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…
Measuring the cosmological background of relativistic particles with WMAP
Patrick Crotty, Julien Lesgourgues, Sergio Pastor
We show that the first year results of the Wilkinson Microwave Anisotropy Probe (WMAP) constrain very efficiently the energy density in relativistic particles in the universe. We d…
Enhanced signal of astrophysical tau neutrinos propagating through Earth
John F. Beacom, Patrick Crotty, Edward W. Kolb
Earth absorbs $\nue$ and $\numu$ of energies above about 100 TeV. As is well-known, although $\nutau$ will also disappear through charged-current interactions, the $\nutau$ flux wi…
