Experimental Astrophysics (eBook, ePUB)

• Format: ePub

Produktbeschreibung

We are now living in the multimessenger era in which often weak and elusive astrophysical phenomena need to be studied using different and orthogonal probes and information carriers in order to be fully understood. Different techniques need to be employed and developed to detect and carefully characterize electromagnetic waves arising from astrophysical objects depending mainly on their energy and other characteristics, such as spectral features and polarization.

This book is designed to give advanced undergraduate students a description of the most popular techniques and instrumentation employed in modern astrophysics. Focusing on electromagnetic radiation and its detection spanning from radio- to X-ray wavelengths, it gives a general description of astrophysical observables, such as flux, brightness, throughput, and magnitude. It describes general concepts about geometrical and physical optics at different wavelengths, in an astronomical context, including the concepts of lenses, mirrors, antennas, telescopes, the focal plane, angular resolution, the field of view, and the diffraction limit. The origin of noise and the extraction of a signal from it is also covered, including noise reduction techniques such as filtering, amplification, as well as cryogenic techniques. The theory of signals and the theorems related to digital electronics are also introduced. A set of student laboratory activities is included to illustrate the concepts covered in the book.

Autorenporträt

Elia Battistelli is an experimental astrophysicist and cosmologist working on several aspects of astrophysics, including the study of the cosmic microwave background (CMB) radiation. Battistelli is currently Associate Professor in the Physics Department of the Sapienza University of Rome, where he teaches the Astrophysics Laboratory course for third-year bachelor physics students and the General Physics course for biotechnology students in the Medicine faculty. In Battistelli's research, he develops radio-frequency, microwave, and millimeter/submillimeter instrumentation for millimeter astronomy and CMB observations and data analysis.
