XENON 1T Demonstrator Report
Observation suggests ∼80% of all the mass of the universe currently comes from a nonluminous, nonbaryonic form of matter known as dark matter. Currently, WIMPs are one of the most favored models to explain the missing mass of the universe. XENON100, a detector experiment in Gran Sasso, has place the best upper limits for the cross section at ∼ 10−44cm2 for a 50GeV/c mass WIMP. Since detection o...
متن کاملSNLS – the Supernova Legacy Survey
Type Ia supernovae (SNeIa) provide direct evidence for an accelerating universe, and for the existence of " dark energy " driving this expansion. The Supernova Legacy Survey (SNLS) will deliver many hundreds of SNIa detections, and well-sampled g ′ r ′ i ′ z ′ light curves, over the next 5 years. Using these data, we will obtain a precise measurement of the cosmological parameters (Ω mass , Ω Λ...
متن کاملMapping the Dark Energy Equation of State
The acceleration of the expansion of the universe has deep implications for structure formation, the composition of the universe, and its fate. Roughly 70% of the energy density is in a dark energy, whose nature remains unknown. Mapping the expansion history through supernovae, mapping the geometry of the universe and formation of structure through redshift surveys, and mapping the distance to ...
متن کاملProbing Dark Energy with Snap
The distance-redshift relation observed for supernovae has led to the discovery that the expansion of the universe is accelerating. A next generation experiment, the Supernova/Acceleration Probe (SNAP), can investigate the nature of the dark energy responsible, determining its energy density contribution and equation of state. In addition, indications of time variation in the equation of state ...
متن کاملFormation of Large Structures in the Acceleration Universe with a Hybrid Expansion Law
In the current paper, we have studied the effect of dark energy on for-mation where dark energy exists in the background. For this purpose, we used both WMAP9 and Planck data to study how the radius changes with redshift in these mod-els. We used different data sets to fix the cosmological parameters to obtain a solution for a spherical region under collapse. The mechanism of structure formation f...
