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.
The idea behind this volume is an excellent one - to give budding astronomers or astrophysicists some understanding of many of the widgets they and their colleagues will be using to collect data. The focus is on electromagnetic radiation. [...] I turned eagerly to sections on devices I would really like to understand better - Zener versus Schottky diodes, lock-in amplifiers, Johnson noise, field-effect transistors (and with hopes for integral field units, but they are apparently not here - no index; though a quite detailed table of contents). Not, frankly, a lot of joy. A possible interesting use for the text would be to assign to individual students individual sections to be amplified, clarified, perhaps updated, and I would be happy to review the expanded, modified volume!
