Kavli Affiliate: Giorgio Gratta | First 5 Authors: Zachary Bogorad, Peter W. Graham, Giorgio Gratta, , | Summary: Significant effort has been devoted to searching for new fundamental forces of nature. At short length scales (below approximately 10 nm), the strongest experimental constraints come from neutron scattering from individual nuclei in gases. The leading experiments […]
Kavli Affiliate: Alexander P. Ji | First 5 Authors: Yupeng Yao, Alexander P. Ji, Sergey E. Koposov, Guilherme Limberg, | Summary: Very metal-poor stars ($rm[Fe/H] < -2$) in the Milky Way are fossil records of early chemical evolution and the assembly and structure of the Galaxy. However, they are rare and hard to find. Gaia […]
Kavli Affiliate: Lijing Shao | First 5 Authors: Zexin Hu, Xueli Miao, Lijing Shao, , | Summary: Tests of gravity are important to the development of our understanding of gravitation and spacetime. Binary pulsars provide a superb playground for testing gravity theories. In this chapter we pedagogically review the basics behind pulsar observations and pulsar […]
Kavli Affiliate: Yuji Tachikawa | First 5 Authors: Philip Boyle Smith, Ying-Hsuan Lin, Yuji Tachikawa, Yunqin Zheng, | Summary: We classify two-dimensional purely chiral conformal field theories which are defined on two-dimensional surfaces equipped with spin structure and have central charge less than or equal to 16, and discuss their duality webs. This result can […]
Kavli Affiliate: Scott A. Hughes | First 5 Authors: Viktor Skoupý, Georgios Lukes-Gerakopoulos, Lisa V. Drummond, Scott A. Hughes, | Summary: This work provides gravitational wave energy and angular momentum asymptotic fluxes from a spinning body moving on generic orbits in a Kerr spacetime up to linear in spin approximation. To achieve this, we have […]

Kavli Affiliate: Debora Sijacki | First 5 Authors: Callum Witten, Nicolas Laporte, Sergio Martin-Alvarez, Debora Sijacki, Yuxuan Yuan | Summary: A major event in cosmic history is the genesis of the first starlight in our Universe, ending the ”Dark Ages”. During this epoch, the earliest luminous sources were enshrouded in neutral and pristine gas, which […]
Kavli Affiliate: Roberto Maiolino | First 5 Authors: Callum Witten, Nicolas Laporte, Sergio Martin-Alvarez, Debora Sijacki, Yuxuan Yuan | Summary: During the epoch of reionisation the first galaxies were enshrouded in pristine neutral gas, with one of the brightest emission lines in star-forming galaxies, Lyman-$alpha$ (Ly$alpha$), expected to remain undetected until the Universe became ionised. […]
Kavli Affiliate: T. Higuchi | First 5 Authors: S. Imajo, H. Akatsuka, K. Hatanaka, T. Higuchi, G. Ichikawa | Summary: Metal tubes plated with nickel-phosphorus are used in many fundamental physics experiments using ultracold neutrons (UCN) because of their ease of fabrication. These tubes are usually polished to a average roughness of 25-150 nm. However, […]
