Dieter Lüst and co-authors argue KM3NeT's record neutrino, about 35 times more energetic than any before, came from a black hole exploding in a fifth dimension. The idea explains the missing photons but rests on one detection and an unproven extra dimension.

Khalifa University mathematicians proved that two very different waves ring at identical frequencies around black holes of five or more dimensions. Adding a string-inspired correction pulls the tones apart, but only in black holes smaller than any extra dimension and beyond the direct reach of detectors.

Niels Bohr Institute astrophysicists ran 195 collapsing-star models and found neutrino flavor conversion flips the outcome for stars of 16 to 30 solar masses. The density at which conversion begins is still an input, so the effect on supernova counts is unmeasured.

Stefano Profumo ran twelve dark matter scenarios through the Barbieri-Giudice sensitivity test in Physical Review D. A popular particle model tied to a Higgs resonance came out among the most fine-tuned of the set.

The Kyoto-led model says an axion signal should peak in Southeast Asia, but the decade of records came from Britain, and the several unexplained dark photon candidates it also turned up cannot be checked from one station.

A calculation of the race between accretion and Hawking radiation puts the smallest black hole that can grow inside a Galactic bulge white dwarf at about 40 metric tons, roughly 250,000 times below the no-feeding threshold.

If the Universe's first supermassive black holes grew out of stars heated by WIMP dark matter, that history would still sit in a background measured billions of years later. A two-author Letter says the share could be dominant.

A Physical Review D paper argues cosmic acceleration is a residue of quantum uncertainty acting on geometry, which would turn two unsolved problems into one. Upcoming surveys are the test.

A Colgate University pair argue the nanohertz gravitational-wave background may be dominated by descendants of dark-matter-powered stars, which makes the signal an abundance limit on early seeds.
