Super-sample covariance of the power spectrum, bispectrum, halos, voids, and their cross covariances
Adrian E. Bayer, Jia Liu, Ryo Terasawa +3
We study the effect of super-sample covariance (SSC) on the power spectrum and higher-order statistics: bispectrum, halo mass function, and void size function. We also investigate…
Assembly bias in the local PNG halo bias and its implication for constraints
Titouan Lazeyras, Alexandre Barreira, Fabian Schmidt +1
We use -body simulations to study halo assembly bias (i.e., the dependence of halo clustering on properties beyond total mass) in the density and primordial non-Gaussianity (PNG…
Can we actually constrain using the scale-dependent bias effect? An illustration of the impact of galaxy bias uncertainties using the BOSS DR12 galaxy power spectrum
Alexandre Barreira
The scale-dependent bias effect on the galaxy power spectrum is a very promising probe of the local primordial non-Gaussianity (PNG) parameter , but the amplitude of th…
Response approach to the integrated shear 3-point correlation function: the impact of baryonic effects on small scales
Anik Halder, Alexandre Barreira
The integrated shear 3-point correlation function is a higher-order statistic of the cosmic shear field that describes the modulation of the 2-point correlation function…
