    Searching for dark torsion signatures at LIGO in Nieh–Yan teleparallel chiral gravitational waves and Chern–Simons invariants by L. C. Garcia de Andrade

    Published 2024-12-01
    “…In particular, nonhomogeneous and nonuniform chiral chemical potential generates GWs and dark torsion from primordial magnetic fields. It is shown that pulsar sources for GWs bathing the surface of the Earth on a contortion background of $$10^{-15}\,\textrm{s}^{-1}$$ 10 - 15 s - 1 possess amplitudes well within the parameters of LIGO capabilities of amplitudes on the order of $$10^{-22}$$ 10 - 22 . …”

    Assessment of the Weimer Geomagnetic Perturbation Model for High‐Latitude Positioning and Navigation by S. Califf, M. Nair, D. Weimer, N. Zachman, B. Poedjono

    Published 2024-10-01
    “…Abstract The Geomagnetism Group at the National Centers for Environmental Information (NCEI), in collaboration with the Cooperative Institute for Research in Environmental Sciences (CIRES), along with various government and industry partners, specializes in developing and providing access to Earth's internal magnetic field models. These models are crucial for applications such as compass navigation and wellbore positioning, offering reference values for the geomagnetic field (total field, dip or inclination, and declination) at any location across the Earth. …”

    Observation and Simulation of Chorus Waves in Middle Magnetotail (r > 20 RE) by W. D. Fu, H. S. Fu, Y. F. Wu, X. Tao, Y. Yu, W. Z. Zhang, J. B. Cao

    Published 2025-01-01
    “…Abstract Whistler‐mode chorus waves, characterized by repetitive frequency‐chirping elements, have traditionally been considered to be confined to near‐planet dipolar magnetic fields. In contrast to this long‐held belief, here we present the first observation of whistler‐mode chorus waves in the middle magnetotail beyond 20 RE from Earth, based on MMS measurements. …”
