Remember this APOD, where Subr worked up his fantasy of an Intermediate Black Hole in the Trapezium?https://apod.nasa.gov/apod/ap170312.html
At 1,500 light years distance, how hard would it be to pinpoint the theorized black hole due to orbital mechanics, seeing as Subr claims a 70% probability it would be a binary?
Stars are seen orbiting the Milky Way's central black hole at a distance of 25,000 - 28,000 light years. He titled his paper, "Catch Me If You Can": as he failed to give an explanation why the black hole's companion would be so dim as to be non-observable, can it not be claimed he has been "caught"
, and enough, by himself
? " .. likely to be a member of a binary system with ≈ 70% probability. In such a case, it could be detected either due to short periods of enhanced accretion of stellar winds from the secondary star during pericentre passages, or through a measurement of the motion of the secondary whose velocity would exceed 10 kms−1 along the whole orbit."https://arxiv.org/pdf/1209.2114.pdf
His "enhanced accretion of stellar winds .. during pericentre passages" would presumably also enter an accretion disk, yet no detection of the hole's disk.
His modeling software predicted 2 signatures as support for its model choice, and neither has been detected.
Such assertions on his part read more as advertisement for modeling software, and his paper's "surviving peer review" was a review of ultimate
Further, the Trapezium is actually a crowded space at 3 million years of age.
" .. Although one solar mass per 10,000 years
may not seem especially quick, it means that even a stellar-mass black hole could grow completely past the intermediate-mass stage after 10 billion years. In comparison, the universe is about 13.8 billion years old.
These findings suggest that the seeds for supermassive black holes "were created quite early on in galaxies, when things were more dense," Bar-Or told Space.com."https://www.space.com/37299-missing-lin ... holes.html
Subr's modeling found the stars' velocities to be anomalous, yet data was lacking for true direction of travel of each .. and this became permitting for theorizing a black hole's presence without qualification of the possibility as "ultimately"
Here we have actual data to support an intermediate black hole's presence. Would these objects be within the hole's accretion disk? Neutron stars as X-ray emitters? The odds of these objects alignment in the disk offering a beam sweep to Earth? They are pulsing, after all.
"The RXTE data revealed a pair of repeating oscillations in M82 X-1's X-ray emissions."https://www.space.com/26857-medium-size ... y-m82.html
" .. two repeating flares of light [X-ray] . The flares showed a rhythmic pattern of light pulses
" .. the magnetic poles on a neutron star are not necessarily aligned with the spin of the star, so you can get narrow beams that sweep as the star spins, just like a lighthouse.
“And if we happen to be in the path of the sweep we see a flash everytime one of these beams go by and the stars from a distance appear to be pulsing .. "https://spaceflightnow.com/2017/06/19/e ... e-station/
