Astrophysical Data Analyses

• use a computer with the Linux command line system and shell-scripts
• search through scientific databases and archives for specific instrument data
• perform scientific analysis of astronomical data across the electromagnetic spectrum
• reduce X-ray, optical, millimeter wavelength and radio data
• examine astrophysical data with dedicated methods and tools
• assess data quality from a statistical perspective
• exploit observation products such as images, light-curves, and spectra
• utilize fitting techniques to apply a model or mathematical function to data
• solve real astrophysical problems and tailored exercises
• interpret, evaluate and describe the results.

The course starts with an introduction to the use of the Linux command-line system (incl. scripts), followed by basic knowledge about astronomical detectors, calibration, measurement significance, and noise sources. The participants are trained in reducing imaging and spectroscopic data and performing photometry. The students learn about single-dish and interferometric observations at millimetres and radio wavelengths and get to reduce and analyze continuum and spectroscopic data. X-ray data from currently flying X-ray instruments (e.g. NuSTAR, INTEGRAL, NICER) are provided and analyzed to generate scientific products (images, light curves, and spectra). All lectures are followed by hands-on exercises based on the methods and techniques described during the lectures. Example applications include analyzing the spectra of galaxies and supernova explosions, applying techniques to find exoplanets, measuring the molecular content of distant galaxies, and studying thermonuclear explosions on neutron stars.
