(syllabus)
Part I: Astrophysics Problem:
Active Galactic Nuclei and Galaxies 1. Definition and classification: BH paradigm, growth, AGN Radio Loud / Radio quiet, Unified Model 2. AGN astrophysics: X-band AGN-RQ properties, emission models: Comptonization, absorption properties and outflows 3. AGN astrophysics: reflection components in the X-band spectrum, observation of relativistic effects in the X-band spectrum 4. Spectra of AGN and Galaxies in the optical and NIR band
Part II: Introduction to X-band and optical detectors and telescopes 1. optical telescopes. Basic principles and techniques of detection 2. X-band detectors: basic principles and detection techniques 3. solid state detectors, Charged Coupled Devices (CCD) 4. collimated and focused optical systems 5. X telescope features: efficiency, sensitivity, energy resolution, angular resolution, effective area 6. The ESA / XMM-Newton, NASA / Chandra and NASA / NuStar space telescopes
Part III: Data Analysis
1. investigation tools: study of energy distribution (emission spectrum), study of temporal behavior (light curve), study of variability (power spectrum and reverberation) 2. statistical errors and systematic errors 3. background 4. S / N signal to noise ratio 5. observation and maximization of the S / N
Part IV: Data analysis tutorial
- XMM-epic session 1. search for archived data 2. Image analysis: DS9 3. spectrum analysis: xspec 4. Temporal analysis: xronos
Part V - data analysis in optical and NIR band
