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…
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…
On the origin of the cosmic microwave background anisotropies
Ria Follop, Anais Rassat, Asantha Cooray +1
Suggestions have been made that the microwave background observed by COBE and WMAP and dubbed Cosmic Microwave Background (CMB) may have an origin within our own Galaxy or Earth. T…
Statistical Imprints of SZ Effects in the Cosmic Microwave Background
Asantha Cooray, Daniel Baumann, Kris Sigurdson
We review several aspects of the Sunyaev-Zel'dovich (SZ) effect associated with the large scale baryon distribution and its characteristic signatures in the statistics of cosmic mi…
Search for Small-Mass Black Hole Dark Matter with Space-Based Gravitational Wave Detectors
Naoki Seto, Asantha Cooray
The high sensitivity of upcoming space-based gravitational wave detectors suggests the possibility that if halo dark matter were composed of primordial black holes (PBHs) with mass…
After MAP: Next Generation CMB
Asantha Cooray
We discuss several opportunities involving cosmic microwave background (CMB) observations during the post-MAP era. The curl-modes of CMB polarization allow a direct detection of in…
