Energetic radiation pulsing from the belly of the Milky Way is the clearest signal yet of dark matter. That is according to a pair of astrophysicists in the US who reach this conclusion after scrutini...
Stellar models of massive single stars are still plagued by major uncertainties. Testing and calibrating against observations is essential for their reliability.
