IUCAA Researchers Use Mira Stars to Refine Universe's Expansion Rate

Researchers at IUCAA, led by Anupam Bhardwaj, have used Mira stars for the first time to measure the Hubble constant with 3.7% accuracy. This new method provides an independent check on existing measurements of the universe's expansion rate. The study is crucial for addressing the 'Hubble tension,' a significant discrepancy in cosmological measurements, and was published in the Astrophysical Journal.
