Rare Distant Radio Galaxy Spotted

Astronomers have recently used an Indian telescope to discover the rare distant radio galaxy. It is located at a distance of 12 billion light-years meaning it is from a time when the universe was only seven percent of its current age. Giant Meter-Wave Radio Telescope (GMRT) in Pune found this rare distant radio galaxy.

GMRT is a collection of thirty steerable parabolic radio telescopes of a 45-meter diameter which is operated by the National Center for Radio Astrophysics.

The distance of this galaxy was calculated by using the Gemini North telescope in Hawaii and the Large Binocular Telescope in Arizona.

According to the study in the journal Monthly Notices of the Royal Astronomical Society, the galaxy was only a billion years old. It also stated that the light coming from this galaxy is almost 12 billion years old. The most astounding fact here is how these galaxies are built in such a short span of time which will port into supermassive black holes later.

Radio galaxies are very rare objects in the universe as they are enormous galaxies with a supermassive black hole in their center. These supermassive black holes accrete gas and dust from its surroundings which initiate the coming up of high-energy jet streams. This will accelerate the pace of charging particles to the speed of light.

These jets can be easily seen at radio wavelengths. To the astronomers’ eyes, the fact of having such galaxies in the distant universe is stupefying.

Having known about such discoveries and elements is extremely important for the formation and evolution of galaxies and about black holes too as this surely has the potential to understand the universal mechanism.

Let’s now wait for some more new updates about this study with upgraded Giant Meter-Wave Radio Telescope (GMRT).
