Kavli Affiliate: T. Higuchi | First 5 Authors: B. Algohi, B. Algohi, , , | Summary: We report the first results on ultracold neutron production from a new spallation-driven superfluid $^4$He (He-II) source at TRIUMF, which is being prepared for a new, precise measurement of the neutron electric dipole moment. A total of $(9.3 pm […]
Kavli Affiliate: Menno Witter | Authors: Eirik S. Nilssen, Bente Jacobsen, Thanh P. Doan, Paulo J.B. Girao and Menno P. Witter | Summary: ABSTRACT The functionally different lateral entorhinal cortex (LEC) and medial entorhinal cortex (MEC) are strongly interconnected. The role of this interconnectivity in view of their functional differences is not known. Here we […]
Kavli Affiliate: Andrey Kravtsov | First 5 Authors: Simon May, Simon May, , , | Summary: The particle mass of dark matter (DM) was previously constrained using kinematics of ultra-faint dwarf galaxies to $m > 3 times 10^-19,mathrmeV$. This constraint, which excludes the "fuzzy" range of ultra-light dark matter from comprising all of the DM, […]
Kavli Affiliate: Leon Balents | First 5 Authors: Feng Chen, Feng Chen, , , | Summary: Moir’e materials provide exciting platforms for studying the interplay of strong electronic correlation and large magnetic flux effects. We study the lightly doped Hofstadter-Hubbard model on a triangular lattice through large-scale density matrix renormalization group and determinantal quantum Monte […]
Kavli Affiliate: Giorgio Gratta | First 5 Authors: Albert Nazeeri, Albert Nazeeri, , , | Summary: Mechanical modulation of recoilless nuclear transitions allows the dynamic control of gamma-ray emission and absorption. Accessing modulation frequencies well above the nuclear linewidth enables coherent manipulation of the nuclear response. Here we demonstrate such control by coupling a film […]
Kavli Affiliate: Luis C. Ho | First 5 Authors: Reena Chaudhary, Reena Chaudhary, , , | Summary: We investigate the origin of intervening cool MgII absorption detected in the spectra of background quasars and the nature of associated galaxies across a broad redshift range of $0.3 le z le 1.6$. Using nebular [O II] $lambdalambda$3727,3729 […]
Kavli Affiliate: Salman Habib | First 5 Authors: Andrew Ferguson, Andrew Ferguson, , , | Summary: This community paper developed out of the NSF Workshop on the Future of Artificial Intelligence (AI) and the Mathematical and Physics Sciences (MPS), which was held in March 2025 with the goal of understanding how the MPS domains (Astronomy, […]

Kavli Affiliate: Alexander P. Ji | First 5 Authors: Nathan R. Sandford, Nathan R. Sandford, , , | Summary: We combine new spectroscopic observations of the ultra faint dwarf galaxy (UFD) Bo"otes I (Boo I) from the Southern Stellar Stream Spectroscopic Survey ($S^5$) with $sim$15 years of archival spectroscopic data to create the largest sample […]
Kavli Affiliate: Susan E. Clark | First 5 Authors: Diego Maglione, Diego Maglione, , , | Summary: Magnetic fields are a fundamental part of the interstellar medium (ISM) and remain a challenge for building a comprehensive understanding of galactic properties. Their study requires far-infrared polarimetric observations, which provide an unrivaled probe of the dynamics, magnetization, […]
