Needlet Detection of Features in WMAP CMB Sky and the Impact on Anisotropies and Hemispherical Asymmetries
Davide Pietrobon, Alexandre Amblard, Amedeo Balbi +3
We apply spherical needlets to the Wilkinson Microwave Anisotropy Probe 5-year cosmic microwave background (CMB) dataset, to search for imprints of non-isotropic features in the CM…
Impact of Point Source Clustering on Cosmological Parameters with CMB Anisotropies
Paolo Serra, Asantha Cooray, Alexandre Amblard +2
The faint radio point sources that are unresolved in cosmic microwave background (CMB) anisotropy maps are likely to be a biased tracer of the large-scale structure dark matter dis…
Lensing and Supernovae: Quantifying The Bias on the Dark Energy Equation of State
Devdeep Sarkar, Alexandre Amblard, Daniel E. Holz +1
The gravitational magnification and demagnification of Type Ia supernovae (SNe) modify their positions on the Hubble diagram, shifting the distance estimates from the underlying lu…
Anisotropy Studies of the Unresolved Far-infrared Background
Alexandre Amblard, Asantha Cooray
Dusty, starforming galaxies and active galactic nuclei that contribute to the integrated background intensity at far-infrared wavelengths trace the large-scale structure. Below the…
