Program:
Lecture 1 - Intro - electromagnetic signal, photon vs wave,
distances, coordinates, fluxes vs luminosities vs magnitude,
instrument structure (properties and atmospheric limits),
sensitivity, resolution (ang & spect), polarimetry
Lecture 2 - Continuum - broad band signals, spectral indices, colors,
SED fitting, photometric redshift, cross-matches
- Radio interferometry
Lecture 3 - Spectroscopy - line definition, critical density,
main lines (HII, CO, molecules, PAH, CII, OIII, NII,
Hrecombination series, X-ray lines),
momenta, ratios, spectroscopic redshift determination,
line flux density, Lyman break technique
- Optical-IR spectroscopic techniques
Lecture 4 - Cosmological probers and other carriers: CMB & foregrounds removal
GW (pulsar timing arrays + GW detectors)
neutrinos
- Writing an observational paper
Lecture 5 - Open Science - Archives & VO tools - Visualization tools (with tutorials)
Lecture 6 - Calibration and Imaging, Noise and sistematics - Gaussian vs non Gaussian noise, Confusion noise, Eddington bias, Malmquist bias, instrumental systematics
Lecture 7 - Surveys vs small samples - detections, reliability, completeness, stacking, statistical analysis (luminosity fuction, redshift distribution, number counts), upper and lower limits, survival analysis, small numbers statistics
Exam: Present to the class (in max 10min and 4 slides) the analysis of data of your favourite band, telescope, target[s], no need to perform calibration, extract values for science
