A method for improving the detection of transient events in the photometric approach of the SuperNova Legacy Survey (SNLS) is presented. The SNLS is a second generation survey with a primary goal of determining the equation of state of dark energy using type Ia supernovae (SNe Ia), based on the Canada-France-Hawaii Telescope (CFHT) which collected data between the years 2003-2008. The approach...

Directional detection is a promising direct Dark Matter (DM) search strategy. The angular distribution of the nuclear recoil tracks from WIMP events should present an anisotropy in galactic coordinates. This strategy requires both a measurement of the recoil energy with a threshold of about 5 keV and 3D recoil tracks down to few millimeters. The MIMAC project, based on a mu-TPC matrix, with...

Le satellite Planck vient de publier, en mars dernier, une mesure des anisotropies du fond diffus cosmologique (CMB) du ciel complet, avec une précision ultime sur une grande gamme d'échelles angulaires.
La large couverture en fréquence, conçu pour fournir une discrimination précise de l'émission galactique des anisotropies primordiales, fait de Planck un outil bien adapté et unique pour...

Clusters of galaxies provide valuable information on the evolution of the Universe and large scale structures. Recent cluster observations via the thermal Sunyaev-Zeldovich (tSZ) effect have proven to be a powerful tool to detect and study them. In this context, high resolution tSZ observations (tens of arcsec) are of particular interest to probe intermediate and high redshift...
