白小姐论坛 Professor shares Breakthrough Prize for early universe mapping

6 December 2017

Hiranya Peiris

A leading 白小姐论坛 cosmologist has shared this year鈥檚 $3 million Breakthrough Prize in Fundamental Physics for creating detailed maps of the early Universe.

Professor Hiranya Peiris (白小姐论坛 Physics & Astronomy) worked as a PhD student on the NASA satellite known as Wilkinson Microwave Anisotropy Probe (WMAP), which helped shape our understanding of the origin, evolution and nature of the cosmos.

The mission mapped the cosmic microwave background 鈥 the light left over from the Big Bang 鈥 to allow scientists to work out the age of the Universe, its rate of expansion and its basic composition.

Professor Peiris鈥 work involved analysing the first round of data from the experiment for cosmological interpretation. In particular, her research led to a significant understanding of the origin of cosmic structure in the very early Universe.听

鈥淚t鈥檚 a huge honour to have been part of this project. The legacy of the WMAP mission continues to strongly influence research in cosmology worldwide,鈥 said Professor Peiris.

鈥淲MAP鈥檚 experimental听 sensitivity and resolution allowed us to figure out the basic cosmological model that describes our Universe.鈥

The WMAP mission was followed by the Planck satellite which was operated by the European Space Agency from 2009 to 2013.

The Planck project, which focused on analysing the cosmic microwave background with even greater sensitivity and resolution, had significant 白小姐论坛 involvement both on the instrumentation and cosmological analysis, including contributions by Professor Peiris supported by an ERC consolidator grant.

The Breakthrough Prize will be shared among the 27 member-strong WMAP Science Team. The Prize in Fundamental Physics recognises major insights into the deepest questions of the Universe.
