Cosmic Masers - From Oh to H0 (Iau S287) - Colloqui

Klappentext Cosmic masers, naturally occurring amplifiers of microwave emission from atoms and molecules in the Milky Way and other galaxies, provide important tools to investigate astrophysical environments. The first, hydroxyl (OH) masers were discovered in 1965 and since that time several thousand sources of maser emission, from a variety of cosmic molecules, have been discovered and studied. Because this natural emission occurs at discrete frequencies, which depend upon specific atomic or molecular transitions, masers are also useful for studying the structure and dynamics of our own galaxy. Masers in other galaxies are now used for cosmological studies of the dynamics of massive black holes in galactic nuclei and to directly measure the Hubble constant, H0. This volume contains a comprehensive, up-to-date review of cosmic masers, their nature, sources, environments and uses, as presented at IAU Symposium 287, the fourth international symposium on cosmic masers. 'These proceedings show a vital community that is looking to the future and present an outstanding set of scientific advances ...' The Observatory: A Review of Astronomy Zusammenfassung Cosmic masers provide important tools to investigate galactic structure and environments. This volume contains the latest research on masers! as presented at IAU Symposium 287! providing a comprehensive and up-to-date review of their nature! sources! environments and uses.
