CCD calibration.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. This book is designed to give advanced undergraduate students a description of the most popular techniques and instrumentation employed in modern astrophysics.University students in physics, astronomy and engineering.Also available in print.Mode of access: World Wide Web.System requirements: Adobe Acrobat Reader, EPUB reader, or Kindle reader.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.Title from PDF title page (viewed on November 8, 2021).
