This course introduces students to the observational tools of modern astronomy. The first part concerns the basics of observational astronomy, the second part concerns the theoretical background of observational techniques, and the third part describes specific 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)
Students will know and be able to apply the most common techniques that are currently used to observe and understand the universe.
