Astronomical Observing Techniques

Vak 2017-2018

Admission requirements

None

Description

This course introduces students to the observational tools of modern astronomy. The course contains lectures and homework on the basics of observational astronomy, provides the theoretical background to understand modern observational techniques and describes the most important techniques and instruments.

The following topics will be covered in lectures and exercises:

  • Properties of radiation (black body, radiometry)
  • Atmospheric properties (transmission, emission, scattering, dispersion)
  • Telescopes (reflector, refractor, mounts, foci, ground/space telescopes)
  • Fourier transform (definition, properties, 1D/2D examples, theorems)
  • Geometrical & diffraction optics (image formation, PSF, aberrations)
  • Measurement properties (signal-to-noise, sensitivities, sampling)
  • Radio techniques (basics, antennae, receivers)
  • Detectors (physical basis, photo-conductors, bolometers, heterodyne)
  • Spectrometers (spectral information, dispersing elements, types)
  • Adaptive optics (principle, components, laser guide stars, types)
  • Interferometry (speckle interferometry, visibility, closure phase)

Course objectives

Students will know and be able to apply the most common techniques that are currently used to observe and understand the universe.

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)
  • Structured thinking (structure, modulated thinking, computational thinking, programming)
  • Responsibility (ownership, self-discipline, bear mistakes, accountability)
  • Motivation (commitment, pro-active attitude, initiative)
  • Self-regulation (independence, self-esteem, aware of own goals, motives and capacities)
  • Flexibility (adaptability, dealing with change, teachability, eagerness to learn)
  • Critical thinking (asking questions, check assumptions)
  • Creative thinking (resourcefulness, curiosity, thinking out of the box)
