Observational signature of sign of cosmological perturbation
Posted: April 20 2015
Hello,
As far as I know, all observational evidence for cosmological perturbations comes from the CMB power spectrum, which goes like [tex]\delta^2[/tex]. Are there any observational signatures that would indicate the sign of [tex]\delta[/tex]?
Thanks for any help,
Kevin
