  • Constant curvature f(R) gravity minimally coupled with Yang-Mills field 
    Mazharimousavi, S. Habib; Halilsoy, Mustafa; Tahamtan, Tayebeh (European Physical Journal C, Springer, 2011)
    We consider the particular class of f(R) gravities minimally coupled with Yang - Mills (YM) field in which the Ricci scalar =R_{0}= constant in all dimensions d\geq4. Even in this restricted class the spacetime has unlimited ...
  • Regular charged black hole construction in 2+1 -dimensions 
    Mazharimousavi, S. Habib; Halilsoy, Mustafa; Tahamtan, Tayebeh (Physics Letters A, Elsevier, 2012)
    It is well-known that unlike its chargeless version the charged Banados-Teitelboim-Zanelli (BTZ) black hole solution in 2+1- dimensional spacetime is singular. We construct a charged, regular extension of the BTZ black ...
  • Solutions for f(R) gravity coupled with electromagnetic field 
    Mazharimousavi, S. Habib; Halilsoy, Mustafa; Tahamtan, Tayebeh (European Physical Journal C, Springer, 2012)
    In the presence of external, linear / nonlinear electromagnetic fields we integrate f(R) \sim R+2{\alpha}\surd(R+const.) gravity equations. In contrast to their Einsteinian cousins the obtained black holes are non-asymptotically ...
  • Stable Magnetic Universes Revisited 
    Tahamtan, Tayebeh; Halilsoy, Mustafa (Astrophysics and Space Science, Springer, 2013)
    A regular class of static, cylindrically symmetric pure magnetic field metrics is rederived in a different metric ansatz in all dimensions. Radial, time dependent perturbations show that for dimensions d>3 such spacetimes ...
