The team suggests that if there are small mountains on pulsars, China’s FAST (Five- hundred-meter Aperture Spherical ...

Caltech simulations reveal what happens when black holes collide with neutron stars—violent cracking, intense shock waves, ...

After years of there being few alternatives to the Apple-approved LG UltraFine 5K and later the Apple Studio Display in the ...

A hypothetical object, the black hole pulsar, could briefly form during this process. Elias Most describes this phenomenon as a traditional pulsar, but powered by the black hole as it absorbs the ...

A neutron star's final moments may spark violent starquakes, monster shock waves, and even a fleeting, never-before-seen object called a black hole pulsar.

When a black hole and a neutron star finally meet, the result is cosmic carnage—and now, thanks to Caltech’s latest supercomputer simulations, we’re getting a front-row seat to the whole ...

Yoonsoo Kim et al, Black Hole Pulsars and Monster Shocks as Outcomes of Black Hole–Neutron Star Mergers, The Astrophysical Journal Letters (2025). DOI: 10.3847/2041-8213/adbff9 ...

The stars in a binary can vary widely in mass, size, and brightness, and their interactions often shape their evolution in dramatic ways. In some cases, the gravity from one star can drag material ...
