Extending the WMAP Bound on the Size of the Universe
Joey Shapiro Key, Neil J. Cornish, David N. Spergel +1
Clues to the shape of our Universe can be found by searching the CMB for matching circles of temperature patterns. A full sky search of the CMB, mapped extremely accurately by NASA…
Statistical Isotropy of the Wilkinson Microwave Anisotropy Probe Data: A Bipolar Power Spectrum Analysis
Amir Hajian, Tarun Souradeep, Neil Cornish
The statistical expectation values of the temperature fluctuations of the Cosmic Microwave Background (CMB) are assumed to be preserved under rotations of the sky. We investigate t…
Constraining the Topology of the Universe
Neil J. Cornish, David N. Spergel, Glenn D. Starkman +1
The first year data from the Wilkinson Microwave Anisotropy Probe are used to place stringent constraints on the topology of the Universe. We search for pairs of circles on the sky…
LISA data analysis: Source identification and subtraction
Neil J. Cornish, Shane L. Larson
The Laser Interferometer Space Antenna (LISA) will operate as an AM/FM receiver for gravitational waves. For binary systems, the source location, orientation and orbital phase are…
Journey to the edge of time: The GREAT mission
Neil J. Cornish, David N. Spergel, Charles L. Bennett
We are surrounded by radiation that originated from the big bang. It has traveled to us from the farthest reaches of the Universe, carrying with it an unaltered record of the begin…
Mapping the gravitational wave background
Neil J. Cornish
The gravitational wave sky is expected to have isolated bright sources superimposed on a diffuse gravitational wave background. The background radiation has two components: a confu…
