Dark matter may be invisible gravitational ghost images and not the real matter imagined

According to the polar effect in the hyperspherical universe, we realize that “Dark matter” may be invisible gravitational ghost images originating from the matter around the poles and not the real na...
The inverse-Compton ghost HDF 130 and the giant radio galaxy 6C 0905+3955: matching an analytic model for double radio source evolution
galaxies: individual: RGJ123617/HDF130, 6C0905+3955 – galaxies: evolution – galaxies: jets – radio continuum: galaxies – X-rays: galaxies.
2011/9/28
We present new GMRT observations of HDF 130, an inverse-Compton (IC) ghost of a giant radio source that is no longer being powered by jets. We compare the properties of HDF 130 with the new and import...

We study a phenomenological dark energy model which is rooted in the Veneziano ghost of QCD. In this dark energy model, the energy density of dark energy is proportional to Hubble parameter and the pr...

We use a new set of cold dark matter simulations of the local universe to investigate the distribution of fossils of primordial dwarf galaxies within, and around the Milky Way.

It has been suggested that the dark energy that explains the observed accelerating expansion of the universe may arise due to the contribution to the vacuum energy of the QCD ghost in a time-dependent...
Ghost anomalous dimension in asymptotically safe quantum gravity

2010/3/22
We compute the ghost anomalous dimension within the asymptotic-safety scenario for quantum gravity. For a class of covariant gauge fixings and using a functional RG scheme, the anomalous dimension $\e...
We revisit ghost dark matter, the possibility that ghost condensation may serve as an alternative to dark matter. In particular, we investigate the Friedmann-Robertson-Walker (FRW) background evolutio...
