The challenges of satellite communications on the move
... power levels to supply the many active elements needed to produce the characteristics and orientation of the antenna beam or beams. Such power demands can be difficult for some mobile platforms to supply and regulate, so this needs to be factored...

High-energy theory models questioned as neutron star produces most energetic pulsed emission radiation ever detected
... large absorption in the magnetised atmosphere. Surprisingly, however, the TeV beams arrive at the same time as the radio and X-ray beams. This tight synchronisation of the beams at different energies implies that the bright radiation observed in the...
