Weak lensing, dark matter and dark energy

, 2010
Weak gravitational lensing is rapidly becoming one of the principal probes of dark matter and dark energy in the universe. In this brief review we outline how weak lensing helps determine the structure of dark matter halos, measure the expansion rate of ...

Emergent dark energy from dark matter [PDF]

Physical Review D, 2018
We consider the cosmological dynamics of a scalar field in a potential with multiple troughs and peaks. We show that the dynamics of the scalar field will evolve from light dark matter-like behaviour (such as that of a light axion) to a combination of heavy dark matter-like and dark energy-like behaviour.

Determination of resonances in Gamow window for 12C+12C fusion reaction via thick-target inverse kinematics method

Physics Letters B
The 12C+12C fusion reaction at deep subbarrier energies is important for understanding the carbon burning process in massive star and explosive binary systems.

Constraints on the Coupling between Dark Energy and Dark Matter from CMB data

, 2016
We investigate a phenomenological non-gravitational coupling between dark energy and dark matter, where the interaction in the dark sector is parameterized as an energy transfer either from dark matter to dark energy or the opposite.

Coupling q-Deformed Dark Energy to Dark Matter

Advances in High Energy Physics, 2016
We propose a novel coupled dark energy model which is assumed to occur as a q-deformed scalar field and investigate whether it will provide an expanding universe phase. We consider the q-deformed dark energy as coupled to dark matter inhomogeneities.

Archimedean-type force in a cosmic dark fluid: III. Big Rip, Little Rip and Cyclic solutions

, 2012
We analyze late-time evolution of the Universe in the framework of the self-consistent model, in which the dark matter is influenced by the Archimedean-type force proportional to the four-gradient of the dark energy pressure.

Quantum Haplodynamics, Dark Matter, and Dark Energy

Advances in High Energy Physics, 2014
In quantum haplodynamics (QHD) the weak bosons, quarks, and leptons are bound states of fundamental constituents, denoted as haplons. The confinement scale of the associated gauge group SU(2)h is of the order of Λh≃0.3 TeV.

Interacting Holographic Generalized Chaplygin Gas in compact Kaluza-Klein cosmology

, 2013
We investigate Holographic Dark Energy Correspondence of Interacting Generalized Chaplygin Gas model in the framework of compact Kaluza-Klein cosmology. The evolution of the modified holographic dark energy and the equation of state parameter is obtained

Dark group: dark energy and dark matter [PDF]

Physics Letters B, 2004
We study the possibility that a dark group, a gauge group with particles interacting with the standard model particles only via gravity, is responsible for containing the dark energy and dark matter required by present day observations. We show that it is indeed possible and we determine the constrains for the dark group.

Dark Matter and Dark Energy in the Universe

Bibechana, 2014
Cosmological and astronomical observations predict that the present Universe is passing through an accelerating phase of expansion. The Universe emerged out of an exponential phase in the very early Universe.
