Radio Astronomy in the News
The track of an elusive, energetic neutrino points to a distant galaxy as its source and VLA observations suggest high-energy particles may be generated in superfast jets of material near the galaxy’s core.
The sharp radio “vision” of the VLBA gives astronomers a detailed look at a galaxy as it appeared when the Universe was a small fraction of its current age, giving clues about conditions at that early time.
Harnessing the exquisite sensitivity of the GBT, astronomers have given one of Einstein’s predictions on gravity its most stringent test yet. By precisely tracking the meanderings of three stars in a single system – two white dwarf stars and one ultra-dense neutron star – the researchers determined that even the most massive of objects “fall” in the same manner as their less-dense counterparts.
Atacama Large Millimeter/submillimeter Array
The Atacama Large Millimeter/submillimeter Array in the Atacama Desert, Chile, is the most complex observatory ever built.
