重力波の検出 - 第104回丸の内セミナー

Explore gravitational wave detection in this lecture segment from the 104th Kyoto University Marunouchi Seminar, where Professor Kunihito Ioka from the Yukawa Institute for Theoretical Physics discusses the groundbreaking direct detection of gravitational waves on September 14, 2015 - exactly 100 years after Einstein's theory of general relativity. Learn how the merger of two black holes revealed an entirely new view of the universe, demonstrating that black holes are abundant throughout space. Discover the historical significance of the August 17, 2017 detection of gravitational waves from neutron star mergers, accompanied by gamma-ray bursts and electromagnetic waves across all wavelengths, marking the beginning of the multi-messenger astronomy era. Examine the controversial findings around these unusually dim gamma-ray bursts and understand the off-axis jet model proposed to explain these observations, including recent supporting evidence that validates the 40-year-old hypothesis connecting neutron star mergers to gamma-ray bursts.
