Observational biases in Lagrangian reconstructions of cosmic velocity fields
G. Lavaux, R. Mohayaee, S. Colombi +3
Lagrangian reconstruction of large-scale peculiar velocity fields can be strongly affected by observational biases. We develop a thorough analysis of these systematic effects by re…
Testing Quintessence models with large-scale structure growth
K. Benabed, F. Bernardeau
We explore the possibility of putting constraints on quintessence models with large-scale structure observations. In particular we compute the linear and second order growth rate o…
CMB B-polarization to map the Large-scale Structures of the Universe
K. Benabed, F. Bernardeau, L. van Waerbeke
We explore the possibility of using the B-type polarization of the CMB to map the large-scale structures of the Universe taking advantage of the lens effects on the CMB polarizatio…
Cosmic Statistics of Statistics
I. Szapudi, S. Colombi, F. Bernardeau
The errors on statistics measured in finite galaxy catalogs are exhaustively investigated. The theory of errors on factorial moments by Szapudi & Colombi (1996) is applied to cumul…
Lensing effect on the relative orientation between the Cosmic Microwave Background ellipticities and the distant galaxies
L. Van Waerbeke, F. Bernardeau, K. Benabed
The low redshift structures of the Universe act as lenses in a similar way on the Cosmic Microwave Background light and on the distant galaxies (say at redshift about unity). As a…
Properties of the Cosmological Density Distribution Function
F. Bernardeau, L. Kofman
The properties of the probability distribution function of the cosmological continuous density field are studied. We present further developments and compare dynamically motivated…
Skewness and Kurtosis in Large-Scale Cosmic Fields
F. Bernardeau
In this paper, I present the calculation of the third and fourth moments of both the distribution function of the large--scale density and the large--scale divergence of the veloci…
The Nonlinear Evolution of Rare Events
F. Bernardeau
In this paper I consider the nonlinear evolution of a rare density fluctuation in a random density field with Gaussian fluctuations, and I rigorously show that it follows the spher…
