Dark Matter ‘Asteroids’ Revealed in Collisions with Stars
The detection of dark matter has proven more difficult than expected, but astroparticle physicists still rely on natural giant detectors, the stars, to compensate for the weakness of terrestrial detectors.…
Dark matter around the Milky Way betrayed by star currents
The stellar currents that surround the Milky Way reveal a story in which it literally devoured a few of its fellow travelers. But they also deliver precious clues about the…
Webb Space Telescope May Discover First Stars Formed Around Primal Black Holes
Black holes of various masses may have formed during the first second of the Big Bang and ultimately ended up being the source of dark matter. In a new scenario,…
Supermassive black hole is believed to be hiding in dwarf galaxy near Milky Way
This is unheard of and questions the growth models of galaxies and supermassive black holes. The dwarf galaxy Leo I orbiting the Milky Way would contain at its center a…
High-luminosity LHC: what is it?
Engineers and physicists of CERN (European Council for Nuclear Research) are committed to design of a high-luminosity LHC (HL-LHC) making it possible to go from around one billion proton-proton collisions…
There would be a supermassive black hole in a dwarf satellite galaxy of the Milky Way
This is unheard of and questions the growth models of galaxies and supermassive black holes. The dwarf galaxy Leo I orbiting the Milky Way would contain at its center a…
Dwarf galaxies around the Milky Way shine a light on its complex past
On the sidelines of the Gaia mission, American researchers found, by studying the dwarf galaxies orbiting the Milky Way, that the majority of these galaxies had only recently arrived in…
