The cosmic flic

These movies show how cosmological parameters affect cosmic clumping, quantified by the red power spectum curves plotted. To make a parameter change, click on it. Click to the left of it for slow motion. Measured data shown is from Planck (upper panels) and and SDSS (bottom). Dashed CMB curves show scalar and tensor components (in At and nt movies only). Dashed matter power is linear, solid is non-linear.

I made a 1st version of these in 2003. They were kindly updated and improved by Chris Williams in 2009 and by Ioana Zelko in 2013.
