- An Indian radio astronomers-led team announced the discovery of 34 new giant radio sources.
- Many of these GRSs are among the best known, with two of them pushing against the previously accepted theories regarding their environments.
- J0843+0513 and J1138+4540 is challenging the notion that GRSs grow only in low-density environments.
- They used data from TIFR GMRT Sky Survey Alternative Data Release 1 at 150 MHz.
- Giant radio sources are likely to be the largest single structures in the universe, with end-to-end extents of millions of light years.
- They are driven by supermassive black holes with masses ten million to a billion times that of the Sun, residing at the centre of the host galaxy.
