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…

Strong Cosmic Censorship for a Scalar Field in a Logarithmic-de Sitter Black Hole

Yiqian Chen, Qingyu Gan, Guangzhou Guo

It has been shown that the quasinormal modes of perturebated fields can be used to investigate the validity of strong cosmic censorship (SCC). Relevant issues for Reissner-Nordstro…

Strong Cosmic Censorship for a Scalar Field in a Born-Infeld-de Sitter Black Hole

Qingyu Gan, Guangzhou Guo, Peng Wang +1

It has been shown that the Strong Cosmic Censorship (SCC) can be violated by a scalar field in a near-extremal Reissner-Nordstrom-de Sitter black hole. In this paper, we investigat…

Temperature Dependence of In-plane Resistivity and Inverse Hall Angle in NLED Holographic Model

Qingyu Gan, Peng Wang, Haitang Yang

In the strange metal phase of the high- cuprates, it is challenging to explain the linear temperature dependence of the in-plane resistivity and the quadratic temperature de…
