On Feb 11, 2016, he was invited to the synchronised announcement of the first discovery of gravitational waves at IUCAA. The first picture shows a visibly emotional Vishu reacting to observational revelation of quasi-normal modes (now more popularly dubbed the “ring down” signal) of black holes predicted by him long back as a graduate student in 1972.
At this event, he also witnessed the growing community of LIGOIndia and was thrilled to see the energy and enthusiasm among the young researchers. In the second picture, he is shown pictured with a large part of the rapidly growing group of Indian researchers of the gravitational wave.
Besides his larger that life stature as an excellent academic, he endeared himself to the entire science world with his witty comments, humorous after-dinner speeches and amazing science cartoons.
