Module aims

This module will discuss the theory and practice of modern observational astronomy across the electromagnetic spectrum. The module will begin with a review of classical electromagnetism and radiation physics, before looking in detail at the physics, technology and techniques of used to detect astronomical light at different wavelengths. The physics of thermal and non-thermal emission will be examined, along with examples of astronomical sources of such radiation. The importance of multiwavelength observations will be explored through various examples and demonstrated through the production of false-colour images of astronomical phenomena using real multiwavelength data. Finally, the module will focus on the physics of pulsars and their emission in the radio and X-ray regimes, which will also form the basis of the main summative assessment. Students will develop their skills in applied mathematics, problem-solving, image analysis, and scientific investigation.

Module learning outcomes

At the conclusion of the module students will be able to:

  • Understand the classical electromagnetism and fundamental radiation physics relevant to modern observational astronomy
  • Explain the physics and statistics which underpin the detection of astronomical radiation at different wavelengths
  • Describe the different tools and techniques used in multiwavelength astronomy, including the principle of interferometry
  • Discuss the difficulties faced by astronomers making observations in different regions of the electromagnetic spectrum and how they may be overcome
  • Explain the origin of thermal and non-thermal emission, including MASER emission, in terms of thermodynamics and quantum mechanics
  • Understand the knowledge that can be gained by observing the same celestial objects and phenomena at different wavelengths
  • Discuss observations of the Sun and the Milky Way in different regions of the electromagnetic spectrum
  • Describe the astrophysics of pulsars and their multiwavelength emission
  • Produce an infographic explaining the physics and technology of an observational facility
  • Produce composite false-colour images of astronomical phenomena using multiwavelength data
  • Undertake a laboratory investigation related to pulsars and present the findings in a laboratory report
