“…The energy and momentum complex of Møller gives the possibility to make the calculations in any coordinate system [9]. To this end Virbhadra and his collaborators have considered many space-time models and have shown that several energy-momentum complexes give the same and acceptable results for a given space-time [10,11,12,13,14,15,16,17,18]. For example: Virbhadra [19], using the energy and momentum complexes of Einstein, Landau-Lifshitz, Papapetrou and Weinberg's for a general non-static spherically symmetric metric of the Kerr-Schild class and showed that all of these energy-momentum formulations give the same energy distribution as in Penrose energy-momentum formulation.…”

Abstract. Using the Bergmann-Thomson energy momentum complex and its teleparallel gravity version, we obtain the energy and momentum of the universe in viscous Kasner-type cosmological models. The energy and momentum components (due to matter plus field) are found to be zero and this agree with a previous work of Rosen and Johri et al. who investigated the problem of the energy in Friedmann-RobertsonWalker universe. The result that the total energy and momentum components of the universe in these models is zero supports the viewpoint of Tryon. Rosen found that the energy of the Friedmann-Robertson-Walker space-time is zero, which agrees with the studies of Tryon.

“…This is twice the effective mass computed by Chamorro and Virbhadra [15] who utilized the Einstein's and Landau-Lifshitz's energy-momentum complexes 4 . Additionally, the power output, as given by (28), of the Bonnor-Vaidya spacetime is…”

The effective gravitational mass as well as the energy and momentum distributions of a radiating charged particle in Einstein's universe are evaluated. The Møller's energy-momentum complex is employed for this computation. The spacetime under study is a generalization of Bonnor and Vaidya spacetime in the sense that the metric is described in the cosmological background of Einstein's universe in lieu of the flat background. Several spacetimes are limiting cases of the one considered here. Particularly for the Reissner-Nordström black hole background, our results are exactly the same with those derived by Cohen and Gautreau using Whittaker's theorem and by Cohen and de Felice using Komar's mass. Furthermore, the power output for the spacetime under consideration is obtained.

“…This metric looks like a radiating charged Vaidya black, namely the Bonnor-Vaidya black hole [37], with the dynamical charge Q(u) = √ N r (u), see also [46] for the radiating dyon solution. This result can be interpreted as the positive contribution of the characteristic feature of the surrounding radiation field to the effective charge term of the Vaidya black hole with the 1 r 2 gravitational contribution.…”

In the present work, we study the general surrounded Vaidya solution by the various cosmological fields and its nature describing the possibility of the formation of naked singularities or black holes. Motivated by the fact that real astrophysical black holes as non-stationary and nonisolated objects are living in non-empty backgrounds, we focus on the black hole subclasses of this general solution describing a dynamical evaporating-accreting black holes in the dynamical cosmological backgrounds of dust, radiation, quintessence, cosmological constant-like and phantom fields, the so called "surrounded Vaidya black hole". Then, we analyze the timelike geodesics associated with the obtained surrounded black holes and we find that some new correction terms arise relative to the case of Schwarzschild black hole. Also, we address some of the subclasses of the obtained surrounded black hole solution for both dynamical and stationary limits. Moreover, we classify the obtained solutions according to their behaviors under imposing the positive energy condition and discuss how this condition imposes some severe and important restrictions on the black hole and its background field dynamics.
