Photon Ring and Observational Appearance of a Hairy Black Hole
Qingyu Gan, Peng Wang, Houwen Wu +1
Recently, the image of a Schwarzschild black hole with an accretion disk has been revisited, and it showed that the "photon ring", defined as highly bent light rays that intersect…
Photon Spheres and Spherical Accretion Image of a Hairy Black Hole
Qingyu Gan, Peng Wang, Houwen Wu +1
In this paper, we first consider null geodesics of a class of charged, spherical and asymptotically flat hairy black holes in an Einstein-Maxwell-scalar theory with a non-minimal c…
Scalarized Einstein-Maxwell-scalar Black Holes in Anti-de Sitter Spacetime
Guangzhou Guo, Peng Wang, Houwen Wu +1
In this paper, we study spontaneous scalarization of asymptotically anti-de Sitter charged black holes in the Einstein-Maxwell-scalar model with a non-minimal coupling between the…
Derive Lovelock Gravity from String Theory in Cosmological Background
Peng Wang, Houwen Wu, Haitang Yang +1
It was proved more than three decades ago, that the first order correction of string effective theory could be written as the Gauss-Bonnet term, which is the quadratic term of…
Scalarized Einstein-Born-Infeld-scalar Black Holes
Peng Wang, Houwen Wu, Haitang Yang
The phenomenon of spontaneous scalarization of Reissner-Nordström (RN) black holes has recently been found in an Einstein-Maxwell-scalar (EMS) model due to a non-minimal coupling b…
Extended Phase Space Thermodynamics for Black Holes in a Cavity
Peng Wang, Houwen Wu, Haitang Yang +1
In this paper, we extend the phase space of black holes enclosed by a spherical cavity of radius to include as a thermodynamic volume. The thermodyna…
