Investigating the Generalized Uncertainty Principle Effects on Hawking Radiation in Rotating Linear Dilaton Black Holes

The impact of the Generalized Uncertainty Principle (GUP) on Hawking particle emission in a rotating linear dilaton black hole (RLDBH) spacetime is examined in this thesis. The concerned study presents a thermal emission model for black holes (BHs) that incorporates the influence of gravitational lens particles through GUP during the quantum tunneling process. The findings suggest that with GUP support, the temperature of Hawking radiation decreases as GUP parameters increase and rises with an increasing BH mass. The thesis also delves into the repercussions of these discoveries on the information loss paradox and adjusted entropy, while also exploring the potential utilization of astrophysical data to confirm GUP effects. In conclusion, our work underscores the significant role of GUP in the thermal emission of non-asymptotically flat (NAF), stationary BHs and its capacity to shed light on the intricate relationship between astrophysics and quantum gravity.

The Effect of Quark-antiquark Confinement on the Deflection Angle by the NED Black Hole

In this study, we explore the influence of quark-antiquark confinement on the deflection angle within the framework of nonlinear electrodynamic (NED) black holes. To achieve this, we establish the appropriate optical spacetime metric and subsequently determine the Gaussian optical curvature. Utilizing the Gauss-Bonnet theorem, we investigate the impact of quark-antiquark confinement on the deflection angle exhibited by NED black holes. Additionally, we delve into the effects of a cold non-magnetized plasma medium and also axion-plasmon on gravitational lensing. Our findings highlight the significance of the axion-plasmon effect on the optical properties of NED black holes, particularly its influence on gravitational lensing. This exploration is particularly relevant in the context of the axion's potential role as a dark matter candidate. The multifaceted interplay between quark-antiquark confinement, nonlinear electrodynamics, and plasma dynamics provides a nuanced understanding of gravitational lensing phenomena. These insights contribute to ongoing research in dark matter studies and offer avenues for further theoretical and observational investigations in astrophysics.
