Scientists know very little about the mysterious force dubbed “Dark Energy” that seems to be quickening the expansion of the universe but, according to LSU Physics and Astronomy Associate Professor ...
RECENT spectral surveys of discrete radio sources have not revealed any significant dependence of spectral index on apparent intensity 1–3. It is therefore of interest to determine the way in which ...
