Simulations of dark energy cosmologies
… such as the growth of large scale structure, the halo mass function and baryonic acoustic oscillations. We study the power spectrum in redshift space in $\Lambda$CDM and quintessence dark energy models and test predictions for the form of the redshift space distortions. An improved model for the …

GALAXY-HALO CONNECTION AND CLUSTERING IN THE PRESENCE OF DYNAMICAL DARK ENERGY AND MASSIVE NEUTRINOS
… of the connection between dark matter subhaloes and galaxies, and the analysis of the galaxy cluster mass function and clustering, in cosmologies alternative to the standard LCDM model. To this aim a large set of cosmological N-body simulations has been used, the so-called “Dark Energy and …

The Role of Baryons and Neutrinos in the Evolution of Large-Scale Structure
… is the effect of the cosmic background of massive neutrinos. As these remain relativistic to relatively late times, they will free-stream out of overdensities, altering the formation of large-scale structure (LSS). If this effect can be accurately modelled, it presents an independent method …

Cosmology with Velocity Dispersion based Counts of Groups and the Effect of AGN Feedback on Host Galaxy Morphology
… problem is systematic errors in the absolute halo mass calibration in cluster studies, which is required to convert the standard theoretical prediction (the halo mass function) into counts as a function of the observable (e.g., X-ray luminosity, Sunyaev-Zel'dovich flux, optical richness). Here …
