Probing neutrino masses with CMB lensing extraction
Abstract
We evaluate the ability of future cosmic microwave background (CMB) experiments to measure the power spectrum of large scale structure using quadratic estimators of the weak lensing deflection field. We calculate the sensitivity of upcoming CMB experiments such as BICEP, QUaD, BRAIN, ClOVER and Planck to the nonzero total neutrino mass M{sub {nu}} indicated by current neutrino oscillation data. We find that these experiments greatly benefit from lensing extraction techniques, improving their onesigma sensitivity to M{sub {nu}} by a factor of order four. The combination of data from Planck and the SAMPAN minisatellite project would lead to {sigma}(M{sub {nu}}){approx}0.1 eV, while a value as small as {sigma}(M{sub {nu}}){approx}0.035 eV is within the reach of a space mission based on bolometers with a passively cooled 34 m aperture telescope, representative of the most ambitious projects currently under investigation. We show that our results are robust not only considering possible difficulties in subtracting astrophysical foregrounds from the primary CMB signal but also when the minimal cosmological model ({lambda} Mixed Dark Matter) is generalized in order to include a possible scalar tilt running, a constant equationofstate parameter for the dark energy and/or extra relativistic degrees of freedom.

We discuss the synergy of the cosmic shear and CMB lensing experiments to simultaneously constrain the neutrino mass and dark energy properties. Taking fully account of the CMB lensing, cosmic shear, CMB anisotropies, and their cross correlation signals, we clarify a role of each signal, and investigate the extent to which the upcoming observations by a highangular resolution experiment of CMB and deep galaxy imaging survey can tightly constrain the neutrino mass and dark energy equationofstate parameters. Including the primary CMB information as a prior cosmological information, the Fisher analysis reveals that the time varying equationofstate parameters, given by w(a)more »

Cluster masses from CMB and galaxy weak lensing
Gravitational lensing can be used to directly constrain the projected density profile of galaxy clusters. We discuss possible future constraints using lensing of the cosmic microwave background (CMB) temperature and polarization, and compare to results from using galaxy weak lensing. We model the moving lens and kinetic SunyaevZel'dovich signals that confuse the temperature CMB lensing when cluster velocities and angular momenta are unknown, and show how they degrade parameter constraints. The CMB polarization cluster lensing signal is {approx}1 {mu}K for massive clusters and challenging to detect; however it should be significantly cleaner than the temperature signal and may provide themore » 
Measuring galaxy cluster masses with CMB lensing using a Maximum Likelihood estimator: statistical and systematic error budgets for future experiments
We develop a Maximum Likelihood estimator (MLE) to measure the masses of galaxy clusters through the impact of gravitational lensing on the temperature and polarization anisotropies of the cosmic microwave background (CMB). We show that, at low noise levels in temperature, this optimal estimator outperforms the standard quadratic estimator by a factor of two. For polarization, we show that the Stokes Q/U maps can be used instead of the traditional E and Bmode maps without losing information. We test and quantify the bias in the recovered lensing mass for a comprehensive list of potential systematic errors. Using realistic simulations, wemore »Cited by 1

CMB lensing extraction and primordial nonGaussianity
The next generation of CMB experiments should get a better handle on cosmological parameters by mapping the weak lensing deflection field, which is separable from primary anisotropies thanks to the nonGaussianity induced by lensing. However, the generation of perturbations in the Early Universe also produces a level of nonGaussianity which is known to be small, but can contribute to the anisotropy trispectrum at the same level as lensing. In this work, we study whether the primordial nonGaussianity can mask the lensing statistics. We concentrate only on the ''temperature quadratic estimator'' of lensing, which will be nearly optimal for the Planckmore »
