Understanding Galaxy Formation and Evolution
The central problem addressed in this podcast episode is understanding how galaxies form and evolve. Galaxies are ensembles of stars that also contain gas, which stars form from. However, this process is complex due to the presence of massive black holes at the center of galaxies emitting significant energy and disrupting star formation. To study galaxy evolution, the team is using the MIRCAT Telescope in South Africa to collect data on millions of galaxies. The goal is to process and analyze 1.6 petabytes of data gathered over three years to gain insights into galaxy formation and evolution.
Technological Challenges in Processing Large Data Volumes
The podcast highlights the technological challenges in processing the vast amount of data collected by the MIRCAT Telescope. The team initially faced issues with handling the petabyte-scale data and building a robust pipeline that could support the complex analysis requirements of astrophysics. They needed a system that could handle data processing efficiently while being adaptable to different stages of pipeline configuration. They prototyped and tested the pipeline using both simulated and real data from existing telescopes to ensure its effectiveness. By adopting best software engineering practices and working closely with experts, they developed a system capable of handling the massive data volume and producing reliable results for scientific analysis.
The Need for Collaboration and Prototyping
The collaboration between technology experts and scientists played a crucial role in the success of the project. The team recognized early on that traditional methods would not be sufficient to process the large volume of data. They needed experts in software engineering, as well as astronomy, to design and build a robust pipeline. By prototyping and testing the system with simulated and real data, they were able to identify and address potential issues. The collaboration allowed for the development of a customizable pipeline that scientists could configure and run, while also ensuring the reliability and efficiency of the system.
Scientific Discoveries and the Future of the Pipeline
Throughout the pipeline's development and data processing, several significant scientific discoveries have been made. The team detected hydroxyl molecules in galaxies, validating our understanding of the conversion of gas into stars. They also found recombination lines, furthering our understanding of ionization processes in galaxies and opening up new research possibilities. The success of the pipeline and the scientific discoveries made so far have provided confidence in its capabilities. Looking to the future, the pipeline's technology can serve as inspiration for building science platforms at a larger scale, reducing cognitive burdens for researchers and enabling reproducibility of results. The collaboration between technology and science will continue to drive advancements in both fields.
Radio astronomy — a subfield of astronomy that studies the sky using radio frequencies — is data-intensive. That poses a challenge for radio astronomers: building and then communicating scientific insights requires significant processing and analytical work. Thoughtworks has been working with Dr. Neeraj Gupta from the Inter-University Centre for Astronomy and Astrophysics (IUCAA) in India to develop solutions to these challenges, including a data processing pipeline, a collaborative platform for analysis and a digital catalog for publishing and communicating research.
In this episode of the Technology Podcast Dr. Gupta joins Justin Jose of Thoughtworks India's Engineering for Research (E4R) team as they speak to hosts Rebecca Parsons and Prem Chandrasekaran about their work together. Dr. Gupta explains the benefits of Thoughtworks work from an astronomer perspective, while Justin highlights the challenges of building software solutions in a highly specialized domain.
