The observed distribution of galaxies

Henry Joy McCRACKEN
Institut d'Astrophysique de Paris

In my talks I will present a review of the statistical properties of the observed galaxy distribution as determined from sky surveys. I will describe what each measurement can tell us about the underlying galaxy distribution and how it relates to the galaxy's intrinsic properties. I will describe all of the methods currently in use in deep sky surveys and outline their advantages and drawbacks. My presentation will describe, but not be limited to:
  • Angular projected two-point clustering statistics in the local and high-redshift universe for a range of galaxy populations
  • Clustering in real and redshift space with spectroscopic surveys at low and high redshifts
  • Clustering with photometric redshifts and photometrically selected galaxy surveys
  • Counts in cells methods and higher order clustering measurements
In my seminar, I will present new measurements of the clustering of galaxies at intermediate and high redshifts based on results from the Canada-France legacy survey.
