Shadow of rotating black holes with consistent thermodynamics
Che-Yu Chen, Chiang-Mei Chen, Nobuyoshi Ohta
Quantum effects in general induce scale dependence in the coupling constants. We explore this possibility in gravity, with a scale-dependent Newton coupling. When applied to Kerr b…

Bianchi-I cosmology with scale dependent and in asymptotically safe gravity
Chiang-Mei Chen, Akihiro Ishibashi, Rituparna Mandal +1
We study anisotropic Bianchi-I cosmology, incorporating quantum gravitational corrections into the Einstein equation through the scale-dependent Newton coupling and cosmological te…

Singularity resolution and regular black hole formation in gravitational collapse in asymptotically safe gravity
Tomohiro Harada, Chiang-Mei Chen, Rituparna Mandal
We adopt an effective action inspired by asymptotically safe gravity, in which the effective gravitational constant is parametrized as …
