The discovery of unusually fast-moving stars in the Milky Way globular cluster ω Centauri provides evidence for the potential presence of an intermediate-mass black hole at its center.
บทคัดย่อ
The article discusses the ongoing search for intermediate-mass black holes, which are believed to be essential building blocks for the supermassive black holes found at the centers of galaxies. While a few candidates have been identified, a significant gap remains in this mass range.
The key highlights from the article are:
- Intermediate-mass black holes, with masses between 100 and 100,000 times the mass of the Sun, are one of the most elusive members of the astrophysical object class.
- Evidence is mounting that the mergers of pairs of black holes, such as those detected through gravitational waves, could produce intermediate-mass black holes, particularly in dense stellar environments.
- Häberle et al. report the discovery of unusually fast-moving stars in the Milky Way globular cluster ω Centauri, which offers evidence that an intermediate-mass black hole might be present at the center of this cluster.
- The discovery of these fast-moving stars provides a potential new avenue for identifying intermediate-mass black holes, which have been difficult to detect using other methods.

Intermediate-mass black holes have masses between 100 and 100,000 times the mass of the Sun.
The Milky Way globular cluster ω Centauri is the focus of the study.

"Intermediate-mass black holes remain one of the most elusive members of an already exotic class of astrophysical objects."
"Evidence is also mounting that the mergers of pairs of black holes, such as those detected through gravitational waves, could produce intermediate-mass black holes, particularly in dense stellar environments."
