Abstract

The main objective of the study is to develop a model that modifies the traditional Hawking temperature by considering the influence of internal variables such as radius, mass, electric charge, angular momentum, and cosmological constant. The research method involves mathematical analysis and computational modeling based on the modified Hawking temperature equation. The results show that the modified Hawking temperature produces non-linear corrections that show the interaction between black holes and the quantum structure of spacetime. graphical representations visualize the variation of Hawking temperature with changes in area, electric charge, angular momentum, and cosmological parameters. The implications of the research extend to the understanding of the thermal properties of black holes in the context of gravitational and quantum theories. The research identifies gaps in the knowledge of the effects of cosmological parameters on black hole thermodynamics and introduces Hawking temperature modifications that have not been mapped in detail before. The study concludes that the Hawking temperature modification provides a strong foundation for further research in black hole physics, particularly in the effect of physical and cosmological parameters on the thermal properties of black holes.

Abstract

This study analyzes the effect of multipole values (\( \ell\)) on the distribution of gravitational or electromagnetic fields in black holes, using the Regge-Wheeler potential approach. Various masses (5, 10, 20, 50) and varying \( \ell\) values are analyzed to explore the impact of multipole on space-time geometry. The results show that increasing the value of \( \ell\) reduces the values of \( r_{\text{positive}}\) and \( r_{\text{negative}}\), which indicates the field distribution becomes more focused at higher multipole values. The sensitivity to changes in the \( \ell\) value is especially noticeable in the colinear \( \ell\) interval between 5 to 17, where small changes in the \( \ell\) value result in large changes in the \( r\) value. In the framework of black hole theory, two solutions of the quadratic equation \( \ell = \frac{-1 \pm\sqrt{13}}{2}\) yield two values \( \ell_+\) and \( \ell_-\), which affect the distribution of the gravitational field. Logarithmic analysis of the \( r \) value reveals variations in the field distribution in the multipole range, and shows a strong dependence on the black hole mass, with more significant changes at small masses. This study provides a deeper understanding of the dependence of the field distribution on multipole and opens up opportunities for further research into the complexity of multipolar interactions in black hole theory.

Abstract

This research delves into the approximate relationship between the energy function (E) and the Hubble function (H) within cosmological. Utilizing the Friedmann equation, it establishes a link between the universe's scale factor and the Hubble function. Through Taylor series approximation, the study derives an approximation of the energy function, under specific assumptions and approximations. Asymptotic analysis investigates the behavior of variables y and s, shedding light on function limits and behaviors. The study incorporates an interactive 3D scatter plot visualization to elucidate the relationship between cosmological parameters and physical systems, aiding in a comprehensive understanding of dynamics. Practical recommendations emphasize increasing data points for accuracy and validating with observational data, while theoretical suggestions advocate exploring higher-order terms and considering additional physical factors.
