New Delhi: The inaugural data release of the Indian Pulsar Timing Array partnership included a team from the Indian Institute of Technology Roorkee (IIT-R). With the help of the International Pulsar Timing Array (IPTA), the Indo-Japanese partnership aims to discover low-frequency gravitational waves.
The InPTA data for this year was collected over a period of three and a half years utilising the upgraded Giant Metrewave Radio Telescope (uGMRT), which is run by NCRA-TIFR close to Pune. The partnership has been actively pursued by P Arumugam of the physics department of IIT Roorkee and his team, which also includes PhD candidate Jaikhomba Singha and IITR alumni Piyush Marmat. The study was recently published in the Publications of the Australian Astronomical Society.
Researchers have been listening in on gravitational waves, which are produced when supermassive black hole binary pairs collide after millions of years of orbiting one another. The immense ocean of interstellar media between them is the main obstacle to their detection. For mapping this intergalactic "weather" and opening the door to the discovery in the near future, the InPTA data is essential.
P Arumugam, emphasising the significance of this work, said: "This is an important release of our collaboration and will eventually help detect gravity waves in a new window."
On November 25, 2022, the institute recently celebrated its 175th anniversary of founding. The gathering included faculty, employees, alumni, and students. Events included the Kavi Sammelan, Startup Expo, and Drone Show, among others. The celebration was attended by a number of luminaries.
