Stellar polytropes and Navarro--Frenk--White dark matter halos: a connection to Tsallis entropy
Luis G. Cabral-Rosetti, Tonatiuh Matos, Darío Núñez +2
We present an alternative for the description of galactic halos based on Tsallis' non--extensive entropy formalism; on this scheme, halos are stellar polytropes characterized by th…
The general relativistic geometry of the Navarro-Frenk-White model
Tonatiuh Matos, Dario Nunez
We derive the space time geometry associated with the Navarro Frenk White dark matter galactic halo model. We discuss several properties of such a spacetime, with particular attent…
Hydrodynamical description of Galactic Dark Matter
Luis G. Cabral-Rosetti, Dario Nunez, Roberto A. Sussman +1
We consider simple hydrodynamical models of galactic dark matter in which the galactic halo is a self-gravitating and self-interacting gas that dominates the dynamics of the galaxy…
Scalar Field Dark Matter and Galaxy Formation
Miguel Alcubierre, F. Siddhartha Guzman, Tonatiuh Matos +3
We present a general description of the scalar field dark matter (SFDM) hypothesis in the cosmological context. The scenario of structure formation under such a hypothesis is based…
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…
