## 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 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)

## Timetable

## Assessment method

Written exam (100%), see Examination schedules bachelor Astronomy.

Homework assignments (up to 1 bonus grade point if all homework has been done independently and submitted on time)

## Blackboard

Blackboard will be used to communicate with students and to share lecture slides, homework assignments, and any extra materials. You must enroll on Blackboard before the first lecture. To have access, you need a student ULCN account.
