Do the Milky Way's companions spell trouble for dark matter?

(Phys.org) -- Astronomers from the University of Bonn in Germany have discovered a vast structure of satellite galaxies and clusters of stars surrounding our Galaxy, stretching out across a million light years. The work challenges ...

Observations challenge cosmological theories

Recent observations have created a puzzle for astrophysicists: Since the Big Bang, fewer galaxy clusters have formed over time than were actually expected. Physicists from the university of Bonn have now confirmed this phenomenon. ...

Cornell theorists continue the search for supersymmetry

(Phys.org) —It was a breakthrough with profound implications for the world as we know it: the Higgs boson, the elementary particle that gives all other particles their mass, discovered at the Large Hadron Collider in 2012.

Large Hadron Collider smashes another record

The world's biggest particle collider set a new record early Monday, a feat that should accelerate the quest to pinpoint the elusive particle known as the Higgs Boson, a senior physicist said.

BaBar experiment data hint at cracks in the Standard Model

(Phys.org) -- Recently analyzed data from the BaBar experiment may suggest possible flaws in the Standard Model of particle physics, the reigning description of how the universe works on subatomic scales. The data from BaBar, ...
