Evi- GHz methanol masers in OMC-1, for which there is reason. In this volume the full range of astrophysical maser research is covered, with contributions from many of the foremost researchers in the field. The topics include Download book PDF. Chapters PDF · Astronomical Maser Radiation PDF · The Environments of Astronomical Masers. Moshe Elitzur. Pages 216-231. PDF.
In addition, aspects of light via particle and wave theory are reviewed. Special relativity, photoelectric effect and radiation in quantum mechanics are the studied topics in the modern era.
The Astrophysical Virtual Observatory initiative (AVO) was a project to create the foun- dations of a European scale infrastructure by conducting a research and demonstration programme on the Virtual Observatory (VO) scientific requirements… This review will present an overview of maser polarization observations and magnetic field determinations of the last several years and discuss the implications of the magnetic field measurements for several important fields of study, such… Read chapter 4 Report of the Panel on Planetary Systems and Star Formation: Every 10 years the National Research Council releases a survey of astronomy an Credit: K. Steffen, S. V. Nghiem, R. Huff, and G. Neumann. Its composition began to be revealed with the discovery of OH masers (1612 MHz) in 1968. H 2O, SiO, CO, HCN, CS, SO, SO 2, and H 2S molecules have also been detected. The intention was to stiffen the structures using angular momentum, eliminating the need for struts, and saving mass. In all cases, surprisingly large amounts of tensile strength were needed to cope with dynamic loads. Megamasers are distinguished from astrophysical masers by their large isotropic luminosity. Megamasers have typical luminosities of 103 solar luminosities (L), which is 100 million times brighter than masers in the Milky Way, hence the…

Generally, radio and microwave masers can be produced more easily (gyrosynchrotron emission, curvature radiation) than those at shorter wavelengths , although there are suggestions for astrophysical lasers even in the X-ray regime… Finally, the radiation from astrophysical masers can be quite weak and may escape detection due to the limited sensitivity (and relative remoteness) of astronomical observatories and due to the sometimes overwhelming spectral absorption… Because of this dredge-up, AGB stars may show S-process elements in their spectra and strong dredge-ups can lead to the formation of carbon stars. •OH masers, a type of astrophysical maser, were the first masers to be discovered in space and have been observed in more environments than any other type of maser.

Main subjects of research are AGNs and star forming regions by using masers as probes. From 2010, an effort to extend the VLBI network to the East Asia in cooperation with China and Korea has been made.
