Prerequisites
No specific prerequisites are set for this course, but it is advisable to possess some basic knowledge of Astronomy and Physics.
Objectives and Contextualisation
The objective of this course is to familiarize the student with the various techniques for observations as used in Astronomy. The student will be required to comprehend basic concepts, nomenclature and unit systems that are commonly employed in astronomical work. Detection techniques and instrumentation will be described as a function of wavelength, including the entire particle and electromagnetic spectrum: neutrino astronomy, gravitational waves, high-energy (gamma-rays and X-rays), UV-optical, near infrared and radio astronomy. For all these regimes, which use different methodologies, data reduction and analysis techniques will be covered. The final goal is that the student acquires sufficient basic knowledge to be able to plan, execute and analyze observations in all branches of Astronomy thus enabling him/her to perform scientific research.
Competences
- Apply the main principles to specific areas such as particle physics, astrophysics of stars, planets and galaxies, cosmology and physics beyond the Standard Model.
- Formulate and tackle problems, both open and more defined, identifying the most relevant principles and using approaches where necessary to reach a solution, which should be presented with an explanation of the suppositions and approaches.
- Understand the bases of advanced topics selected at the frontier of high energy physics, astrophysics and cosmology and apply them consistently.
- Use acquired knowledge as a basis for originality in the application of ideas, often in a research context.
- Use critical reasoning, analytical capacity and the correct technical language and formulate logical arguments.
Learning Outcomes
- Apply the optical principle of the conceptual design of astronomical cameras and telescopes.
- Make a comparative analysis of the different observation techniques (optical astronomy, radioastronomy, etc.).
- Plan an optical observation of a series of astronomical objects.
- Understand the basics of astronomical observations.
- Understand the basics of optical and infrared astronomy.
- Understand the basics of radioastronomy.
