Describing how to investigate all kinds of galaxies through a multifrequency analysis, this text is divided into three different sections. The first describes the data currently available at different frequencies, from X-rays to UV, optical, infrared and radio millimetric and centimetric, while explaining their physical meaning. In the second section, the author explains how these data can be used to determine physical parameters and quantities, such as mass and temperature. The final section is devoted to describing how the derived quantities can be used in a multifrequency analysis to study such physical processes as the star formation cycle and constrain models of galaxy evolution. As a result, observers will be able to interpret galaxies and their structure.
About the Author
Alessandro Boselli is Head of the group Physics of Galaxies at the Laboratoire d'Astrophysique de Marseille, France. He got his academic degree in physics at the Universita di Milano (Italy) and his PhD in astrophysics at the Observatoire de Paris-Meudon (France) under the supervision of J. Lequeux. He then worked at the Max-Planck Institute for Nuclear Physics in Heidelberg (Germany). His research activity is focused on the study of the formation and evolution of galaxies.
