Some of the most extreme explosions in the universe are Type I superluminous supernovae. “They are one of the brightest ...

An international team from China and Italy has reported a possible cosmic encore to the landmark 2017 multi-messenger ...

Astronomers have discovered a strange new signal coming from an exploding star — a “chirp” that speeds up over time, similar to the signals seen when black holes collide. The unusual pattern appeared ...

The findings confirm a theory first proposed 16 years ago by University of California, Berkeley theoretical astrophysicist ...

Over time, the disk gradually falls inward toward the magnetar. Closer to the star, the frame-dragging effect becomes stronger, and the disk wobbles faster. This is why the bumps in brightness occur ...

Researchers report superluminous supernova SN 2024afav whose erratic behavior supports a long-standing theory of stellar ...

Pushed down to a certain scale, the laws of physics seem to fall apart. Astrid Eichhorn, a leader in an area of study called asymptotic safety, thinks we just need to push a little further.

For decades, astronomers have used distant supernovae as cosmic lighthouses to test fundamental physics and to measure the ...

The catalog of gravitational waves "heard" by LIGO, KAGRA and Virgo has doubled with detections of spacetime ripples.

Scientists propose a gravitational-wave method called the stochastic standard siren to measure the Hubble constant, offering an independent way to examine the universe’s expansion and the Hubble ...
