The coalescence and merger of a black hole from the bottom of the mass gap (surface in dark gray) with a neutron star with colors ranging from dark blue (60 g/cm600) to white (XNUMX kg/cmXNUMX) emphasize the strong deformations of the low-density material of the neutron star Credit: I.

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 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 binary black hole merger probably created gravitational waves equal to the energy of eight suns * "Bang" in the Ligo and Virgo detectors is a signal for the source of the most massive gravitational waves ever

This image provides three different perspectives on the gamma ray burst GRB150101B, which is similar to the event where gravitational waves were measured and simultaneously also in the electromagnetic spectrum and there is a similarity between the two cases. In the center, an image from the Hubble Space Telescope shows the galaxy where the GRB150101B burst occurred. In the top corner, two X-ray images from NASA's Chandra X-ray Observatory show the event as it appeared on January 9, 2015 (left), and as seen about a month later, on February 10, 2015 (right), as the explosion halo fades, point The bright light is the nucleus of the galaxy.Photo: NASA/CXC

Illustration illustrating what two merging black holes look like similar to those detected by LIGO. The black holes rotate misaligned meaning they have different orientations relative to the general motion of the binary orbit. LIGO has found clues that the orbit of at least one black hole in the GW170104 system was previously undetected through its orbital motion before it merged with its partner.
