Bounds on isocurvature perturbations from CMB and LSS data
P. Crotty, J. Garcia-Bellido, J. Lesgourgues +1
We obtain very stringent bounds on the possible cold dark matter, baryon and neutrino isocurvature contributions to the primordial fluctuations in the Universe, using recent cosmic…

Does the small CMB quadrupole moment suggest new physics?
James M. Cline, Patrick Crotty, Julien Lesgourgues
Motivated by WMAP's confirmation of an anomalously low value of the quadrupole moment of the CMB temperature fluctuations, we investigate the effects on the CMB of cutting off the…
