TY - JOUR ID - 58062 AU - Churilova, Mariia - Konoplya, Roman - Stuchlík, Zdeněk - Zhidenko, A. PY - 2021 TI - Wormholes without exotic matter: Quasinormal modes, echoes and shadows JF - Journal of Cosmology and Astroparticle Physics VL - 10 IS - October SP - "010-1"-"010-17" EP - "010-1"-"010-17" SN - 14757516 KW - Wormholes;gravitational waves;theory;gravity UR - https://iopscience.iop.org/article/10.1088/1475-7516/2021/10/010 N2 - An analytical solution representing traversable asymptotically flat and symmetric wormholes was obtained without adding exotic matter in two different theories independently: in the Einstein-Maxwell-Dirac theory and in the second Randall-Sundrum brane-world model. Further, a smooth normalizable asymmetric wormhole solution has been recently obtained numerically in the Einstein-Maxwell-Dirac theory. Using the time-domain integration method we study quasinormal ringing of all these wormholes with emphasis to the regime of mimicking the near extremal Reissner-Nordstrom black holes, which is characterised by echoes. In addition, we calculate radius of shadows cast by these wormholes. ER -
