Available in PDF, EPUB and Kindle. Book excerpt: We argue that luminous infrared galaxies (LIGs) may constitute a newly detectable population of [gamma]-ray sources for the next generation of ground and space-based high energy telescopes. Additionally, we report for the first time upper limits on their fluxes using data obtained with the EGRET telescope.

Download or read book Strong Evidence for a Buried Active Galactic Nucleus in UGC 5101 Implications for Liner Type Ultraluminous Infrared Galaxies written by and published by . This book was released on 2001 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: We report on the results of 3-4 micrometers spectroscopy of the ultraluminous infrared galaxy (ULIRG) UGC 5101. It has a cool far-infrared color and a LINER-type optical spectrum and so, based on a view gaining some currency, would be regarded as dominated by star formation. However, we find that it has strong 3.4 micrometers carbonaceous dust absorption, low equivalent width 3.3 micrometers polycyclic aromatic hydrocarbon (PAH) emission, and a small 3.3 micrometers PAH to far-infrared luminosity ratio. This favors an alternative scenario, in which an energetically dominant active galactic nucleus (AGN) is present behind obscuring dust. The AGN is plausibly obscured along all lines of sight (a "buried AGN") rather than merely obscured along our particular line of sight. Such buried AGNs have previously been found in thermal infrared studies of the ULIRGs IRAS 08572 3915 and IRAS F00183-7111, both classified optically as LINERs. We argue that buried AGNs can produce LINER-type optical spectra and that at least some fraction of LINER-type ULIRGs are predominantly powered by buried AGNs.

This book was released on 2012-12-06 with total page 524 pages. Available in PDF, EPUB and Kindle. Book excerpt: Progress towards an understanding of the dynamics and interactions of galaxies has been spurred on more than ever by a wealth of new observations and numerical experiments. The Heidelberg Conference 1989, the papers of which are collected in this volume, was extremely successful in presenting a synoptic view of the field in all its aspects: galaxy interactions in the early universe and in recent times, interactions of our galaxy and its neighbours, dynamical problems of elliptical and disk galaxies, groups and clusters, starburst and nuclear activity triggered by interactions, merger scenarios, and numerical experiments. Researchers and graduate students, specialists or not, will find here a complete overview of a rapidly growing field of astronomy.

This book was released on 2013-11-11 with total page 1746 pages. Available in PDF, EPUB and Kindle. Book excerpt: Astronomy and Astrophysics Abstracts is devoted to the recording, summarizing and indexing of astronomical publications throughout the world. Two volumes are scheduled to appear per year. Volume 67 records 10,903 papers covering besides the classical fields of astronomy and astrophysics such matters as space flights related to astronomy, lunar and planetary probes and satellites, meteorites and interplanetary matter, X rays and cosmic rays, quasars and pulsars. The abstracts are classified under more than one hundred subject categories thus permitting quick surveying of the bulk of material published on the same topic within six months. For instance, this volume records 119 papers on minor planets, 155 papers on supernovae, and 554 papers on cosmology.
