By Sébastien Fabbro (auth.), Domingos Barbosa, António José Da Silva, Ana Maria Mourão (eds.)

The previous couple of years observed the advance of a plethora of experiments and surveys probing the cosmological parameters. The Cosmic Microwave heritage (CMB), the Supernovae (SN) searches and galaxy cluster info, specifically through X-rays and Sunyaev-Zel'dovich impact, are one of the such a lot prolific giving specific information regarding the geometry, age and constitution formation of the Universe.

The software of the WS-HCP workshop was once geared toward highlighting the clinical achievements and to debate the hot setting of "precision cosmology" inside of those 3 probes. the target used to be to examine diversified observational thoughts, universal difficulties particularly foregrounds, and to evaluate the influence of observational uncertainties within the choice of key cosmological parameters which describe the primordial universe and the massive scale constitution formation mechanism.

USSR 9, 341. ARE TYPE Ia SUPERNOVAE STANDARD CANDLES? BRUNO LEIBUNDGUT European Southern Observatory, Karl-Schwarzschild-Strasse 2, D-85748 Garching, Germany Abstract. The use of standard candles for distance measurements is wide spread. Yet, we currently do not know a pure standard candle in astronomy. The concept of standard candles involves not only the secure establishment of a unique luminosity but also a clear observational distinction of the objects as a class. Even Type Ia Supernovae, whose maximum luminosity shows amongst the smallest scatter known, need to be normalised to provide accurate distances.
