Correlations of Cosmic Tidal Fields
Paolo Catelan, Cristiano Porciani
We study correlations amongst tidal fields originated by the large-scale distribution of matter in the Universe. The two-point tidal correlation is described as a rank-4 tensor, wh…
Two Ways of Biasing Galaxy Formation
Paolo Catelan, Cristiano Porciani, Marc Kamionkowski
We calculate the galaxy bispectrum in both real and redshift space adopting the most common prescriptions for local Eulerian biasing and Lagrangian evolving-bias model. We show tha…
Intrinsic and Extrinsic Galaxy Alignment
Paolo Catelan, Marc Kamionkowski, Roger D. Blandford
We show with analytic models that the assumption of uncorrelated intrinsic ellipticities of target sources that is usually made in searches for weak gravitational lensing due to la…
