“…Understanding how seed black holes grow into IMBHs and SMBHs, has important implications for the duty-cycle of AGN, galaxy evolution, and gravitational wave astronomy. Therefore, a large series of numerical simulations are undertaken by [15,16], with the goal to trace an evolution of the mass assembly history of 377 accreting SMBH seeds in AGNs to the present time and examine the observable signatures today.…”

“…The MTBH is the extension of the PBHM and rather completes it by exploring the most important processes of rearrangement of vacuum state and a spontaneous breaking of gauge symmetry in gravity, and thereof for that of rearrangement of vacuum state, at huge energies (see e.g. [15,16] and references therein). Replacing a central singularity by the infrastructures inside event horizon, subject to certain rules, this theory makes room for the growth and merging properties of accreting black hole seeds.…”

Recently observed rare mighty X-ray coherent pulsations coming from M82X-2 impose a significant challenge in breaking the Eddington limit. Alternative approach to circumvent the obstacles was studied in [1,2] by addressing the M82X-2 as a spinning intermediate mass black hole, resided in final stage of growth. This approach employs the microscopic theory of black hole (MTBH), which explores a spontaneous breaking of gravitation gauge symmetry at huge energies. The preceding developments of this theory are proved to be quite fruitful for addressing the growth and merging phenomena of the black hole seeds. It explains as well the origin of ZeV-neutrinos, which are of vital interest for the source of ultra-high energy particles. In the present work, we further expose the assertions made in previous model via a computation of essential astrophysical corrections introduced by the rotation to the characteristic phase profile of M82X-2.

“…The proposed theory explores a spontaneous breaking of gravitation gauge symmetry ( [18,9,10] and earlier references cited therein, which thoroughly discussed in [11,12]).

Rotating Black Holes in Microscopic Theory: the Implications for Periodic Source M82X-2

In previous paper [1], we employ the microscopic theory of black hole to study the observed unusual high luminosity of NuSTAR X-ray pulsations from M82X-2 without the need for significant breaking of Eddington limit. Exploring a spontaneous breaking of gravitation gauge symmetry at huge energies, this theory has smeared out a central singularity of black hole replacing it by the equilibrium, so-called, superdense proto-matter core (SPC), subject to certain rules. In this framework, we think of a M82X-2 as being a spinning intermediate mass black hole. However, for rigorous theoretical solutions, in present report we analytically treat the microscopic model of stationary and axisymmetric rotating black hole. A ring singularity of the Kerr black hole cannot occur, which is now replaced by equilibrium SPC. We calculate the corrections to previous model, introduced by the rotation, of the characteristic phase profile of M82X-2.

To reconcile the observed unusual high luminosity of NuSTAR X-ray pulsations from M82X-2 with the most extreme violation of the Eddington limit, and in view that the persistent X-ray radiation from M82X-2 almost precludes the possibility of common pulsars, we tackle the problem by the implications of microscopic theory of black hole (MTBH). The preceding developments of MTBH are proved to be quite fruitful for the physics of ultra-high energy (UHE) cosmic-rays. Namely, replacing a central singularity by the infrastructures inside event horizon, subject to certain rules, MTBH explains the origin of ZeV-neutrinos which are of vital interest for the source of UHE-particles. The M82X-2 is assumed to be a spinning intermediate mass black hole resided in final stage of growth. Then, the thermal blackbody X-ray emission, arisen due to the rotational kinetic energy of black hole, escapes from event horizon through the vista to outside world, which is detected as ultraluminous X-ray pulsations. The M82X-2 indeed releases ∼ 99.6 % of its pulsed radiative energy predominantly in the X-ray bandpass 0.3-30 keV. We derive a pulse profile and give a quantitative account of energetics and orbital parameters of the semi-detached X-ray binary containing a primary accretor M82X-2 of inferred mass M 138.5-226 M and secondary massive, M 2 > 48.3-64.9 M , O/B-type donor star with radius of R > 22.1-25.7 R , respectively. We compute the torque added to M82X-2 per unit mass of accreted matter which yields the measured spin-up rate.
