新张量-矢量-标量理论中的装扮黑洞

Dressed black holes in the new tensor-vector-scalar theory

Reginald Christian Bernardo, Che-Yu Chen

摘要:

黑洞是引力在其全盛时期的化身,可以说是我们揭开引力神秘面纱的最佳目标。考虑到黑洞在引力波天文学中扮演的重要角色,一个理论必须拥有与广义相对论对应物只有可测量偏差的黑洞解。在本文中,我们提出了黑洞在张量-矢量-标量表示的相对论修改牛顿动力学。我们发现,该理论允许史瓦西和近史瓦西黑洞作为解决方案,而非平凡的标量场和矢量场一般在事件视界发散。这是否是一种物理病理学对这些解决方案以及扩展后的模型构成了挑战。然而,即使是这样,当黑洞毛发消失时,这种病理学也可以克服。

英文摘要:

As incarnations of gravity in its prime, black holes are arguably the best target for us to demystify gravity. Keeping in mind the prominent role black holes play in gravitational wave astronomy, it becomes a must for a theory to possess black hole solutions with only measurable departures from their general relativity counterparts. In this paper, we present black holes in a tensor-vector-scalar representation of relativistic modified Newtonian dynamics. We find that the theory allows Schwarzschild and nearly-Schwarzschild black holes as solutions, while the nontrivial scalar and vector fields generally diverge at the event horizon. Whether this is a physical pathology or not poses a challenge for these solutions, and by extension, the model. However, even if it is, this pathology could be overcome when the black hole hair vanishes.
