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.A 6-12 GHz analogue lag-correlator for radio interferometry

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.Compact broadband planar orthomode transducer
