International research team including scientists from the Australian National Science Agency
The research team usedASKAP radio telescope for a new method of searching for pulsars. They used a kind of "sunglasses" to capture polarized light and found a pulsar that is 10 times brighter than similar objects previously found outside our galaxy.
Observation without sunglasses
“We expect that this technique canwill find even more pulsars. For the first time, we conducted a systematic and regular search for such objects in comfortable conditions. Due to its unusual properties, this pulsar was missed by previous researchers, although it is very bright, ”the scientists noted.
A pulsar is a rapidly rotating neutrona star with a magnetic field that emits two beams of polarized radio emission. As the rays streak through space, they create unique impulses that come to Earth.
Observation with "sunglasses"
The traditional methods of searching for pulsars are the search forscintillations in the telescope data. But this way you can miss too fast or too slow pulsars. If instead scientists look for polarized light, they might find pulsars outside the standard time range.
Moreover, scientists have already found signs of this pulsar, but the bright spot in the radio data was mistaken for a distant galaxy.
