Signs that black holes swarm at galaxy centre
A swarm of 10,000 black holes may be orbiting the Milky Way’s supermassive black hole. This estimate is based on theoretical expectations of the migration of black holes in our galaxy and the ob...

New measurements of unstable nuclei caught in the act of decay have gone a long way towards resolving long-standing questions about the triple-alpha process that creates carbon nuclei.
A team from Case Western Reserve University in Cleveland, Ohio, and CERN has discovered surprising evidence that the largest-scale features of the microwave sky seem to be correlated with both the mot...
The general relativistic prediction of the Lense-Thirring effect has been confirmed to a precision of less than 10%. The result was obtained by measurements of the position of two satellites over a pe...
Is the recent detection of very-high-energy gamma rays from the galactic centre revealing the presence of dark matter? Or, is dark matter at the origin of the electron-positron annihilation in our gal...
Tiny black holes could offer a richer view of physics than their better known, moremassive relations, as Aurélien Barrau and Julien Grain explain.
ICHEP'04, the 32nd International Conference on High Energy Physics, was successfully held in Beijing from 16-22 August, hosted by the Institute of High Energy Physics (IHEP) and the Chinese Academy of...
The discoveries of three new extrasolar planets were recently announced within the space of a week. With masses around or less than 20 times that of the Earth, these new exoplanets are the lightest kn...
Observing what goes on in the heart of stars from deep below ground is an effective tool for understanding stellar interiors and the primordial universe, as Gianni Fiorentini and Alessandro Pascolini ...
A peculiar gamma-ray burst has been detected by ESA’s INTEGRAL gamma-ray mission. This sub-energetic burst makes the link between an earlier anomalous event and all other bursts detected so far....
