An international team of astronomers has employed the MeerKAT radio telescope to investigate giant radio galaxies in the field of the Cosmological Evolution Survey (COSMOS).
- They found a new giant radio galaxy that had not been reported before.
- The giant radio galaxies (GRGs) are radio galaxies with an overall projected linear length exceeding at least 2.3 million light years.
- They are rare objects grown usually in low-density environments and are observed to display jets and lobes of synchrotron-emitting plasma.
- GRGs are important for astronomers to study the formation and the evolution of radio sources.
- The MeerKAT radio interferometer located in South Africa is an excellent instrument to study GRGs at high frequencies (about 1.0 GHz).
