TY - JOUR ID - 58602 AU - Stuchlík, Zdeněk - Vrba, Jaroslav PY - 2021 TI - Epicyclic Oscillations around Simpson-Visser Regular Black Holes and Wormholes JF - Universe VL - 7 IS - 8 SP - "279-1"-"279-15" EP - "279-1"-"279-15" SN - 22181997 KW - wormhole KW - quasi-periodic oscillation KW - supermassive quasars UR - https://www.mdpi.com/2218-1997/7/8/279 N2 - We study epicyclic oscillatory motion along circular geodesics of the Simpson-Visser metageometry describing in a unique way regular black-bounce black holes and reflection-symmetric wormholes by using a length parameter l. We give the frequencies of the orbital and epicyclic motion in a Keplerian disc with inner edge at the innermost circular geodesic located above the black hole outer horizon or on the our side of the wormhole. We use these frequencies in the epicyclic resonance version of the so-called geodesic models of high-frequency quasi-periodic oscillations (HF QPOs) observed in microquasars and around supermassive black holes in active galactic nuclei to test the ability of this meta-geometry to improve the fitting of HF QPOs observational data from the surrounding of supermassive black holes. We demonstrate that this is really possible for wormholes with sufficiently high length parameter l. ER -
