A way out of the dark age in cosmology
spacetime theory aether redshift cosmic expansion first principles
2011/8/4
Abstract: Current doctrines relevant to cosmology are criticized for not being well founded, not being based on definitions and unquestionable first principles alone or violating such principles. This...
Astrophysics and cosmology with galaxy clusters: the WFXT perspective
Astrophysics cosmology galaxy clusters
2011/1/13
We discuss the central role played by the X-ray study of hot baryons within galaxy clusters to reconstruct the assembly of cosmic structures and to trace the past history of star formation and accret...

Real-time Cosmology
2010/11/15
In recent years the possibility of measuring the temporal change of radial and transverse position of sources in the sky in real time have become conceivable thanks to the thoroughly improved techniqu...
In this article we give a brief review of the fundamental physics that can be done with the future space-based gravitational wave detector LISA. This includes detection of gravitational wave bursts co...
The nature of assembly bias - I. Clues from a LCDM cosmology

2010/11/11
We present a new proxy for the overdensity peak height for which the large-scale clustering of haloes of a given mass does not vary significantly with the assembly history.
The Atacama Cosmology Telescope: Cosmology from Galaxy Clusters Detected via the Sunyaev-Zel'dovich Effect
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/24
We present constraints on cosmological parameters based on a sample of Sunyaev-Zel'dovich-selected galaxy clusters detected in a millimeter-wave survey by the Atacama Cosmology Telescope.
Quantum Cosmology Close to the Classical Big Bang Singularity and in the Semiclassical Limit
Quantum Cosmology Semiclassical Limit Big Bang Singularity
2010/3/18
We investigate a cosmological model whose energy content is described by a Chaplygin gas represented by a scalar field $\phi$ with an associated potential producing a big bang singularity such that fo...
