WFSPEC - a multi-object AO instrument for the European extremely large telescope
Optics InfoBase Conference Papers (2007)
Abstract:
WFSPEC is a multi-integral field spectrograph instrument concept combining local AO correction over a wide field of view. This local correction is achieved by a multi object adaptive optics system integrated into the instrument. Instrument concept, development and preliminary results on performance simulations are discussed. © 2007 Optical Society of America.Coevolution of dark matter halos and black holes
ASTR SOC P 379 (2007) 273-275
Abstract:
We investigate a model of the coevolution of black holes and dark matter halos. The evolution of dark matter halos is based on the Press-Schechter theory. Assuming a simple relation between dark matter halos and supermassive black holes enables us to reproduce both the observed evolving hard X-ray luminosity function and the X-ray background.Cosmological behavior of Bekenstein's modified theory of gravity

GaIICS: A hybrid approach to cosmological chemodynamics
EAS PUBLICATIONS 24 (2007) 215-220
Abstract:
This contribution addresses the issue of metal enrichment and the distribution of metals in the lSN/IGM/ICM within the framework of a hybrid N-body plus semi-analytic method. It discusses its impact on galaxy bimodality and multi-wavelength galaxy counts.Magnetized nonlinear thin-shell instability: Numerical studies in two dimensions
