    • An Infinite Family of Magnetized Morgan-Morgan Relativistic Thin Disks 

      Gutiérrez-Piñeres A.C.; González G.A. (2012)
      Applying the Horský-Mitskievitch conjecture to the empty space solutions of Morgan and Morgan due to the gravitational field of a finite disk, we have obtained the corresponding solutions of the Einstein-Maxwell equations. ...

    • Conformastationary disk-haloes in Einstein–Maxwell gravity 

      Gutiérrez-Piñeres A.C. (Springer New York LLC, 2015)
      An exact solution of the Einstein–Maxwell field equations for a conformastationary metric with magnetized disk-haloes sources is worked out in full. The characterization of the nature of the energy momentum tensor of the ...

    • Exact galactic disk-haloes model in Einstein-Maxwell gravity 

      Gutiérrez-Piñeres A.C.; Capistrano A.J.S. (World Scientific Publishing Co. Pte. Ltd., 2018)
      An exact model in Einstein-Maxwell gravity describing a magnetized galactic disk-halo system is presented. The description of properties of the stationary metric and its source are discussed. All the expressions are presented ...

    • Motion of test particles in a magnetized conformastatic background 

      Gutiérrez-Piñeres A.C.; Capistrano A.J.S. (World Scientific Publishing Co. Pte. Ltd., 2018)
      A class of exact conformastatic solutions of the Einstein-Maxwell field equations is presented in which the gravitational and electromagnetic potentials are completely determined by a harmonic function only. The motion of ...

    • Newman–Janis Ansatz in conformastatic spacetimes 

      Gutiérrez-Piñeres A.C.; Quevedo H. (Springer New York LLC, 2016)
      The Newman–Janis Ansatz was used first to obtain the stationary Kerr metric from the static Schwarzschild metric. Many works have been devoted to investigate the physical significance of this Ansatz, but no definite answer ...

    • Variational thermodynamics of relativistic thin disks 

      Gutiérrez-Piñeres A.C.; Lopez-Monsalvo C.S.; Quevedo H. (Springer New York LLC, 2015)
      We present a relativistic model describing a thin disk system composed of two fluids. The system is surrounded by a halo in the presence of a non-trivial electromagnetic field. We show that the model is compatible with the ...
