Scientists discovered a completely new class of radio-emitting object in the Galaxy


Radio signals from cosmos were all the time an interesting subject. An international team of scientists led by members of the ERC-funded MeerTRAP (More Transients and Pulsars) group at The University of Manchester, using the MeerKAT radio telescope in South Africa, has discovered a strange radio-emitting neutron star, which rotates extremely slowly, completing one rotation every 76 seconds. They named the neutron . Most pulsars spin extremely quickly, on the scale of milliseconds to a few seconds, but this is very different. Theoretically, isn’t just a curiosity , it should be an impossibility. It seems to have at least seven different pulse types, some of which are strongly periodic. The team aren’t sure how its emissions are generated. The object has an odd mix of characteristics from pulsars, ultra-long period magnetars and fast radio bursts. Dr. Manisha Caleb, formerly from The University of Manchester and now at the University of Sydney, who led the research, said: “Amazingly, we only detect radio emission from this source for 0.5% of its rotation period. This means that it is very fortuitous that the radio beam intersects with the Earth. Therefore, it is likely that there are many more of these very slowly spinning sources in the Galaxy, which has important implications for how neutron stars are born and age.” This was discovered in a well-studied part of the Galaxy.


This new finding strengthens the case for a new type of radio transients known as ultra-long period neutron stars.In fact, the researchers have found a completely new class of radio-emitting object, in a region where scientists don’t expect to detect any radio emissions at all. It’s not known how many of these sources might exist in the galaxy. Future searches for similar objects are needed.
