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…
Black Hole Shadow with Soft Hair
Feng-Li Lin, Avani Patel, Hung-Yi Pu
Light bending by the strong gravity around the black hole will form the so-called black hole shadow, the shape of which can shed light on the structure of the near-horizon geometry…
Constraints on black-hole charges with the 2017 EHT observations of M87*
Prashant Kocherlakota, Luciano Rezzolla, Heino Falcke +234
Our understanding of strong gravity near supermassive compact objects has recently improved thanks to the measurements made by the Event Horizon Telescope (EHT). We use here the M8…
Observational and Experimental Gravity
Angela D. V. Di Virgilio, Wei-Tou Ni, Sperello di Serego Alighieri +2
We indicate the progress of experimental gravity, present an outlook in this field, and summarise the Observational/Experimental Parallel Session together with a related plenary ta…
On Spin Dependence of Relativistic Acoustic Geometry
Hung-Yi Pu, Ishita Maiti, Tapas Kumar Das +1
This work makes the first ever attempt to understand the influence of the black hole background space-time in determining the fundamental properties of the embedded relativistic ac…
