Quest for source of black hole dark matter

Aug. 13, 2018 -  
Like a game of “hide and seek,” Lawrence Livermore astrophysicists know that there are black holes hiding in the Milky Way, just not where. If they find them toward the galactic bulge (a tightly packed group of stars) and the Magellanic Clouds, then black holes as massive as 10,000 times the mass...

Lab researchers find magnetic fields impact atmospheric circulation of gas giant planets

Aug. 9, 2018 -  
Magnetic fields around a planet or a star can overpower the zonal jets that affect atmospheric circulation. New research by a Lawrence Livermore National Laboratory ( LLNL ) scientist and a collaborator from the Australian National University (ANU) provides a theoretical explanation for why self-...
