The first pulsar was observed in 1967 near Cambridge (UK). Since then, more than 3,000 other pulsars have been discovered. The most in our area Ciro just made an amazing discovery there. This bright spot that researchers have taken until then for a distant galaxy would in fact be just another pulsar in the heart of the Large Magellanic Cloud. And not just any pulsar. The one they named PSR J0523-7125 would be the brightest pulsar ever observed outside the world . Perhaps even the brightest pulsar ever!. But about thirty isomorphs, in our nearest neighbour, the . And today, thanks to a new technology
To understand how such an object could go under the radar so far, it is necessary to know that classically, to find pulsars, astronomers look for the characteristic recurring signals that such amazing objects leave in the data of. The method is effective. Most of the time. Because it tends to fail to detect pulsars that are out of the ordinary. Pulsars are too fast or too slow. but also those who ” » dispersed.
There are still plenty of pulsars to discover
To discover this type of pulsar, the researchers imagined they could rely on another property of pulsars. In fact, its rays can be very circularly polarized. Understand that the electric field of their light waves takes a circular motion as the waves travel through space. These signs are rare.
But specifically, theAustralian Square Kilometer Pathfinder Arraythe Australian Square Kilometer Radio Telescope Array (Askap), has types of “» Let him pick this up polarized. And it was the student who finally discovered, in the data from the machine, a circularly polarized object, in a place where there is no known pulsar.
Thanks to this new technology, astronomers now hope to discover other pulsars outside the galaxy. And why not, pulsars lie behind the Large Magellanic Cloud. Observations that will help them better understand the processes still hidden behind these extremes.
