This is a recording of a panel event run by the organisers of the Cosmology from Home conference series: https://cosmologyfromhome.com/

The topic was a comparison of the relative merits of “full shape” and “template” methods to analyse galaxy clustering data. Essentially the difference comes down to whether you consider the entire power spectrum as a whole and fit to it in all its glory, or break into separate pieces that encapsulate specific physics effects.

Each method has its own merits and issues.

The three panelists were:

Héctor Gil Marín: https://www.ub.edu/bispectrum

Marko Simonovic: https://theory.cern/roster/simonovic-marko

Tilman Tröster: https://tilman.troester.space

The papers that came up in discussion were:

ShapeFit: Extracting the power spectrum shape information in galaxy surveys beyond BAO and RSD: https://arxiv.org/abs/2106.07641

The Completed SDSS-IV Extended Baryon Oscillation Spectroscopic Survey: N-body Mock Challenge for the Quasar Sample: https://arxiv.org/abs/2007.09003
