Violating Weak Cosmic Censorship in AdS via Gedanken Experiment
Masaya Amo
The weak cosmic censorship conjecture (wCCC) might not be as robust as one would expect. We present a potential counterexample to the wCCC in a rotating three-dimensional anti-de S…
Entropy Bounds for Rotating AdS Black Holes
Masaya Amo, Antonia M. Frassino, Robie A. Hennigar
We propose novel thermodynamic inequalities that apply to stationary asymptotically Anti-de Sitter (AdS) black holes. These inequalities incorporate the thermodynamic volume and re…
Asymptotic behavior of null geodesics near future null infinity IV: Null-access theorem for generic asymptotically flat spacetime
Masaya Amo, Keisuke Izumi, Yoshimune Tomikawa +2
In our previous papers [arXiv:2106.03150, arXiv:2110.10917, arXiv:2208.00822], we analyzed the asymptotic behavior of future directed null geodesics near future null infinity and t…
A generalization of photon sphere based on escape/capture cone
Masaya Amo, Keisuke Izumi, Hirotaka Yoshino +2
In asymptotically flat spacetimes, bearing the null geodesics reaching the future null infinity in mind, we propose new concepts, the "dark horizons" as generalizations of the phot…
Asymptotic behavior of null geodesics near future null infinity. III. Photons towards inward directions
Masaya Amo, Keisuke Izumi, Yoshimune Tomikawa +2
A new sufficient condition for photons emitted near future null infinity to reach future null infinity is derived by studying null geodesics in the Bondi coordinates in asymptotica…
Asymptotic behavior of null geodesics near future null infinity II: curvatures, photon surface and dynamically transversely trapping surface
Masaya Amo, Tetsuya Shiromizu, Keisuke Izumi +2
Bearing in mind our previous study on asymptotic behavior of null geodesics near future null infinity, we analyze the behavior of geometrical quantities such as a certain extrinsic…
Asymptotic behavior of null geodesics near future null infinity: Significance of gravitational waves
Masaya Amo, Keisuke Izumi, Yoshimune Tomikawa +2
We investigate the behavior of null geodesics near future null infinity in asymptotically flat spacetimes. In particular, we focus on the asymptotic behavior of null geodesics that…
