The Multifrequency Astrophysics of Galaxy Clusters

Chinese Journal of Astronomy and Astrophysics, 2003
We discuss the evidence and the physical relevance of the astrophysical phenomena (of thermal and non-thermal origin) occurring in galaxy clusters as obtained from multi-frequency observations, from radio to gamma-rays.

The Molecular Astrophysics of Stars and Galaxies

1998
Abstract This book provides a comprehensive survey of modern molecular astrophysics. It includes an introduction to molecular spectroscopy and then addresses the main areas of current molecular astrophysics, including galaxy formation, star forming regions, mass loss from young as well as highly evolved stars and supernovae, starburst ...

Detailed astrophysical properties of Lyman Break Galaxies

2003
A large statistical sample of z~3 galaxies has been efficiently UV-color-selected, and confirmed spectroscopically. Here we present additional observations providing insight into the physical conditions in these Lyman Break Galaxies (LBGs), selected to be rapidly forming stars when the universe was ~15% of its current age.

Cosmology and Astrophysics with Clusters of Galaxies (Invited)

2004
I discuss the role that X-ray galaxy clusters plays in the determination of cosmological parameter. In particular I focus the discussion on the evolution of the cluster mass function for the determination of the density parameter Ωm and the normalization of the power spectrum σ8. Available constraints indicate that Ωm lies in the range 0.2–0.5, with σ8

Astrophysics in the Next Decade: The Evolution of Galaxies

2009
One of the primary goals of observational cosmology is to understand how galaxies form and evolve into the current population of objects we observe around us today. The redshift range, 1.5 ⩽ z ⩽ 3.5 represents a crucial epoch for observing the assembly of the modern galaxy population, which is largely in place by z ∼ 1.

Systematics and astrophysics: towards an evolutionary classification of galaxies?

2002
It is possible to borrow from a topic of biology called phylogenetic systematics, concepts and tools for a logical and objective classification of galaxies. It is based on observable properties of objects - characters - either qualitative (like morphology) or quantitative (like luminosity, mass or spectrum).
