Direct collapse black hole candidates from decaying dark matter: https://iopscience.iop.org/article/10.1088/1475-7516/2026/04/034 -> Dark matter could explain earliest #SupermassiveBlackHoles: https://news.ucr.edu/articles/2026/04/15/dark-matter-could-explain-earliest-supermassive-black-holes - dark matter decays could be the missing ingredient explaining how giant black holes formed before the first stars.

This evening I learned the following bizarre things:
0/ Colliding massive objects create gravity waves (this I already knew).
1/ When spinning black holes collide, they experience an acceleration at right angles to the sum of the spins.
2/ The bigger the black holes, the greater the acceleration and resulting speed.
3/ When this happens with galactic core supermassive black holes, this can exceed the escape velocity of the galaxies.
4/ When one of these high-speed supermassive black holes encounters a dust or gas cloud, it creates a contrail of stars! And we can see these star-contrails - straight lines of stars, scattered across the cosmos!Thank-you Professor David Blair!

It looks like the end of a mosquito's proboscis has run amok.

While we're on the subject of the horrifying scale of the Universe, I cannot get over what big fat bastard the SMBH at the centre of M87 is when compared to ours!

Was reading some online slides and came across this excellent #RadioAstronomy image from the NRAO/AUI/NSF.
The terrestrial portion is optical wavelengths. Above this is radio wavelengths.
Those are not stars. They are radio sources.
They're supermassive black holes in the centres of galaxies.
The sky portion of this image was taken by the now fallen 300-ft radio telescope, pictured here as the largest dish between the smaller dishes.
If you had a radio wavelength-detecting eye that was 300 feet in diameter, this is how the sky would look to you.
A sea sprinkled with ancient light.
You can download this image, and use it from this link from the NRAO site here: https://www.nrao.edu/archives/items/show/33605

In Jan, #astronomers announced that the #JamesWebbSpaceTelescope had observed the oldest black hole yet—one present when the universe was a mere 400M yrs old.…Recently, 2 #SupermassiveBlackHoles, w/a combined mass of 28B suns, were measured & shown to have been rotating tightly around each other, but not colliding, for the past 3B years. And those are just the examples that are easiest for the public to make some sense of.

Supermassive black hole binary pair, which have been resolved (!) and are separated by a mere 24 light-years (P_b = ~30,000 yrs) whilst suffering from the Final Parsec problem have had a new mass reported in this paper ... and the combined mass comes in at a whopping 28 billion Suns!
