Current cosmic microwave background (CMB) bounds on the sum of the neutrino masses assume a sudden reionization scenario described by a single parameter that determines the onset of reionization. We i...
Impact of Instrumental Systematics on the CMB Bispectrum
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/28
We study the effects of instrumental systematics on the estimation of primordial non-Gaussianity using the cosmic microwave background (CMB) bispectrum from both the temperature and the polarization a...
Large Scale Traces of Solar System Cold Dust on CMB Anisotropies
Cosmology and Extragalactic Astrophysics (astro-ph.CO) Earth and Planetary Astrophysics (astro-ph.EP)
2010/12/24
We explore the microwave anisotropies at large angular scales produced by the emission from cold and large dust grains, expected to exist in the outer parts of the Solar System, using a simple toy mod...
