We derive the hyperbolic orbit of binary black holes with electric and magnetic charges. In
the low-velocity and weak-field regime, by using the Newtonian method, we calculate the …

The recent stochastic signal observed jointly by NANOGrav, parkes pulsar timing array,
European pulsar timing array, and Chinese pulsar timing array can be accounted for by …

We consider the two-body dynamical capture of black holes carrying U (1) charge which can
not only correspond to electric or magnetic charge but also have other physical …

A bstract We present current direct and astrophysical limits on the cosmological abundance
of black holes with extremal magnetic charge. Such black holes do not Hawking radiate …

We analyze the formation and evolution of the event horizon of a black hole binary merger
when the black holes are charged. We find that the presence of charge influences the …

In this manuscript, we investigate the electromagnetic radiation of a binary system of
electrically charged black holes. Using the results of previous works, we compute the …

The stochastic signal detected by the NANOGrav, PPTA, EPTA, and CPTA collaborations
can be attributed to gravitational waves induced by the primordial curvature perturbations …

The common-spectrum process, characterized by the Hellings–Downs angular correlation
and observed by pulsar timing array collaborations, such as NANOGrav, PPTA, EPTA, and …

The stochastic signal observed by collaborations such as NANOGrav, PPTA, EPTA+ InPTA,
and CPTA may originate from gravitational waves induced by primordial curvature …

Black hole binary systems can form and evolve in the inner region of a galaxy, where usually
a supermassive black hole is located. These three objects naturally form a triple system …
