Monster structure discovered that could contain 30 Milky Ways

According to Science Alert, Inkathazo is a giant radio galaxy, a group of monster structures in the universe, with many unusual characteristics and difficult to detect.

According to astrophysicist Kathleen Charlton (University of Cape Town - South Africa), co-author of the study on Inkathazo, the name of this giant galaxy means "trouble" in isiZulu and isiXhosa, the indigenous languages ​​of South Africa.

That's because understanding the physics behind what's going on with these types of hyper-objects is incredibly difficult.

Radio galaxies have had physical properties that have puzzled scientists, with supermassive black holes accreting matter at the galactic core and emitting giant jets of plasma that glow at radio frequencies.

Galaxies larger than about 2 million light-years across can be classified as giant radio galaxies, or GRGs.

 

According to the research team, the "monster" Inkathazo has a diameter of up to 3 million light years, enough to trap 30 of our Milky Way galaxies.

In addition, it also reveals some unusual features compared to other giant radio galaxies.

For example, the plasma jets have an unusual shape: Instead of extending straight from one end to the other, one of the jets is curved.

Additionally, Inkathazo lies in the middle of another galaxy cluster, where conditions would prevent the development of such giant jets.

In hopes of unraveling the mysteries of Inkathazo, the researchers used MeerKAT to create high-resolution spectral age maps of the galaxy, which could reveal the age of the plasma in different regions inside the monster.

This map shows anomalies in Inkathazo's jets, where something mysteriously powers some of the electrons.

This may reflect the impact of the wider cosmic neighborhood, the authors say.

Instead of shooting its plasma into relatively empty space, Inkathazo's jets erupt into the intergalactic voids in its galaxy cluster, where their interactions with hot gases could explain the strange energy surge.

'These findings challenge existing models and show that we still have much to learn about the complex plasma physics at play in these extreme galaxies,' the authors write in Monthly Notices of the Royal Astronomical Society.
