Supernovas discovered in interstellar space

Recently, astronomers were surprised by the many radiation-emitting “cosmic circles” – they named them strange radio circuitsThey are simply strange radio circuits.

monster It was first discovered using one of the most powerful radio telescopes in the world. Australian Square Kilometer Pathfinder Array (ASKAP) in Australia. These things looked huge with some distinctive features. One of the main features is that At their center is a galaxy.

Scientists believe that ORCs are the result of a complex energy process. However, the exact nature of this process is unknown.

The possibility was associated with the creation of an ORC spherical shock wave Associated with fast radio bursts, gamma ray bursts, or neutron star mergers. However, the “circular features” seen in radio images usually represent spherical objects such as supernova remnants, planetary nebulae, and stellar crust.

ORCs can only be observed in the radio wave spectrumnot visible in the spectrum of visible, infrared, or X-ray waves.

However, there are several key differences between the discovered enigmatic structure and ORC.

In a new facility The galaxy is missing placed in the center of the ball. The index of the radio emission spectrum is flatter than that of the ORC spectral index, and the apparent magnitude of the fuzzy structure is larger than that of the ORC.

Scientists confirm the uniqueness of the discovery and Estimated age of the structure from 2200 to 7100 years.

If the scholars are right, J0624-6948 will be the first intergalactic supernova remnantever identified. The structure is about 155 light-years in diameter, according to the team’s measurements.

The search was published in Monthly Notices of the Royal Astronomical Society.
