Decaying particles and the reionization history of the Universe
Elena Pierpaoli
We investigate the possibility that the Universe is reionized by the decay products of heavy particles. In particular we study under which circumstances this decay may produce a si…
Measurement of the Sunyaev-Zel'dovich Increment in Massive Galaxy Clusters
Michael Zemcov, Mark Halpern, Colin Borys +4
We have detected the Sunyaev-Zel'dovich (SZ) increment at 850 microns in two galaxy clusters (Cl 0016+16 and MS 1054.4-0321) using SCUBA (Sub-millimetre Common User Bolometer Array…
Constraints on the cosmic neutrino background
Elena Pierpaoli
The radiative component of the Universe has a characteristic impact on both large scale structure (LSS) and the cosmic microwave background radiation (CMB). We use the recent WMAP…
Point sources in the MAP sky maps
Elena Pierpaoli
We discuss point sources foregrounds for the MAP experiment. We consider several possible strategies for removing them and we assess how the statistics of the CMB signal are affect…
