Book Description
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.

Book Description
Near-infrared astronomy has become one of the most rapidly developing branches in modern astrophysics. Innovative observing techniques, near-infrared detectors with quantum efficiencies in excess of 90%, highly specialised instruments as well as advanced data reduction techniques have allowed major breakthroughs in various areas like exoplanets, star-forming regions, the supermassive black hole in the Galactic center, and the high-redshift Universe. In this book, the reader will be introduced to the basic concepts of how to prepare near-infrared observations with maximized scientific return. Equal weight is given to all aspects of the data reduction for both - imaging and spectroscopy. Information is also provided on the state of the art instrumentation available and planned, on detector technology or the physics of the atmosphere, all of which influence the preparation and execution of observations and data reduction techniques. The beginner but also the expert will find a lot of information in compact form which is otherwise widely dispersed across the internet or other sources.

Book Description
Spectropolarimetry is a remote sensing technique that combines both spectral and polarimetric measurements. It is already well-established in the astronomical community as an indispensable tool, permitting characterization of dust clouds and stars, and enhancing observations of planetary bodies. One such noteworthy phenomenon is the opposition effect, wherein a planetary body such as the Moon exhibits a surge in reflected intensity as the phase angle, an angle between the Sun, the Moon, and the observer, decreases to below approximately five degrees. Astronomical and laboratory investigations into the opposition effect reveal that the light of this surge often has a polarized component. The terrestrial remote sensing community is starting to develop an interest in spectropolarimetry. Spectral and polarimetric measurements alone, while useful in their diverse applications, stand to benefit from the added dimensionality that spectropolarimetric measurements provide. Examples of applications that benefit from spectropolarimetric measurement include environmental monitoring, search & rescue, and countering denial and deception techniques. To that end, an improvised imaging spectropolarimeter sensitive in the visible and near-infrared spectrum has been developed by attaching a linear polarization filter to a SOC700 hyperspectral imaging system for use in further development of spectropolarimetric applications. The results of three research objectives are reported upon. First, validation of the operation of the improvised imaging spectropolarimeter and the resulting data calibration and processing techniques, including generating Stokes parameter imagery, is successfully completed. Second, demonstrating that the improvised system is capable of observing the opposition effect in a laboratory setting is also confirmed. Third, the improvised system is used to characterize various materials, including rare earth element oxides and ultra-high performance concrete, in various phase angle geometries, with the intent of determining whether the polarized component of the opposition effect yields sufficient additional information for material detection and identification.

Book Description
How are large-scale magnetic fields generated in the Sun in self-excited dynamo processes? And how are magnetic structures spontaneously formed in the Sun and how do they interact with the convective flows, storage and release of magnetic energy? These are just several of the fundamental questions answered in this timely review of our understanding of solar magnetic fields. This volume collects together review articles and research papers from an international conference, held in Freiburg, Germany, dedicated to the study of magnetic fields in the Sun. From large-scale patterns and global dynamo action to tiny flux tubes, from the overshoot layer below the convection zone up to the corona, and from instrumental problems and theoretical methods to the latest ground-based and satellite observations, this volume provides an essential review of our knowledge to date for graduate students and researchers.
