This book serves as both a primer to astronomical polarimetry and an authoritative overview of its application to various types of astronomical objects from AGN, compact stars, binary systems, stars across the HR diagram, transients, the interstellar medium and solar system bodies. It starts with an historical perspective, a discussion of polarimetric theory, instrumentation and techniques in wave bands from the near infrared to gamma rays. The book presents the state of the art in astronomical polarimetry. It is motivated by the new X-ray polarimeters due to be launched in the next four years and improved optical polarimeters on large telescopes requiring a new analysis of polarimetric theory, methodology and results.This book will be suitable as advanced undergraduate companion text, a primer for graduate students and all researchers with an interest in astronomical polarimetry.

At this conference, both particle physicists and cosmologists presented exciting new results, from experiments that determine with unprecedented accuracy whether the universe is spatially flat, whether it is accelerating and what the nature of the dark matter could be, to more speculative ideas about its origin, based on theories of particle physics which might be confirmed or disproved in the not too distant future. This conference convinced everyone that we are truly living in the Golden Age of Cosmology.
John "Black Jock" Glimer (ca. 1799- ca 1870) was born in Ireland. He married Isabella "Belle" Cochrane sometime in 1818. They had eight children. In ca. 1832 they emigrated to Lower Canada. Their son, John Gilmer (1819-1911) was born in Ballyclare, Ireland. He married Mary Jane Christie in 1839 and they settled in Pleasant Valley, Upper Canada. They had at least ten children. John and Isabella's son, Alexander (1821-1896) and his wife, Jane Lyness of Belfast settled in Clinton County, Iowa and later moved to Winsted, Minnesota. Descendants live throughout the United States. Includes information on the families of Gilmer, McCalla and Workman.
This monograph includes a wide range of Gareth McConnell's work from 1995 to the present. Beginning with the series Anti-Social Behaviour, looking at people who have endured punishment beatings in Northern Ireland, it includes Boxers, a series of portraits from a boxing club in Bournemouth as well as Portraits from Ibiza.
The Reuven Ramaty High Energy Solar Spectroscopic Imager (RHESSI) satellite was launched on 5 February 2002. Its objective is to study the energy release and particle acceleration in solar flares through observations of X-rays and gamma rays. Two novel technologies are combined to obtain both spectra and images over a broad energy range. For the spectroscopy, cooled hyperpure germanium detectors are used to cover the energy range from 3 keV to 17 MeV with unprecedented keV-class resolution. Since focusing optics are not possible for making images with such high energy photons, tungsten and molybdenum absorbing grids are used to modulate the X-rays and gamma-rays coming from the Sun as the sp...
