenomenologically viable regions of the parameter space.At the beginning of the disserta...
High pressure xenon gas detectors have the potential to significantly contribute to searches for rare physics processes such as neutrinoless double beta (0νββ) decay and interactions of dark matter with ordinary matter. We summarize the physics and implications of these two phenomena and discuss experimental developments conducted with an electrolu...
We present profiles of temperature, gas mass, and hydrostatic mass estimated from new and archival X-ray observations ofCLASHclusters. We comparemeasurements derived fromXMMand Chandra observations with one another and compare both to gravitational lensing mass profiles derived with CLASH Hubble Space Telescope and Subaru Telescope lensing data. Ra...
We report on the X-ray observation of a strong lensing selected group, SL2S J08544-0121, with a total mass of 2.4±0.6×1014 M⊙ which revealed a separation of 124±20 kpc between the X-ray emitting collisional gas and the collisionless galaxies and dark matter (DM), traced by strong lensing. This source allows to put an order of magnitude estimate to ...

In N-body simulations of cold dark matter, it has been found that three-parameter models, particularly the Einasto profile, yield better fits to a wide range of dark matter haloes than two parameter models like the Navarro-Frenk-White profile. Recently, the analytical properties of the Einasto profile has been studied, allowing closed expressions f...

We use the observed anisotropic clustering of galaxies in the Baryon Oscillation Spectroscopic Survey Data Release 11 CMASS sample to measure the linear growth rate of structure, the Hubble expansion rate and the comoving distance scale. Our sample covers 8498 deg2 and encloses an effective volume of 6 Gpc3 at an effective redshift of z̄ = 0.57. We...
