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

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.

Enhanced cobweb clustering for identifying analog galaxies in astrophysics

2014 IEEE 27th Canadian Conference on Electrical and Computer Engineering (CCECE), 2014
Clustering, a very popular task in Data Mining, is unsupervised classification of patterns (observations, data items, or feature vectors) into groups (clusters). Clustering has been explored in many different contexts and disciplines. In this paper, we explore using the COBWEB clustering algorithm to identify and group together galaxies whose spectral ...

Cosmology and astrophysics with galaxy clusters

AIP Conference Proceedings, 2014
Galaxy clusters are the largest gravitationally bound objects in the universe, whose formation is driven by dark energy and dark matter. The majority of the baryonic mass in clusters resides in the hot X-ray emitting plasma, which also leaves imprints in the cosmic microwave background radiation.
