Simulations of dark energy cosmologies
… 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 redshift space power …

Constraining dark energy using real and mock galaxy surveys
… of dark energy in the survey via the baryonic acoustic oscillations. We explore the challenges of using the ISW effect as a constraint on dark energy. In particular, we investigate the effect of non-linear gravitational evolution, using N-body simulations. We have quantified the …

BIANCHI-ICOSMOLOGICALMODEL IN f(R,T) GRAVITY
… lensing, the Sloan Digital Sky Survey (SDSS), baryonic acoustic oscillations (BAO), and PLANCK, has drastically ameliorated cosmology; thus, providing a deeper understanding of the universe. These observations suggest that the universe is currently undergoing an accelerated expansion, where two …

Phase-space reconstructions of cosmic velocities and the cosmic web
… and can be used for improved analyses of the baryonic acoustic oscillations, environmental studies of the cosmic web, the kinematic Sunyaev-Zel’dovic or integrated Sachs-Wolfe effect.

Computational Bayesian techniques applied to cosmology
… peak around redshift $z = 0.2$ due to baryonic acoustic oscillation and supernovae data constraints, whilst cosmic microwave background radiation and Lyman-$\alpha$ forest constraints are less significant. Specific models with a conformal time symmetry in the Friedmann equation and with …
