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…
