Most hard X-ray selected quasars in Chandra Deep Fields are obscured
J. X. Wang, P. Jiang, Z. Y. Zheng +13
Measuring the population of obscured quasars is one of the key issues to understand the evolution of active galactic nuclei (AGNs). With a redshift completeness of 99%, the X-ray s…
VADER - A Satellite Mission Concept For High Precision Dark Energy Studies
Rene Fassbender, Jutta Stegmaier, Anne-Marie Weijmans +8
We present a satellite mission concept to measure the dark energy equation of state parameter w with percent-level precision. The Very Ambitious Dark Energy Research satellite (VAD…
Magellan Spectroscopy of AGN Candidates in the COSMOS Field
Jonathan R. Trump, Chris D. Impey, Patrick J. McCarthy +8
We present spectroscopic redshifts for the first 466 X-ray and radio-selected AGN targets in the 2 deg^2 COSMOS field. Spectra were obtained with the IMACS instrument on the Magell…
DEMON: a Proposal for a Satellite-Borne Experiment to study Dark Matter and Dark Energy
Alicia Berciano Alba, Pedro Borges da Silva, Hans Eichelberger +12
We outline a novel satellite mission concept, DEMON, aimed at advancing our comprehension of both dark matter and dark energy, taking full advantage of two complementary methods: w…
