An international team of researchers led by Masamune Oguri at Kavli IPMU and Naohisa Inada at Nara National College of Technology conduced an unprecedented survey of gravitationally lensed quasars, and used it to measure the expansion history of the universe. The result provides strong evidence that the expansion of the universe is accelerating. There were several observations that suggested the accelerated cosmic expansion, including distant supernovae for which the 2011 Nobel Prize in Physics was awarded. The team’s result confirms the accelerated cosmic expansion using a completely different approach, which strengthens the case for dark energy. This result will be published in The Astronomical Journal.

Fang Lizhi, a major voice for human rights and democracy and a pioneering scientist in his native China, continued to advance the field of astrophysics at the UA for more than 20 years before he died last week.
Human rights activist Fang Lizhi, who died last week at age 76, had been a professor in the University of Arizona department of physics and an adjunct professor with the UA’s Steward Observatory for more than 20 years, where he made highly regarded contributions to astrophysics.
Fang was world renowned for his outspoken and active role in promoting human rights in his native China.
Considered an “undesirable element” by the Chinese government, Fang was dismissed from the Chinese nuclear program and reassigned in 1958 to the University of Science and Technology of China, or USTC, which is regarded as China’s equivalent of the Massachusetts Institute of Technology.
