About the course
Course content
The goal of the course is to familiarize the students with the instruments, methods and techniques used in modern observational astrophysics.
In the first part of the course, we introduce the basic tools and concepts needed to observe the Universe from the Earth. We review different types of telescopes used to collect light throughout the electromagnetic spectrum, both from space and from the ground. We present detectors designed to precisely measure different properties of the collected photons (time of arrival, energy / frequency / wavelength and angular position in the sky). We then review the main astronomical techniques used to extract such information, with the final goal of determining physical parameters of planets, stars and galaxies.
Learning outcome
Knowledge:
Upon successful completion of this course, students should understand the different time and coordinate systems used in astronomy, and learn how the main telescopes and detectors work across the electromagnetic spectrum.
Skills:
The students should develop data analysis skills applied to astronomical observations within a Linux/Unix operating system. They should master optical photometric and spectroscopic techniques, as well as Fourier techniques applied to astronomical time series.
General Competence:
The students should learn how to understand and interpret real data from astronomical sources. They should also learn how to design, develop and present a research project working in a team.
Learning methods and activities
Lectures and problem sessions. One special lecture at the planetarium (Trondheim's science center, if available). Data analysis (Astro-LAB) sessions. Observation project with the Nordic Optical Telescope (remote observations designed, performed and analyzed by the students).
Further on evaluation
Evaluation parts: Written exam (50%), project (30%) and lab (20%). To pass the course, all three parts must be passed separately. When lectures are given in English, the exam will be given in English only. The re-sit examination (in August) may be changed from written to oral.
Claims for justification and/or complaints about grades are processed after the final grade for the course is available.
Recommended previous knowledge
Knowledge of physics and mathematics equivalent to about three years study of university physics. FY2450 Astrophysics and TFY4195 Optics, or similar.
