Halson's research helps solve the mystery of the creation of the universe

This year's Nobel Prize in Physics was won by the American scholar Halson, who successfully captured neutrinos from the universe in the Antarctic ice. Experts said that Halson's research helped the scientific community unravel the mystery of the creation of the universe. The Institute of Physics of Academia Sinica cooperated with the Antarctic "IceCube Neutrino Observatory" chaired by Halson to help develop open source software to analyze the data obtained by the IceCube Observatory.

Academia Sinica Institute of Physics joins team research

The Taiwan Science and Technology Media Center invited four domestic experts to explain Halson's contribution to astrophysics. Chen Pi-shen, Liang Cizhen Distinguished Chair Professor of Cosmology in the Department of Physics at National Taiwan University, said that the force of neutrinos is extremely weak. In the past, it was difficult for academic circles to prove that neutrinos exist outside the Milky Way. Halson set up the IceCube Neutrino Observatory in Antarctica and successfully captured neutrinos from the extremely distant universe. This allowed humans to receive unique cosmic information for the first time and allowed the academic community to better understand the creation mechanism of the universe.

Wang Zijing, a distinguished researcher at the Institute of Physics of Academia Sinica, pointed out that the study of neutrinos can be said to be the basis of astrophysics research, allowing the academic community to analyze phenomena through more waveband tools when observing the universe; Anatole, an assistant researcher at the Institute of Physics of Academia Sinica, has been a member of the team of the "IceCube Neutrino Observatory" hosted by Halson in Antarctica since 2009. After Tori joined Academia Sinica in 2021, he also became the head of IceCube Taiwan. He is mainly responsible for developing open source software and investing in hadron interaction model research, allowing the research team to more quickly and systematically evaluate the uncertainty of predictions, and allowing IceCube data analysis to provide a reliable comparison benchmark, including removing the earth's original neutrino background value.

Anatole visited Antarctica twice the year before last and last year. He said that Halson is humble and kind, and one of his most outstanding abilities is the ability to gather many powerful scientists to work together. He believed that Halson deserved the award. Huang Lijin, an adjunct associate professor at Chung Yuan University, published a paper on finding submillimeter wave signals through neutrino signals in June this year. The paper led Halson to write a special article praising this observation method as an important direction for future research.

Chen Pishen said that it is not easy to build an observatory in Antarctica. Since the Antarctic continent only has a three-kilometer-thick land ice layer that can eliminate other noise in the universe, Halson's team dug two holes there. It is not easy to place sensors behind a five-kilometer-deep ice cave, but Halson never takes credit and is willing to share the results.
