Where’s the Black Hole, Please?

Letter

Part 2 of 2

 

Calculations apart, a second letter here, on a latest observation, should be most conclusive to outlaw the black hole from the cosmic range. Consider first the following.

 

1.      One was able to speculate black holes, and get away with it, simply because they were holed up in massive galactic centers. Being entirely shrouded by the bulge of stars and gas, such a center was impossible for instruments to penetrate to verify directly what really lies at the center. (Note: In the final perspective, the galactic center would be a region of extreme pressure due simply to the backpressure of radiation from its halo and corona.)

 

2.      However, unlike the individual galaxy, the galaxy cluster does not have a central hub of matter (when properly evolved from the quasar by fragmentation). Hence, the center of the galaxy cluster should still be the region of highest pressure in the entire cluster. And that’s exactly what has now been reported, as will transpire next.

 


 

The rich cluster Abell 520 (z = 0.201) exhibits truly extreme and puzzling multi-wavelength characteristics. It may best be described as a “cosmic train wreck.” …However, the most striking feature is a massive dark core (721h70M/L⊙B) in our weak lensing mass reconstruction. The core coincides with the central X-ray emission peak, but is largely devoid of galaxies. …a mass peak without galaxies cannot be easily explained within the current collisionless dark matter paradigm.

Dear Learned Researchers,

A Dark Core in Abell 520

In reference to your above report, due for publication in the Astrophysical Journal, please be good enough to access (1) and (2) for perusal. You may find these to be of fundamental interest and an indispensable backdrop to your continuing research and interpretation of data.

 

Here, briefly, what you observe in Abell 520 is indeed the birth of the galaxy cluster, by quasar fragmentation, and not a "cosmic train wreck." Such scenes should be increasingly seen across the cosmos with the type of instruments with which you are now privileged. Although the cluster is now depleted of any large fragments of the original quasar, the debris at the cluster center will nevertheless be under extreme pressure, that is, under the backpressure from the cluster superwind emanating from its overall halo and corona. This would also resolve your quizzical statements: "However, the most striking feature is a massive dark core…" and "The core coincides with the central X-ray emission peak, but is largely devoid of galaxies." (In individual galaxies, that is, with visible central hubs, we now wrongly attribute such high-energy emissions to the action of – black hole monsters feeding at the centers!)  

 

Further, for the overall and ultimate concept propounded here on the nature of things, you may find the short preprint in (3) to be a worthwhile port of entry. The response from Physics World to this submission has since been negative, leaving the offer therein for its refutation still open! Would your physics department head at Victoria (or at Caltech), kindly consider being the moderator here (holding the cash in hand!)? Moderator's fee, too, will be paid by me in advance. No joke; no scam; just an earnest appeal to resolve this matter for me early with your profound knowledge and expertise. (The money offered is the least I could do in gratitude. It would be worth every penny for me considering the time I would otherwise be wasting in trying to flog a fundamentally flawed worldview.)

Any feedback would be gratefully received.

Thank you and all the very best in your continued quest for answers.

Sincerely,

Eugene Sittampalam
