Astrophysics > Cosmology and Nongalactic Astrophysics

|
By De Boer, van Waerbeke
| arXiv
Intrinsic alignments (IA) of galaxies are a dominant source of systematics in weak-lensing cosmological analyses, and direct measurements on spectroscopic samples are the primary source of priors on their amplitude.

On constraining Cosmology and the Halo Mass Function with Weak Gravitational Lensing.

|
By ENSTA Paris, Boulevard des Maréchaux, Cottingham Road, van Waerbeke
| Oxford University Press (OUP)
The discrepancy between the weak lensing (WL) and the Planck measurements of S has been a subject of several studies. Assuming that residual systematics are not the cause, these studies tend to show that a strong suppression of the amplitude of the mass power spectrum P(k) in the late universe at high k could resolve it. The WL signal at the small scale is sensitive to various effects not related to lensing, such as baryonic effects and intrinsic alignment.
