Large Scale Plane-Mirroring in the Cosmic Microwave Background WMAP5 Maps
V. G. Gurzadyan, A. A. Starobinsky, T. Ghahramanyan +5
We continue investigation of the hidden plane-mirror symmetry in the distribution of excursion sets in cosmic microwave background (CMB) temperature anisotropy maps, previously not…
Two new diagnostics of dark energy
Varun Sahni, Arman Shafieloo, Alexei A. Starobinsky
We introduce two new diagnostics of dark energy (DE). The first, Om, is a combination of the Hubble parameter and the cosmological redshift and provides a "null test" of dark energ…
Is a step in the primordial spectral index favored by CMB data ?
Minu Joy, Arman Shafieloo, Varun Sahni +1
A sudden small change in the second derivative of the inflaton potential can result in a universal local feature in the spectrum of primordial perturbations generated during inflat…
