Halo bias in Lagrangian Space: Estimators and theoretical predictions
Chirag Modi, Emanuele Castorina, Uros Seljak
We present several methods to accurately estimate Lagrangian bias parameters and substantiate them using simulations. In particular, we focus on the quadratic terms, both the local…
Excursion set peaks: the role of shear
Emanuele Castorina, Aseem Paranjape, Oliver Hahn +1
Recent analytical work on the modelling of dark halo abundances and clustering has demonstrated the advantages of combining the excursion set approach with peaks theory. We extend…
Constraints on halo formation from cross-correlations with correlated variables
Emanuele Castorina, Aseem Paranjape, Ravi K. Sheth
Cross-correlations between biased tracers and the dark matter field encode information about the physical variables which characterize these tracers. However, if the physical varia…
Simulating cosmologies beyond CDM with PINOCCHIO
Luca Alberto Rizzo, Francisco Villaescusa-Navarro, Pierluigi Monaco +4
We present a method that extends the capabilities of the PINpointing Orbit-Crossing Collapsed HIerarchical Objects (PINOCCHIO) code, allowing it to generate accurate dark matter ha…
Baryon Acoustic Oscillations reconstruction with pixels
Andrej Obuljen, Francisco Villaescusa-Navarro, Emanuele Castorina +1
Gravitational non-linear evolution induces a shift in the position of the baryon acoustic oscillations (BAO) peak together with a damping and broadening of its shape that bias and…
On the spatial distribution of neutral hydrogen in the Universe: bias and shot-noise of the HI Power Spectrum
Emanuele Castorina, Francisco Villaescusa-Navarro
The spatial distribution of neutral hydrogen (HI) in the Universe contains a wealth of cosmological information. The 21 cm emission line can be used to map the HI up to very high r…
