Anthropic predictions for vacuum energy and neutrino masses in the light of WMAP-3
Levon Pogosian, Alexander Vilenkin
Anthropic probability distributions for the cosmological constant and for the sum of neutrino masses are updated using the WMAP-3 data release. The new distribution for Lambda is i…
Dynamics of Linear Perturbations in f(R) Gravity
Rachel Bean, David Bernat, Levon Pogosian +2
We consider predictions for structure formation from modifications to general relativity in which the Einstein-Hilbert action is replaced by a general function of the Ricci scalar.…
On vector mode contribution to CMB temperature and polarization from local strings
Levon Pogosian, Ira Wasserman, Mark Wyman
In a recent publication, we used the data from WMAP and SDSS to constrain the primordial perturbations and to predict the B-mode polarization sourced by cosmic string networks. We…
