摘要

在本研究中,我们研究了非交换黑洞解决方案的特征。首先,我们计算了系统的热力学性质,包括熵、热容量和霍金辐射。对于霍金辐射,我们采用了两种不同的方法:表面引力法和拓扑法。此外,我们还在此背景下研究了辐射率和残余质量。值得注意的是,黑洞在蒸发过程中达到最终状态后的寿命,可以通过灰体因子进行解析。我们估算了特定初始和最终质量配置的寿命。此外,我们还使用六阶 WKB 方法分析了张量准正常模式。最后,我们研究了弱偏转和强偏转极限下的偏转角,即引力透镜。

Effects of non-commutative geometry on black hole properties

In this study, we investigate the signatures of a non-commutative black hole solution. Initially, we calculate the thermodynamic properties of the system, including entropy, heat capacity, and Hawking radiation. For the latter quantity, we employ two distinct methods: surface gravity and the topological approach. Additionally, we examine the emission rate and remnant mass within this context. Remarkably, the lifetime of the black hole, after reaching its final state due to the evaporation process, is expressed analytically up to a grey-body factor. We estimate the lifetime for specific initial and final mass configurations. Also, we analyze the tensorial quasinormal modes using the 6th-order WKB method. Finally, we study the deflection angle, i.e., gravitational lensing, in both the weak and strong deflection limits.
