Syllabus content
The basics: advances in astronomy and relationship with technology; review of interaction of radiation with matter; review of EM principles and radiation theory; key concepts in measurement.
Photometry or Spectroscopy: physics of particular sources; continuum and line radiation.
Telescopes and Optics: fundamental and practical criteria; geometrical optics (IR-UV); Gaussian optics (radio-FIR); throughput; image quality; Antennae (radio), dish (radio-UV), grazing incidence (X-ray) telescopes; interferometry; review current state of the art research facilities.
Detection: Measurement concepts (linearity, dynamic range, frequency range, speed of observation, etc.); fundamental limits to sensitivity; noise; detection capabilities across EM wavebands.
Spectometry: orbital or sub-orbital observation; Radio devices; FTS or gratings systems; FPs; X & γ-ray instruments.
Interferometry: EM; non EM - GW input here?
Instrument design: Consider 4 real instruments (i.e. case studies of Radio, IR, optical and X-ray instruments); illustrate the basic concepts inherent in the instrument design; understand instrumental limitations are detection choices.
Instrument modelling: modelling a typical source to determine observable signals; development of end-to-end instrument models; use of a dummy source; feedback to instrument design; calibration.
Cataloguing: archiving observations; accessibility and databases.
