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…
Beyond the Damping Tail: Cross-Correlating the Kinetic Sunyaev-Zel'dovich Effect with Cosmic Shear
Olivier Doré, Joseph F. Hennawi, David N. Spergel
Secondary anisotropies of the CMB have the potential to reveal intricate details about the history of our universe between the present and recombination epochs. However, because th…
Terrestrial Planet Finding with a Visible Light Coronagraph
M. J. Kuchner, D. N. Spergel
Directly imaging extrasolar planets using a monolithic optical telescope avoids many pitfalls of space interferometry and opens up the prospect of visible light studies of extrasol…
Circularly Symmetric Apodization via Starshaped Masks
Robert J. Vanderbei, David N. Spergel, N. Jeremy Kasdin
Recently, we introduced a class of shaped pupil masks, called spiderweb masks, that produce point spread functions having annular dark zones. With such masks, a single image can be…
First Year Wilkinson Microwave Anisotropy Probe (WMAP) Observations: Dark Energy Induced Correlation with Radio Sources
M. R. Nolta, E. L. Wright, L. Page +10
The first-year WMAP data, in combination with any one of a number of other cosmic probes, show that we live in a flat Λ-dominated CDM universe with Ω_m ~ 0.27 and Ω_Λ~ 0.73. In thi…
Measuring primordial non-Gaussianity in the cosmic microwave background
Eiichiro Komatsu, David N. Spergel, Benjamin D. Wandelt
We derive a fast way for measuring primordial non-Gaussianity in a nearly full-sky map of the cosmic microwave background. We find a cubic combination of sky maps combining bispect…
Spiderweb Masks for High-Contrast Imaging
Robert J. Vanderbei, David N. Spergel, N. Jeremy Kasdin
Motivated by the desire to image exosolar planets, recent work by us and others has shown that high-contrast imaging can be achieved using specially shaped pupil masks. To date, th…
Design, Implementation and Testing of the MAP Radiometers
N. Jarosik, C. L. Bennett, M. Halpern +12
The Microwave Anisotropy Probe (MAP) satellite, launched June 30, 2001, will produce full sky maps of the cosmic microwave background radiation in 5 frequency bands spanning 20 - 1…
First Year Wilkinson Microwave Anisotropy Probe (WMAP) Observations: On-Orbit Radiometer Characterization
N. Jarosik, C. Barnes, C. L. Bennett +11
The WMAP satellite has completed one year of measurements of the Cosmic Microwave Background (CMB) radiation using 20 differential high-electron-mobility-transistor (HEMT) based ra…
First Year Wilkinson Microwave Anisotropy Probe (WMAP) Observations: Data Processing Methods and Systematic Errors Limits
G. Hinshaw, C. Barnes, C. L. Bennett +14
We describe the calibration and data processing methods used to generate full-sky maps of the cosmic microwave background (CMB) from the first year of Wilkinson Microwave Anisotrop…
First Year Wilkinson Microwave Anisotropy Probe (WMAP) Observations: Angular Power Spectrum
G. Hinshaw, D. N. Spergel, L. Verde +14
We present the angular power spectrum derived from the first-year Wilkinson Microwave Anisotropy Probe (WMAP) sky maps. We study a variety of power spectrum estimation methods and…
First Year Wilkinson Microwave Anisotropy Probe (WMAP) Observations: Implications for Inflation
H. V. Peiris, E. Komatsu, L. Verde +12
We confront predictions of inflationary scenarios with the WMAP data, in combination with complementary small-scale CMB measurements and large-scale structure data. The WMAP detect…

L. Page, M. R. Nolta, C. Barnes +12
The CMB has distinct peaks in both its temperature angular power spectrum (TT) and temperature-polarization cross-power spectrum (TE). From the WMAP data we find the first peak in…
