Phantom黑洞及其可观测效应的研究

Black hole and dark energy are the most active fields of research in astrophysics and gravity at present. It is a very important and interesting new topic to study the interaction effects between black hole and dark energy. In this project, we apply ourselves to studying the phantom black holes and their observable effects. Adopting some numerical or analytical methods, we will look for phantom black hole solutions in a various of theories of gravity. And then, we will investigate the spacetime structure and thermodynamic properties, Hawking radiation of these phantom black holes and study the dynamical evolution of perturbational fields in the background of such black holes. Moreover, we will try to find out the general law for physics of the phantom black hole and to promote a deep understanding the inherent physics of the model of phantom field. Furthermore, we will investigate the observable effects of various kinds of phantom black holes and find out some constraint on phantom field from black hole physics，which could provide some theoretical evidence to identify and constrain the phantom hair carried by black holes. The study in this project will help us in making a new recognition of and a deep understanding of the phantom field, which will promote a further comprehension of some fundamental theoretical problems in black hole physics, dark energy and gravity.

黑洞和暗能量是当今引力理论和天体物理学中最为活跃的研究领域。研究黑洞和暗能量之间的相互影响是其中一个非常有趣且极为重要的新课题。本项目致力于phantom黑洞及其可观测效应的研究。通过采用解析方法和数值计算，我们将对各种引力理论中phantom黑洞新解的形式及其时空结构、热力学性质、霍金辐射以及微扰场在这类黑洞背景中的动力学演化特征进行系统深入的研究，进而找出phantom黑洞物理的普适规律，同时深化对phantom模型物理内涵的理解。然后进一步研究各类phantom黑洞时空中的可观测效应，从黑洞物理的角度找出对phantom场的一些限制条件，从而为鉴别和限定黑洞的phantom毛发提供理论依据。本项目的研究结果有助于人们对phantom场进行重新认识和了解，同时加深对黑洞物理、暗能量物理以及引力理论中一些基本问题的理解。

黑洞和暗能量是当今引力理论和天体物理学中最为活跃的研究领域。研究黑洞和暗能量之间的相互影响是其中一个非常有趣且极为重要的新课题。在本项目中我们主要研究了phantom黑洞及其可观测效应。我们得到了两个phantom缓慢旋转黑洞的解，并研究了phantom场对黑洞霍金温度、黑洞熵以及霍金辐射的影响，同时也研究了phantom参数对星体绕黑洞旋转的周期、黑洞阴影等天文可观测量的影响。利用准周期振荡模型和天文上对GRO J1655-40相关观测数据，对缓慢旋转、规则的phantom黑洞的时空参数进行了限定，从黑洞物理的角度对phantom场进行了初步检测和限定。此外，我们还在黑洞的强引力透镜、黑洞背景下时空曲率与物质场导数耦合理论模型以及黑洞时空中粒子的混沌运动等方面做了一些研究工作。
