清喉咙的声音:来自在虫洞几何中运行的黑洞的引力波

The Sound of Clearing the Throat: Gravitational Waves from a Black Hole Orbiting in a Wormhole Geometry

James B. Dent, William E. Gabella, Kelly Holley-Bockelmann, Thomas W. Kephart

摘要:

目前的地面引力波探测器被调整为捕捉致密物体的碰撞,如恒星起源的黑洞和中子星;迄今为止已经公布了20多起此类事件。然而,从理论上讲,可能存在更奇特的紧凑物体,它们的碰撞也应该产生大量的引力波。在本文中,我们模拟了恒星质量的黑洞进入稳定的,非旋转的,可穿越的虫洞的螺旋,并发现了一个特征波形-反啁啾和/或爆发-作为黑洞出现,即,外旋进入我们的宇宙区域这种新颖的波形特征可能有助于在未来的引力波数据中搜索虫洞,或者用于限制我们宇宙中可能的虫洞几何形状。

英文摘要:

Current ground-based gravitational wave detectors are tuned to capture the collision of compact objects such as stellar origin black holes and neutron stars; over 20 such events have been published to date. Theoretically, however, more exotic compact objects may exist, collisions of which should also generate copious gravitational waves. In this paper, we model the inspiral of a stellar mass black hole into a stable, non-spinning, traversable wormhole, and find a characteristic waveform -- an anti-chirp and/or burst -- as the black hole emerges, i.e., outspirals, into our region of the Universe. This novel waveform signature may be useful in searches for wormholes in future gravitational wave data or used to constrain possible wormhole geometries in our Universe.
