Pune’s upgraded Giant Metrewave Radio Telescope (uGMRT) has captured rare radio signals from a supermassive black hole in galaxy J1007+3540, reigniting after 100 million years of silence. The discovery offers unprecedented insights into black hole life cycles, jet activity, and galaxy-cluster interactions, marking a milestone in global astrophysics.

In a breakthrough that places India at the forefront of global astrophysics, scientists using Pune’s upgraded Giant Metrewave Radio Telescope (uGMRT) have detected a supermassive black hole awakening after an extraordinary dormancy of nearly 100 million years. The black hole, located in the giant radio galaxy J1007+3540, revealed powerful radio jets that had long been silent, now reigniting with fresh activity.

This rare observation allows astronomers to study the complete lifecycle of supermassive black holes, from their active phases to dormancy and eventual reactivation. The findings are expected to reshape understanding of how black holes influence galaxy evolution and intergalactic environments.

Key Highlights:

The uGMRT captured low-frequency radio images showing twin jets emerging from the galaxy’s center, with a visible break where the jets collided with surrounding cluster medium.
The black hole’s reactivation after 100 million years provides a unique opportunity to study how such cosmic giants “wake up” and resume energy outflows.
Scientists emphasize that this discovery will help decode the mechanisms behind black hole fueling, jet formation, and their impact on galaxy clusters.
The uGMRT, operated by the National Centre for Radio Astrophysics (NCRA-TIFR), is the world’s most sensitive radio interferometer at low frequencies, with thirty 45-meter antennas spread across 25 km.
Upgrades to the GMRT have tripled its sensitivity, enabling astronomers worldwide to capture faint cosmic signals that were previously undetectable.
The discovery underscores India’s growing role in cutting-edge space science, with uGMRT contributing to international collaborations on black hole physics and radio astronomy.

This milestone not only enhances scientific knowledge but also strengthens India’s position in global astrophysical research, offering a deeper look into the mysterious behavior of black holes and their influence on the universe.
