Casadio-Fabbri-Mazzacurati黑弦与膜世界诱导类星体亮度修正
Casadio-Fabbri-Mazzacurati Black Strings and Braneworld-induced Quasars Luminosity Corrections
摘要：
本文旨在揭示膜世界范式中对黑弦弯曲视界的修正，及其严重的物理后果，并提供在天体物理学中的后续应用。我们对膜上黑洞的分析与史瓦西情形不同，在史瓦西情形中，黑弦对大尺度扰动是不稳定的。研究了膜世界效应引起的黑弦视界改正的可测性及其在类星体光度变化中的应用。我们深入研究的情况下，其中两个解决方案的爱因斯坦方程提出的Casadio，Fabbri和Mazzacurati，关于黑洞度量提出后牛顿参数测量膜。在这种情况下，通过适当地选择排除膜上霍金辐射的后牛顿参数，就有可能纯粹分析类星体光度的膜世界修正变化：类星体光度的变化是由纯膜世界效应提供的，因为膜上的霍金辐射被抑制了。
英文摘要：
This paper aims to evince the corrections on the black string warped horizon in the braneworld paradigm, and their drastic physical consequences, as well as to provide subsequent applications in astrophysics. Our analysis concerning black holes on the brane departs from the Schwarzschild case, where the black string is unstable to large-scale perturbation. The cognizable measurability of the black string horizon corrections due to braneworld effects is investigated, as well as their applications in the variation of quasars luminosity. We delve into the case wherein two solutions of Einstein's equations proposed by Casadio, Fabbri, and Mazzacurati, regarding black hole metrics presenting a post-Newtonian parameter measured on the brane. In this scenario, it is possible to analyze purely the braneworld corrected variation in quasars luminosity, by an appropriate choice of the post-Newtonian parameter that precludes Hawking radiation on the brane: the variation in quasars luminosity is uniquely provided by pure braneworld effects, as the Hawking radiation on the brane is suppressed.
