Observational constraints on variable equation of state parameters of dark matter and dark energy after Planck

open access: yesPhysics Letters B, 2014
In this paper, we study a cosmological model in general relativity within the framework of spatially flat Friedmann–Robertson–Walker space–time filled with ordinary matter (baryonic), radiation, dark matter and dark energy, where the latter two ...

The Impact Of Cold Dark Matter Variants On The Halos Of The First Stars And Galaxies: Angular Momentum And Vortex Creation In BEC Dark Matter [PDF]

open access: yes, 2010
If cold dark matter elementary particles form a Bose-Einstein condensate, their superfluidity may distinguish them from other forms of cold dark matter, including the creation of quantum vortices.

Holographic interacting dark energy in the braneworld cosmology

open access: yes, 2007
We investigate a model of brane cosmology to find a unified description of the radiation-matter-dark energy universe. It is of the interacting holographic dark energy with a bulk-holographic matter $\chi$.

Bose-Einstein Condensation of Dark Matter Axions [PDF]

open access: yes, 2009
We show that cold dark matter axions thermalize and form a Bose-Einstein condensate. We obtain the axion state in a homogeneous and isotropic universe, and derive the equations governing small axion perturbations.

Closed-form Expressions for Multiscatter Dark Matter Capture Rates

open access: yesThe Astrophysical Journal
Any astrophysical object can, in principle, serve as a probe of the interaction between dark matter (DM) and regular baryonic matter. This method is based on the potential observable consequences annihilations of captured DM have on the surface ...

Strongly-interacting ultralight millicharged particles

open access: yesPhysics Letters B, 2021
We consider the implications of an ultra-light fermionic dark matter candidate that carries baryon number. This naturally arises if dark matter has a small charge under standard model baryon number whilst having an asymmetry equal and opposite to that in

Cold dark matter with MOND scaling

open access: yesPhysics Letters B, 2010
We provide a holographic dual description of Milgrom's scaling associated with galactic rotation curves. Our argument is based on the recent entropic reinterpretation of Newton's laws of motion. We propose a duality between cold dark matter and modified Newtonian dynamics (MOND).

Cold Particle Dark Matter [PDF]

open access: yesSymmetry, 2021
Possible dark matter candidates in particle physics span a mass range extending over fifty orders of magnitude. In this review, we consider the range of masses from a few keV to a few hundred TeV, which is relevant for cold particle dark matter. We will consider models where dark matter arises as weakly coupled elementary fields and models where dark ...

Escape from TGF‐β‐induced senescence promotes aggressive hallmarks in epithelial hepatocellular carcinoma cells

open access: yesMolecular Oncology, EarlyView.
Chronic TGF‐β exposure drives epithelial HCC cells from a senescent state to a TGF‐β resistant mesenchymal phenotype. This transition is characterized by the loss of Smad3‐mediated signaling, escape from senescence, enhanced invasiveness and metastatic potential, and upregulation of key resistance modulators such as MARK1 and GRM8, ultimately promoting

Particle Physics Approach to Dark Matter

open access: yes, 2006
We review the main proposals of particle physics for the composition of the cold dark matter in the universe. Strong axion contribution to cold dark matter is not favored if the Peccei-Quinn field emerges with non-zero value at the end of inflation and ...
