Sentences with phrase «lightest black hole binary»

GW170608 is the lightest black hole binary that LIGO and Virgo have observed — and so is one of the first cases where black holes detected through gravitational waves have masses similar to black holes detected indirectly via electromagnetic radiation, such as X-rays.

Not exact matches

However, the team says the nebula's light spectrum is different to that of a black hole jet seen in a binary system called SS 433.

Giant binary stars, for example, typically produce black holes lighter than the ones LIGO sees and too far apart to merge.

The team sifted through data from all the x-ray sources situated within 70 light - years of Sgr A *, searching for those that had characteristics of black holes and neutron stars in binary systems and found four sources within just three light - years of the central black hole.

Such events could include the mergers of lighter binary black holes, of binary neutron stars or of a black hole with a neutron star.

In such a cluster, massive stars would sink towards the centre and, through complex interactions with lighter stars, form binary systems, possibly long after their transformation into black holes.

Findings from this and two previous discoveries of black hole mergers are providing the WSU scientists and colleagues at the Laser Interferometer Gravitational - Wave Observatory (LIGO) an unprecedented glimpse into the early universe and shedding new light on how binary black holes form.

But its announcement was delayed due to the time required to understand two other discoveries: a LIGO - Virgo three - detector observation of gravitational waves from another binary black hole merger on August 14, and the first - ever detection of a binary neutron star merger in light and gravitational waves on August 17.

[Laughter] The binary black hole system we detected was 1.5 billion light years distant.
