Objectives
This curricular unit provides advanced training in relevant topics of current research on the different components of observation and instrumentation in Astronomy, through specific modules in active areas of research and development. The aim is to address in detail the tools and fundamental principles that are necessary for a research activity in this area intervention of modern Astronomy.
The student is expected to acquire knowledge and skills necessary to plan, implement and reduce observations in different wavelengths and to understand the development and operation of astronomical instrumentation used in these observations. The student should also be able to understand the technology used and the methods for collecting information in astronomy and how those observations can be transformed into useful scientific data for research in Astronomy.
Learning outcomes and competences
Each module of the course will be presented by an expert, covering active areas of research and development, so that in specific cases relevant for the future it is possible to address the critical aspects of observation in astronomy and development of instrumentation that are required to implement a thesis project in astronomy with international relevance. The contents of each module are defined to ensure it achieves the objectives of the course that is part of a 3rd cycle in astronomy.

Program
Course splitted in two modules
1) IR photometry
Brief introduction: the beginning of Infrared Astronomy; how to detect IR light;
Observing the Infrared Universe: what can we see?; background contamination; dust extinction; absorption and emission by Earth’s atmosphere; near-, mid- and far-infrared observations;
Infrared Telescopes and observing techniques: ground-based and space telescopes; detectors; instrumental thermal emission; dithering, chopping and nodding; adaptive optics;
Data reduction and analysis: Imaging and photometry; building large mosaics; aperture and PSF photometry; evaluating signal-to-noise;
Writing Proposals: what do we need to know to write a successful proposal;
The future of IR Astronomy: getting ready for JWST; the new instruments; the ground breaking science goals
2) High resolution spectroscopy
CCD detectors; The first step for CCD image reduction; Pipelines tutorial, retrieving data from ESO archives. Demonstration of UVES pipeline; IRAF bsics; Introduction to spectral analysis; Spectral Synthesis methodology

Eligibility for exams
Frequency of 50% of classes
Calculation formula of final grade
The final mark will be computed averaging the marks obtained in the two modules (ie. each module contributes with a weight of 50%).
The classification of each module will depend on the module and will take in consideration the student participation and the practical tasks/exercises.
Classification improvement
There is no option for improving the classification or to repeat the evaluation in this course.
