- BSc course on Astronomical Observing Techniques;
- Basic knowledge of solid state physics.
Part ‘a’ of this course is aimed at observational astronomers in general, to provide a solid knowledge basis about the generation of their data.
Detectors are the crucial link between the astronomical target and the observer. Apart from the telescope, their performance is arguably the single most important component – and often weakest link – in the chain of observational components. As astronomers are aiming at fainter and fainter targets, the quality and calibration of the detector systems have become increasingly important. Detector types that will be discussed include intrinsic and extrinsic photo-conductors, CCDs, BIB detectors, photodiodes, bolometers, and submillimeter- and millimeterwave heterodyne receivers. The course covers their physical principles and discusses performance aspects like linearity and dynamical range, spectral response, bandwidth, quantum efficiency and noise. In addition, this course covers practical aspects which are of general relevance to observational astronomers, such as readout schemes, cosmetic quality of array detectors, and the mitigation of artefacts.
The main objectives of this course are to provide an overview of:
- the various technologies (and underlying physics) used to detect electromagnetic radiation from UV to sub-millimeter wavelengths;
- the most common devices to be found in astronomical instruments;
The students will not only understand how detector work but also learn about performance aspects, mitigation of artefacts, and calibration strategies, which are relevant to the data analysis.

Mode of instruction
Lectures and weekly homework assignments.
The assessment is mainly done by a written exam at the end of the course (part ‘A’). The exam is “closed book”, a formula sheet will be provided. The exam consists of three parts: calculations (~50%), qualitative explanations (~30%), and multiple choice questions (~20%).
In addition, there are weekly homework assignments. These are mandatory.
The final grade is determined from the written exam (80%) and the homeworks (20%)
Given the relatively small number of students and the good rate of success, the re-take exam will be an oral exam.
No. Lecture notes, homeworks, additional readings and assignments will be provided on the course website (see below).
