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

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

Schedule

You will find the timetables for all courses and degree programmes of Leiden University in the tool MyTimetable (login). Any teaching activities that you have successfully registered for in MyStudyMap will automatically be displayed in MyTimeTable. Any timetables that you add manually, will be saved and automatically displayed the next time you sign in.

MyTimetable allows you to integrate your timetable with your calendar apps such as Outlook, Google Calendar, Apple Calendar and other calendar apps on your smartphone. Any timetable changes will be automatically synced with your calendar. If you wish, you can also receive an email notification of the change. You can turn notifications on in ‘Settings’ (after login).

Registration

As a student, you are responsible for registering on time, i.e. 14 days before the start of the course. This can be done via Mystudymap. You do this twice a year: once for the courses you want to take in semester 1 and once for the courses you want to take in semester 2. Please note: late registration is not possible.

Registration for courses in the first semester is possible from July; registration for courses in the second semester is possible from December. First-year bachelor students are registered for semester 1 by the faculty student administration; they do not have to do this themselves. For more information, see this page

In addition, it is mandatory for all students, including first-year bachelor students, to register for exams. This can be done up to and including 10 calendar days prior to the exam or up to five calendar days in case of a retake exam. You cannot participate in the exam or retake without a valid registration in My Studymap.
