Specific Competition
CE1 - Understand the basic conceptual schemes of Astrophysics
CE4 - Understand the structure and evolution of galaxies
General Competencies
CG2 - Understand the technologies associated with observation in Astrophysics and instrumentation design
CG4 - Evaluate the orders of magnitude and develop a clear perception of physically different situations that show analogies allowing the use, to new problems, of synergies and known solutions
Basic skills
CB6 - Possess and understand knowledge that provides a basis or opportunity to be original in the development and/or application of ideas, often in a research context
CB7 - That students know how to apply the knowledge acquired and their ability to solve problems in new or little-known environments within broader contexts
CB8 - That students are able to integrate knowledge and face the complexity of formulating judgments based on information that, being incomplete or limited, includes reflections on the social and ethical responsibilities linked to the application of their knowledge and judgments
CB10 - That students possess the learning skills that allow them to continue studying in a way that will be largely self-directed or autonomous
Exclusive to the Specialty in Observation and Instrumentation
CX8 - Understand the structure and evolution of nebulae and other large objects
