Astronomical Observing Techniques

Vak 2019-2020

Please note that this is a preliminary course description. The final version will be released in the Summer of 2019.

Admission requirements

None

Description

This course introduces students to the observational approaches and instruments of modern astronomy. The first part of the course is focused on the theoretical background including Fourier transforms, radiation, the Earth’s atmosphere, and optics. The second part introduces the most important observational techniques including optical and radio telescopes, detectors, spectrometers, and adaptive optics. Students will write their own codes and use optical design software to apply their knowledge.

The lectures and exercises cover the following topics:

  • Properties of radiation
  • Atmospheric properties
  • Fourier transform
  • Geometrical and diffraction optics
  • Telescopes
  • Measurement properties
  • Radio techniques
  • Interferometry
  • Detectors
  • Spectrometers
  • Imagers
  • Adaptive optics

Course objectives

Upon completion of this course, students will be able to select the most appropriate technique to observe a given astronomical phenomena.

In particular, students will be able to:

  • Calculate the properties of radiation received from black bodies
  • Explain the different influences of the Earth’s atmosphere on astronomical observations
  • Perform analytical and numerical Fourier transforms
  • Explain the working principles of optical and radio telescopes
  • Discuss the advantages and disadvantages of different detector types
  • Calculate the expected performance of a given instrument
  • Select an appropriate instrument to observe a given astronomical phenomena

Soft skills

In this course, students will be trained in the following behaviour-oriented skills:

  • Problem solving (recognizing and analyzing problems, solution-oriented thinking)
  • Analytical skills (analytical thinking, abstraction, evidence)
  • Critical thinking (asking questions, check assumptions)
