IUCAA Brochure 2024

These results pave the way for new observations from the upcoming Vera C. Rubin observatory, where IUCAA is an international partner. With an 8.4-meter mirror and the largest camera ever built for astronomy and astrophysics, the observatory will conduct a ten-year survey of the Southern Hemisphere sky from its site in Chile. It will help us discover about 20 billion galaxies and a similar number of stars, to further our understanding of the structure and evolution of theUniverse distribution in the Universe and its clumpiness. This clumpiness can be predicted in the standard cosmological model based on observations of the earliest light in the Universe coming from the cosmic microwave background. The new result seems lower than this prediction at more than 99 percent confidence and could indicate a breakdown of the standard cosmological model.
