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…
Non-zero density-velocity consistency relations for large scale structures
Luca Alberto Rizzo, David F. Mota, Patrick Valageas
We present exact kinematic consistency relations for cosmological structures that do not vanish at equal times and can thus be measured in surveys. These rely on cross-correlations…
Supersymmetric chameleons and ultra-local models
Philippe Brax, Luca Alberto Rizzo, Patrick Valageas
Super-chameleon models where all types of matter belong to three secluded sectors, i.e. the dark, supersymmetry breaking and matter sectors, are shown to be dynamically equivalent…
Ultra-local models of modified gravity without kinetic term
Philippe Brax, Luca Alberto Rizzo, Patrick Valageas
We present a class of modified-gravity theories which we call ultra-local models. We add a scalar field, with negligible kinetic terms, to the Einstein-Hilbert action. We also intr…
