Backward Shockwaves From Deep Space Are Puzzling Scientists

By Caroline Delbert

Scientists from the University of Western Australia and Italy’s Università di Bologna have been studying an extremely faraway galaxy cluster, Abell 3266, where they’ve identified three phenomena that are unheard of elsewhere—at least so far. And all three emit radio waves that have allowed us to observe them across a distance so far it almost defies units of measure altogether.

While observing the cluster with the Australian Square Kilometre Array Pathfinder and Australia Telescope Compact Array radio telescopes, the researchers observed three different unusual phenomena: radio relics, radio haloes, and fossil radio sources.

All three of these phenomena are created by energy slamming into abundant plasma. With radio relics, this reaction sends out shockwaves like the sonic booms we experience on Earth. They themselves aren’t unusual in galaxy clusters, but the one these researchers found is backward. The brightness in this area of the cluster suggests that a shockwave should travel from north to south, but instead it goes from south to north. The researchers dubbed this a “wrong-way” radio relic.

The researchers say other scientists have begun to observe other backward radio relics in similar work, showing that this is an uncommon, but not nonexistent, phenomenon. And they theorize that the wrong-way radio relics result from not just energy striking plasma, but multiple subclusters striking each other simultaneously. Think about biting down on a crunchy potato chip versus biting down on a crunchy potato chip that was folded over during manufacturing.

In their new paper, researchers Tessa Vernstrom of The University of Western Australia and Christopher Reisely from Italy's Università di Bologna describe how their discovery of a series of large, low frequency radio wave-emitting objects in a galaxy cluster about 800 million light-years away appear to defy the laws of physics.

"Our best physical models simply can’t fit the data," the researchers wrote in The Conversation. ... snip ...

"Maybe there's some kind of new physics going on there that we haven't fully understood," Vernstrom concluded, "when our models can't match the observations."

Maybe they should consider the possibility that the interaction of current carrying plasma, which emits radio waves, is doing this?

There are none so blind as those who won’t open their eyes (and that applies to lots of things).
