ICWA Ep-01: A Decade After GW150914: K G Arun on LIGO-India and What Comes Next

In this first episode of In Conversation with AnandO, I sit down with Prof K G Arun (Chennai Mathematical Institute), one of the leading figures in gravitational-wave physics and an important voice in India’s growing role in the field. We begin with a vivid moment from 2015, when the collaboration realized GW150914 was not a blind injection and the discovery became real. Arun then traces his path from early post-Newtonian waveform work during his PhD with Prof Bala Iyer, to his broader exposure through Virgo, and finally to helping shape India’s gravitational-wave community. We talk about why waveform accuracy sits at the heart of the enterprise, from precision parameter estimation to increasingly stringent tests of General Relativity. Arun also reflects on how GR tests have matured across the catalogs since GW150914, and what new detectors will demand from waveform modeling in the years ahead. The second half of our conversation turns to LIGO-India. Arun shares how he thinks about building a strong national research ecosystem, how Indian scientists are integrating into the broader LVK community, and what it takes to mentor and retain the next generation as the long commissioning road begins. We close by looking forward to the next decade, including sources Arun is especially excited about, such as neutron star–black hole mergers and the possibility of multi-messenger discoveries once LIGO-India joins the global network. I’d love to hear your thoughts and suggestions in the comments, and who you’d like to see in future episodes.
