GALAXY-HALO CONNECTION AND CLUSTERING IN THE PRESENCE OF DYNAMICAL DARK ENERGY AND MASSIVE NEUTRINOS
… on the modelling 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 …

Cosmological constraints using 2- and 3-point correlations with meerkat, the ska and other surveys
… growth function, and what they mean for dynamical dark energy and modified gravity. We account for telescope beam effects, instrumental noise, foreground avoidance, the Alcock-Paczynski effect, and theoretical modeling errors in the correlators. The investigation also includes assessments …

Unusual Matter Models in Cosmology
… third section, we study a related model, called Energy-Momentum Log Gravity (EMLG), constructed by the addition of the term f(TμνTμν) = α ln(λ TμνTμν) to the Einstein-Hilbert action with cosmological constant Λ. This choice of model results in constant effective inertial mass density and has an …

Investigating the properties of gamma ray bursts and gravitational wave standard sirens as high redshift distance indicators
… in the shape of Conformal Gravity and Unified Dark Matter through a widely applicable and transferable Bayesian model comparison technique and the development of a representative mock data set. Finally, we investigate gravitational wave standard sirens as an alternative high-redshift distance …
