This paper summarizes the physical mechanisms that encode the type and quantity of cosmological matter in the properties of large-scale structure, and reviews the application of such tests to current datasets. The key lengths of the horizon size at matter-radiation equality and at last scattering determine the total matter density and its ratio to the relativistic density; acoustic oscillations can diagnose whether the matter is collisionless, and small-scale structure or its absence can limit…

Modified Newtonian Dynamics (MOND): Observational Phenomenology and Relativistic Extensions
TLDR
It is shown that many of these puzzling observations are predicted by one single relation — Milgrom’s law — involving an acceleration constant a0 on the order of the square-root of the cosmological constant in natural units.
Local-Group tests of dark-matter concordance cosmology - Towards a new paradigm for structure formation
Predictions of the concordance cosmological model (CCM) of the structures in the environment of large spiral galaxies are compared with observed properties of Local Group galaxies. Five new, most
Quantum statistical entropy and minimal length of 5D Ricci-flat black string with generalized uncertainty principle
In this paper, we study the quantum statistical entropy in a 5D Ricci-flat black string solution, which contains a 4D Schwarzschild-de Sitter black hole on the brane, by using the improved thin-layer
Large Hadron Collider phenomenology of vector-like quarks beyond the Narrow Width Approximation
The topic of this thesis is the phenomenology of Vector-Like Quarks (VLQs) at the Large Hadron Collider (LHC), with a focus on understanding the difference between the commonly adopted experimental
4 Observational Cosmology
I discuss the classical cosmological tests– angular size-redshift, flux-redshift, and galaxy number counts– in the light of the cosmology prescribed by the interpretation of the CMB anisotropies. The
Long-lived quintessential scalar hair
We investigate static configurations of a vacuumless scalar field as ‘hair’ on a black hole. The vacuumless field has run-away behaviour, meaning the scalar potential vanishes only at infinite field
Torsion, Scalar Field, Mass and FRW Cosmology
In the Einstein–Cartan space U4, an axial vector torsion together with a scalar field connected to a local scale factor have been considered. By combining two particular terms from the SO(4, 1)

TLDR
This paper reviews the progress reported at the Discussion Meeting and advertises some possible future directions in the drive to understand dark matter and dark energy, and ideas are presented for calculating the amounts of dark Matter anddark energy and relating them to laboratory data.
