Imprints of core/cusp dark matter distributions on black hole signatures in galaxies
Hassan Hassanabadi, Che-Yu Chen, Soroush Zare +1
In galactic environments, a host dark matter (DM) halo can imprint weak but coherent corrections on black hole (BH) strong-field observables. We construct an exact family of static…
Shadow signatures and energy accumulation in Lorentzian-Euclidean black holes
Emmanuele Battista, Salvatore Capozziello, Che-Yu Chen
The Lorentzian-Euclidean black hole has been recently introduced as a geodesically complete spacetime featuring a signature shift at the event horizon where causal geodesics are pr…
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…
Observational features of reflection asymmetric black holes
Che-Yu Chen, Hung-Yi Pu
The Kerr spacetime is symmetric with respect to a well-defined equatorial plane. When testing the equatorial reflection symmetry of an isolated black hole, one is at the same time…
Testing black hole equatorial reflection symmetry using Sgr A* shadow images
Che-Yu Chen
The recently released images of the supermassive black holes in the M87 galaxy and the galaxy of our own make probing black hole spacetimes and testing general relativity (GR) poss…
From Bubbles and Filaments to Cores and Disks: Gas Gathering and Growth of Structure Leading to the Formation of Stellar Systems
Jaime E. Pineda, Doris Arzoumanian, Philippe André +8
The study of the development of structures on multiple scales in the cold interstellar medium has experienced rapid expansion in the past decade, on both the observational and the…
Rotating black holes without symmetry and their shadow images
Che-Yu Chen
The recent detection of gravitational waves from black hole coalescences and the first image of the black hole shadow enhance the possibilities of testing gravitational theories in…
