摘要
本文推导了一种新的类史瓦西黑洞(Schwarzschild-like black hole, BH)解,描述了一个被暗物质(DM)晕包围的静态且渐近平坦的黑洞,其周围环境具有dehnen型密度分布。我们通过研究爱因斯坦引力中的曲率特性和能量条件来研究得到的黑洞的性质。此外,我们通过分析粒子的类时测地线以及黑洞的可观测性质,探索了嵌入具有dehnen型密度分布的DM光晕中的新型类史瓦西黑洞的特征。
Schwarzschild black hole in galaxies surrounded by a dark matter halo
In this paper, we derive a novel Schwarzschild-like black hole (BH) solution describing a static and asymptotically flat BH surrounded by a dark matter (DM) halo with a Dehnen-type density distribution in the surrounding environment. We investigate the properties of the obtained BH by studying the curvature properties and energy conditions in Einstein gravity. Furthermore, we explore the features of a novel Schwarzschild-like BH embedded in a DM halo with Dehnen-type density profile by analyzing the timelike geodesics of particles along with BH observable properties.
期刊介绍:
Journal of Cosmology and Astroparticle Physics (JCAP) encompasses theoretical, observational and experimental areas as well as computation and simulation. The journal covers the latest developments in the theory of all fundamental interactions and their cosmological implications (e.g. M-theory and cosmology, brane cosmology). JCAP''s coverage also includes topics such as formation, dynamics and clustering of galaxies, pre-galactic star formation, x-ray astronomy, radio astronomy, gravitational lensing, active galactic nuclei, intergalactic and interstellar matter.
