Black Hole as a Consideration in Explanation for the Recently Detected Unusual Fast Radio Burst (FRB) Heartbeat Pulse from Outer Space

Black Hole as a Consideration in Explanation for a Recently Detected Unusual FRB Pulse from Outer Space, In Regard to a Recent Science-Related News Articles on a Mysterious .20-Second FRB Pulse Recurring for the Unprecedented Total Duration of 3 Seconds and of the Source Energy Output of Hundreds of Millions of Suns

 

On 07-19-2022 I read a science news article on the mysterious .20-decimal second, recurrent FRB resembling a heartbeat pattern and lasting for a record total duration for an FRB of 3 seconds.  The article reported that the energy source of that FRB would have to have been that of hundreds of millions of solar masses, and that pulsar or magnetar neutron stars that otherwise could explain the source of past FRBs did not fit as sources because of their single digit masses, equated with energy magnitude, recurrent heartbeat pattern and comparative, to past FRBs, extreme duration.  I attempted to save the article, to which I posted the following comment; however, the article did not save.  So I tried to research it online but could not find an article mentioning the reference to the hundreds of millions of solar masses but I did find a reputable science article on the same FRB without reference to the said solar-mass energy, whose click-on hyperlink is posted at the conclusion of this herein Twitter post of mine.  The comment I posted was:  “Celestial FRBs (fast radio-wavelength bursts) associated with the energy output of hundreds of millions of times of the energy magnitude of or output produced by our sun, our solar-planetary system's star, within a decimal second or three seconds could only be produced by a supermassive black hole, of equivalence or greater in mass, of some kind and in some way, and nothing else.” (I actually used the term milliseconds, which I saw in the numerous news stories I read on this particular FRB but which I knew was the incorrect term, instead of the term decimal seconds, an imperfect term but the best fit, in my aforementioned quoted comment.)  Supermassive black holes with such magnitudes of solar masses are well known to astronomers and human astronomy to exist.

 

In afterthought, I add the caveat that there is a weak outside chance that a small galaxy or large star cluster (a globular star cluster) with hundreds of millions of solar masses, rotating globularly as a unit, at the extreme speed of a pulsar or magnetar neutron star, or a black hole, that could be the energy source and cause of this particular heartbeat repeating FRB, a weak chance because neither a small galaxy nor globular cluster of stars has ever shown anything close to the observed necessary extreme spin velocity to generate the decimal-second time of any FRB, including the concerned FRB, whereas pulsar and magnetar neutron stars commonly have and so have black holes, some black holes of which have been radio-telescopically clocked to spin at half the speed of light, circa 335,000,000 miles per hour.  Nor has any galaxy, small or large, nor globular star cluster made of up of only or primarily either or a mix  of pulsar and/or magnetar neutron stars, or all variety of neutron stars, ever been reported to have been observed in the astronomical observations of astronomy.  Among other explanations as to how a black hole or black holes could produce this and some of the other FRBs, is the one that when two or more black holes merge, they probably generate more than outwardly going gravitational shock waves, insofar as their individually orbiting huge and powerful accretion disks of volatile chemical gas and particulate matter, and photospheres, most probably collide during their merger and ignite or trigger a chaos of astronomically large and powerful explosions of all possible kinds, possibly including nuclear explosions, that as a result radiate their own concomitant, with gravitational waves, radio frequency or wavelength blasts, and/or nuclear explosion-related EMP (electromagnetic-pulse) blast/s, into and through the surrounding outer space of the universe.  Supermassive black holes, of hundreds of millions to billions of solar masses in magnitude, might have gravitationally entrained orbiting satellites, beyond their accretion disks and toruses, of stars, with or without celestial-body solar systems, whose stars might include neutron stars, maybe pulsars and/or magnetars, and binary, or multisystem, stars, that are absorbed in, and smash up during, the black hole mergers and in some situations are cause for or contributors of cause for the concerned FRBs.
