The Scalar Fields with Negative Kinetic Energy, Dark Matter and Dark Energy

General Relativity and Gravitation, 2004
In the paper it is shown that the model with scalar ghost-field and other components of matter can explain the two main facts from modern cosmology that is the dark matter and accelerating expansion of the Universe. In such models the probability exists to obtain the representation of an inhomogeneous structure of a matter distribution forming in a ...

Structure Formation with Scalar Field Dark Matter

AIP Conference Proceedings, 2010
In this work we calculate the different ingredients needed to obtain the matter density profile of the large‐scale structure we observe now a days in a qualitative way. The key difference of the work lays on the fact that we study the formation of structure in the Universe assuming that dark matter can be described by a scalar field (SF) Φ with a ...

The massless scalar field as an alternative to dark matter

Astronomical & Astrophysical Transactions, 1997
Abstract It is shown that if the scalar gravitational field in the generalized scalar—tensor theory of gravitation is taken into account, the cosmological requirement for the existence of dark matter is less strong.
