نویسنده
چکیده
Various cosmological applications of galaxy clusters are presented. Clusters are used to determine the baryon fraction, dark matter distribution and the matter density Ωm of the universe. They also contain a wealth of information about structure formation and evolution on different scales: large-scale structure, cluster formation and also galaxy formation via the interaction of cluster galaxies with the intra-cluster medium. In particular, the X-ray satellites CHANDRA and XMM yield exciting new results for galaxy cluster physics and cosmology.

We present a review of the follow-up observations carried out from observatories located in Spain; Calar-Alto, Izaña and Roque de Los Muchachos. It summarizes the observations carried out by our group for 27 GRBs occurred in the period 19992000, spanning from GRB990123 to GRB001007.

Preliminary results are presented from the CLEF hydrodynamics simulation, a large (N = 2 × 428 3 particles within a 200 h −1 Mpc comoving box) simulation of the ΛCDM cosmology that includes both radiative cooling and a simple model for galac-tic feedback. Specifically, we focus on the X-ray properties of the simulated clusters at z = 0 and demonstrate a reasonable level of agreement between sim...

We discuss two main aspects of the GRB 000301C afterglow [1,2]; its short duration and its possible connection with a Damped Lyα Absorber (DLA). GRB 000301C falls in the short class of bursts, though it is consistent with belonging to the proposed intermediate class or the extreme short end of the distribution of long-duration GRBs. Based on two VLT spectra we estimate the H I column density to...

The observed infall of galaxies into the Virgo Cluster puts strong constraints on the mass of the cluster. A non-parametric fully non-linear description of the infall can be made with orbit reconstructions based on Numerical Action Methods. The mass of the cluster is determined to be 1.2 × 10M⊙. The mass-to-light ratio for the cluster is found to be seven times higher than the mean ratio found ...

I show that advanced simulations of cosmological reionization are able to fit the observed data on the mean transmitted flux in the hydrogen Lyman-alpha line at z ∼ 6. At the same time, posteriori models can be constructed that also produce a large value (20%) for the Thompson scattering optical depth, consistent with the WMAP measurements. Thus, it appears that a consistent picture emerges in ...
