Pune: For the previous 4 years, Giant Metrewave Radio Telescope (GMRT), close to Pune, and Ooty Radio Telescope have been engaging in experiments in pulsar timing and retaining a database of the same.
With the 10th annual meeting of International Pulsar Timing Array Collaboration being hosted in Pune from June 17 to 21, India is hoping to quickly become a permanent member of International Pulsar Timing Array Collaboration.
Pulsar is a highly magnetized rotating celestial object of very top mass that emits a beam of electromagnetic radiation. “The radiation can be seen when it issues in opposition to the earth as pulses of emission, which seem with clockwork precision. Hence, they are the best celestial clocks,” stated Gopakumar, senior scientist, Tata Institute of Fundamental Research (TIFR), Mumbai
“Now, if there is a gravitational wave passing previous the pulsar, there might be a blip or difference in the in a different way disciplined pulses. By learning this alteration over a time frame, we will determine a trend in it. This trend will tell us concerning the gravitational waves. Now gravitational waves are like waves with a ripple impact just like the ripple impact we see when a pebble is dropped in a nonetheless pond. Instead of the up and down motion, the G waves are like sound waves; they increase and compress,” stated Mavia McLaughlin, professor of physics and astronomy, West Virginia University, america.
The Indian team has been accumulating knowledge on the arrival time of pulsars. “More the information on arrival time of pulsars, extra we will understand if there is a trend of exchange in them and the cause. So knowledge assortment and research of pulsars are being finished by way of the Indian team,” stated Andrea Lommen, professor of astronomy and physics, Haverford College, america.
IPTA is a collaboration of radio astronomers from a dozen countries world wide which makes use of 12 radio telescopes with an aim to detect ultra-low frequency gravitational waves (nano-hertz gravitational waves). The first gravitation waves detected by way of LIGO used to be a top frequency wave, while what IPTA is trying to detect has a frequency of a few billionth of a 2nd.
