Observational Astrophysics Workshop 1

The Observational Astrophysics Workshop 1 is an introduction to the observational study (photometry or spectroscopy) of astrophysical objects (stars, nebulae) at M1 level. Students carry out all the steps involved, from planning and carrying out observations at the Faculty of Science's astronomical observatory, to calibrating and analyzing the data obtained. This module is designed as a preparation for the M2 module Observational Astrophysics Workshop 2 (HAP905P).

• Planning astronomical observations
• Acquire usable astronomical photometric or spectroscopic data
• Know the calibration steps, and adapt them to the data
• Implement calibration and data analysis with dedicated software and python scripts
• Propose a simple astrophysical interpretation of the measurements obtained
• Writing a scientific report

• Geometric Optics
• Wave Optics and Electrodynamics
• Newtonian dynamics
• Experimental Physics
• Mathematical tools
• Python for science

Oral

This UE comprises 4 aspects:

• courses and resources to provide students with the knowledge they need to implement an observational study in astrophysics;
• preparation and practical execution of an observation at the Faculty of Science's astronomical observatory;
• calibration and analysis of data acquired in digital form using dedicated software and student-coded Python scripts;
• presentation of the work carried out in compliance with research standards.

Course content :

1. Planning astronomical observations
2. Using CCD detectors for astronomical observation
3. Photometric measurements and calibration in astronomy
4. Spectroscopic measurements and calibration in astronomy
5. Signal analysis in astrophysics
