    Mega Science Project: LIGO-India Part II

    Mega Science Project: LIGO-India Part II

    In part 1 of my conversation with Prof Debarati Chatterjee, we covered her journey to becoming an astrophysicist & working at Inter-University Centre for Astronomy and Astrophysics (IUCAA). Then we talked about key concepts needed to understand Gravitational Waves and modeling pasta-like structures within Neutron Stars.
    In this part we’ll start by covering the basics of Laser Interferometer Gravitational Wave Observatory (LIGO). Then we talk about the challenges of building LIGO-India and its position in the global array of gravitational wave detectors. We’ll close out with the importance of doing this Mega Science project and need for more public outreach.
    I hope you enjoy this one!
    * [00:00 - 05:50] LIGO basics LIGO-India, International Pulsar Timing Array, Hulse–Taylor pulsar
    * [05:50 - 09:30] LIGO-India vs other detectors LIGO-India: A Planned Joint India-US Detector

    Advancing Human Knowledge: LIGO-India Part I

    Advancing Human Knowledge: LIGO-India Part I

    From Galileo to Einstein, humanity’s best minds have spent a considerable amount of time trying to understand the physical laws of our Universe. Now we’re testing the limits of our understanding by studying the most unique objects that the cosmos can provide us — Neutron Stars, Black Holes and Gravitational Waves. This requires the current generation of physicists to build analytical models, collaborate across domains and construct enormously complex experiments.
    Prof Debarati Chatterjee is one such physicist. In this part 1 of my conversation with her we cover her journey to becoming an astrophysicist and working at Inter-University Centre for Astronomy and Astrophysics (IUCCA). We also talk about the state of Gravitational Wave science in India, the creation & importance of IUCCA and then dig deeper into some of the key concepts needed to understand Gravitational Waves.
    In talking to Prof Chatterjee, it’s clear to see her passion for astrophysics and focus on being a skilled science communicator. I hope you enjoy listening to this conversation. Part 2 is coming soon!

Great, informative, and easy to listen to

This is a well researched podcast, and well presented. The material is very informative but not dense in any way. People who are somewhat familiar with space research, or even newly interested in it, will find it insightful.
