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…
An upper limit on the mass of galactic halo dark matter particles through the use of the Holographic principle
X. Hernandez, L. G. Cabral-Rosetti, R. Sussman
This paper was withdrawn by the authors due to serious flaws in the physics that render the results meaningless.
Using Entropy to Discriminate Annihilation Channels in Neutralinos Making up Galactic Halos
Luis G. Cabral-Rosetti, Xavier Hernández, Roberto A. Sussman
Applying the microcanonical definition of entropy to a weakly interacting and self--gravitating neutralino gas, we evaluate the change in the local entropy per particle of this gas…
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…
Adiabatic models of the cosmological radiative era
Roberto A. Sussman, Mustapha Ishak
We consider a generalization of the Lemaitre-Tolman-Bondi (LTB) solutions by keeping the LTB metric but replacing its dust matter source by an imperfect fluid with anisotropic pres…
