Computational Astrophysics



The MSc course in Computational Astronomy will concentrate on data and how to process it.
General lore:

  • Good vs bad data
  • Some traps:
  • Poorly-orthogonal bases
  • Splines

Software:

  • When to trust it
  • Good vs evil (= how to write maintainable code)
  • Scripting (perl, python)

Statistics and source/signal detection:

  • Gaussian vs Poisson
  • Bayesian vs frequentist
  • Significance
  • Reliability vs completeness
  • Sensitivity
  • Surveys: volume- vs flux-limited
  • Which is the best detection method?
  • Confusion

Radio Interferometry:

  • - Basic theory
  • - Continuum vs spectral-line
  • - Packages (AIPS, Miriad, CASA)
  • - Project: dynamic range issues - weighting, w-term

X-ray:

  • - Instrumentation overview
  • - Event-oriented data
  • - Packages (SAS, Ciao, xspec, ftools, ds9)
  • - Project: trawl for flashers in XMM data
