Pune: Fergusson College lecture delves into ‘mysterious orgin’ of gold

On August 17, 2017, for the first time in human history, Gravitational Waves from the merger of neutron stars were detected. This gravitational wave was named GW170817 and the evidence of r-process nucleosynthesis was also obtained. However, the birthplace of gold remains unclear, Yoshida added.

The upcoming Laser Interferometer Gravitational-Wave Observatory (LIGO) India project would be crucial for improved accuracy for astronomical measurements, said Yoshida. Speaking to The Indian Express, he said, “With LIGO India, the localisation of the gravitational waves will improve so much. We need as many of these detectors as possible. They can identify a more accurate location of the gravitational wave.”

IUCAA hosted a senior level Japanese delegation from the National Astronomical Observatory of Japan (NAOJ) on Monday. The delegation discussed possibilities of future collaboration with Indian Astronomers.
