In search of gravitational waves, astronomers listen for the music of black holes

In order to listen to the “symphony of black holes in the universe,” an international team will need to share the first set of data that Indian scientists have collected.

When they are discovered, these low-frequency gravitational waves will give researchers a fresh perspective on the universe via a window that was initially opened in 2015 with the discovery of the first gravitational wave.

Gravitational waves are incredibly tiny ripples in spacetime that are produced by extremely heavy objects, such as black holes. But since they are so elusive, it took scientists decades and a roughly $1 billion equipment to finally catch them. Some …

However, that only told half of the story. Since it is more difficult to identify low-frequency waves, all gravitational wave fingerprints discovered so far are high-frequency waves. This is what a global partnership spanning four continents looks like.

It is comparable to viewing a star in the X-ray spectrum rather than the visible spectrum. The star must be seen from both sides of the electromagnetic spectrum to provide a complete picture, according to main Indian researcher Bhal Chandra Joshi from the National Center of…
