Answer to the Comment about the Letter entitled ``Scalar fields as dark matter in spiral galaxies''
F. S. Guzman, T. Matos
In this manuscript the authors present a detailed answer to the comment in order to avoid misunderstandings in the future.
Geometric Conditions on the Type of Matter Determining the Flat Behavior of the Rotational Curves in Galaxies
Tonatiuh Matos, Dario Nunez, F. Siddhartha Guzman +1
In an arbitrary axisymmetric stationary spacetime, we determine the expression for the tangential velocity of test objects following a circular stable geodesic motion in the equato…
Quintessence-like Dark Matter in Spiral Galaxies
F. Siddhartha Guzman, Tonatiuh Matos, Dario Nunez +1
Through the geodesic analysis of a static and axially symmetric space time, we present conditions on the state equation of an isotropic perfect fluid , when it is considered…
Quintessence at Galactic Level?
T. Matos, F. S. Guzman
Recently it has been proposed that the main contributor to the dark energy of the Universe is a dynamical, slow evolving, spatially inhomogeneous scalar field called quintessence.…
