Recently, Vagnozzi and Visinelli's work [Phys. Rev. D 100, 024020 (2020)] reveals that M87*'s shadow establishes an upper limit of AU, where is the AdS cur…
Consistent mass formulas for the four-dimensional dyonic NUT-charged spacetimes
Di Wu, Shuang-Qing Wu
In our previous work, a novel idea that the NUT charge can be thought of as a thermodynamical multi-hair has been advocated to describe perfectly the thermodynamical character of t…
