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 are carrying out a search for Lyα emitting galaxies at z = 6.5 employing slitless spectroscopy at the VLT. In our 43 arcmin field we find three isolated single emission lines with SEDs consistent with line emitting galaxies at z = 6.5.
