RELATIVISTIC MASS OF SPINNING BLACK HOLES IN AGN

Aims: To calculate the relativistic mass of spinning black holes in AGN on the basis of model Capture22.formulated with the help of the model for estimation of mass of black holes M=rv2/G [1,2] and the model for variation of Universal constant (G) with spinning velocity of black holes Capture23. in the strong gravitational field as proposed by Mahto et al. [3].

Study Design: The data for the mass of spinning black holes in AGN in ranging from 106 to 109.5 solar masses [2] and spinning velocity from 50 to 100% of velocity of light [4] and radius of event horizon corresponding to the masses from 1.475x109m to 1.475x1012m [5] have been used to calculate the required results. This work is a supplement part of the research paper entitled: Relativistic Mass of Spinning Black Holes in XRBs published in Research Square (preprint, 2023) and communicated to Astrophysics and Space Science (2022).

Place and Duration of Study: Department of Physics, Marwari College under TMBU Bhagalpur from January 2021 to September 2023 and Bhagalpur College of Engineering, Bhagalpur under DST, Govt. of Bihar, India from October, 2023 to January 2023.

Methodology: The present work is completely theoretical based on specific model and data analysis. The work is completed at the residence of author as well as personal chamber of the working institution.

Results: The work gives the calculation for the relativistic mass of spinning black holes in the case of AGN to give the confirmation of the validity of special relativity.

Conclusion: The present work gives the validity in support of theory of relativity in AGN as well as proposed model Capture24.and can be frequently used for the estimation of the relativistic mass of AGN SBHs.
