The joint Indo – UK Newton – Bhabha: Open Data Workshop was held at IUCAA during December 4-6, 2019. The main goal was to provide an opportunity for students, postdocs and other academics interested in gravitational waves, and who would look forward to do science with the LIGO-India Observatory. There were 60 participants. The resource persons were the experts from the UK, such as Giles Hammond, Martin Hendry, Chris Messenger, and Ik Siong Heng. There were several Indian and f o r e i g n o t h e r e x p e r t s i n e x p e r i m e n t a t i o n /instrumentation as well as those from gravitational wave science and data analysis. The format of the workshop included a few common sessions and many parallel sessions. For the Open Data part of the workshop, there were hands-on tutorial sessions on Basics of GW data, Application of deep learning to classify BBH signal vs. Noise and a non-standard yet improved data analysis pipeline. In parallel, we had the experimental sessions, where the groups working on LIGO coatings research and cryogenic suspension technology talked about the stringent requirements and timelines that they face with the next generation interferometric detectors. They pointed out key research longitudinal separation, can use mutually agreed telescope time sharing to their advantage. 3. Both countries have their expertise on astronomy instrumentation(astro-engineering), and this can be shared; e.g., India can provide know-how or build optical/radio instruments for the respective telescope and similarly fromChilean side. 4. In areas of space, joint small satellites development and launch by ISRO to be pursued. 5. India has an established balloon programme for astronomy, and can provide common collaboration in terms of building balloon based payloads and launches, etc. 6. Explore interchange of staff/students between participating institutions, or between these and universities, taking advantage of the existing regulatory frameworks allowing these mechanisms. If possible, executeMoUs in the same. 7. TheAstronomical Society of India (ASI) will make a working committee to pursue the various aspects of this dialogue's action items, and it will also formulate an expression of interest (EoI), which will be circulated to theASI members for their response. The dialogue was coordinated at IUCAA by Ranjan Gupta. Newton – Bhabha: Open Data (Indo – UK) Workshop No. 121 - January 2020 6
