The analysis of the signal GW230529 picked up by LIGO shows that it originated from the merger of two compact objects, one with a mass between 1.2 and 2.0 times that of the Sun and the other with a mass slightly more than twice the first

The CSOs emit jets for 5,000 years or less and then die out. "The CSO jets are very energetic jets but they seem to end, the jets stop flowing from the source

A new theoretical analysis puts the probability that massive neutron stars harbor non-configurational quark nuclei between 80 and 90 percent. The result was achieved through massive computer runs using Bayesian statistical inference.

"The effect of gravitational waves on pulsars is very weak and difficult to detect, but we built the credibility of the findings over time as we collected more data," said Caterina Cazziano, NANOGrav team member and senior lecturer at Caltech.

A team of researchers from Australia recently made a new prediction about the strength of this gravitational wave signal. The new estimate is based on data from the MassiveBlack-II imager, which simulates a massive region of space that resembles a slice of our universe

The Hubble Space Telescope photographed a bright knot of gas hit by an invisible jet from the black hole, which is only 15 light years away. The black hole must have looked bright billions of years ago as a quasar, when our young galaxy was fed by lots of infalling gas. But after all this time the black hole is acting sporadically, unwilling to take a nap

The Laser Interferometer Gravitational Wave Observatory (LIGO) in the US and the Virago Gravitational Wave Observatory in Italy captured the gravitational waves from the death spiral and merger of a neutron star with a black hole, not once but twice. The findings were recently published in The Astrophysical Journal Letters

Researchers from Prague published in the prestigious journal Physical Review Letters an alternative model for dark matter based on MOND that succeeds in predicting the existence of the cosmic background radiation. This is a significant achievement that the MOND model has so far failed to explain, and for this it has received most of the criticism against it. the price? Two new fields in Teva. The authors of the article hope in the future to prove its existence with the help of the model's unique fingerprints on the gravitational waves.
