CMBPol Mission Concept Study: Gravitational Lensing
Kendrick M. Smith, Asantha Cooray, Sudeep Das +10
Gravitational lensing of the cosmic microwave background by large-scale structure in the late universe is both a source of cosmological information and a potential contaminant of p…
CMBPol Mission Concept Study: Prospects for polarized foreground removal
J. Dunkley, A. Amblard, C. Baccigalupi +28
In this report we discuss the impact of polarized foregrounds on a future CMBPol satellite mission. We review our current knowledge of Galactic polarized emission at microwave freq…
CMB polarimetry with BICEP: instrument characterization, calibration, and performance
Yuki D. Takahashi, Denis Barkats, John O. Battle +22
BICEP is a ground-based millimeter-wave bolometric array designed to target the primordial gravity wave signature on the polarization of the cosmic microwave background (CMB) at de…
A fast Bayesian approach to discrete object detection in astronomical datasets - PowellSnakes I
Pedro Carvalho, Graca Rocha, M. P. Hobson
A new fast Bayesian approach is introduced for the detection of discrete objects immersed in a diffuse background. This new method, called PowellSnakes, speeds up traditional Bayes…
What can be learned from the lensed cosmic microwave background B-mode polarization power spectrum?
Sarah Smith, Anthony Challinor, Graca Rocha
The effect of weak gravitational lensing on the cosmic microwave background (CMB) temperature anisotropies and polarization will provide access to cosmological information that can…
Constraints on changes in fundamental constants from a cosmologically distant OH absorber/emitter
N. Kanekar, C. L. Carilli, G. I. Langston +7
We have detected the four 18cm OH lines from the gravitational lens toward PMN J0134-0931. The 1612 and 1720 MHz lines are in conjugate absorption and emission, prov…
