The Science of the Einstein Telescope
Adrian Abac, Raul Abramo, Simone Albanesi +485
Einstein Telescope (ET) is the European project for a gravitational-wave (GW) observatory of third-generation. In this paper we present a comprehensive discussion of its science ob…
On particle dynamics near the singularity inside the Schwarzschild black hole and T-spheres
A. Radosz, A. V. Toporensky, O. B. Zaslavskii
The problem of the speed of the objects inside the Schwarzschild black hole is considered. The general result is that the value of the relative speed of the objects following their…
The Doppler shift in a Schwarzschild spacetime
A. Radosz, A. T. Augousti, K. Ostasiewicz
We demonstrate that in the case of Schwarzschild spacetime the Doppler shift is partially factorized into terms representing relativistic, kinematical and the gravitational contrib…
Doppler effect in Schwarzschild geometry
A. Radosz, A. T. Augousti, K. Ostasiewicz
The Doppler shift considered in general relativity involves mixed contributions of distinct, gravitational and kinematical origins and for most metrics or trajectories it takes a c…
