Monitored in the radio since its discovery and more recently in the infrared and the X-ray, Sgr A* appears to be accreting material at a very low rate, only a few hundredths of an Earth-mass per year.  This is where the concept of X-ray communications (XCOM) come into play, which offer even more in the way of advantages than lasers. For one, X-rays have much shorter wavelengths than both radio waves and lasers and can broadcast in tighter beams.  In a new study published Aug. 17 in Nature Communications, Nemsak, Fadley, Schneider and colleagues demonstrate the use of new techniques in X-ray spectroscopy to illuminate the internal structure of manganese-doped gallium arsenide.
