Unified Models of Inflation and Quintessence
Andro Gonzalez, Tonatiuh Matos, Israel Quiros
We apply an extended version of the method developed in reference Int.J.Mod.Phys.D5(1996)71, to derive exact cosmological (flat) Friedmann-Robertson-Walker solutions in RS2 brane m…
A general relativistic approach to the Navarro-Frenk-White (NFW) galactic halos
Tonatiuh Matos, Dario Nunez, Roberto A Sussman
In order to study their interplay with large scale cosmic evolution and with relativistic effects, such as gravitational lenses, quintessence sources or gravitational waves, we con…
Scalar field "mini--MACHOs": a new explanation for galactic dark matter
Xavier Hernández, Tonatiuh Matos, Roberto A Sussman +1
We examine the possibility that galactic halos are collisionless ensembles of scalar field ``massive compact halo objects'' (MACHOs). Using mass constraints from MACHO microlensing…
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 spacetime associated with galactic dark matter halos
Tonatiuh Matos, Dario Nunez, Roberto A. Sussman
We show how an adequate post--Newtonian generalization can be obtained for Newtonian dark matter halos associated with an empiric density profile. Applying this approach to halos t…
