Geomagnetic effects on cosmic ray propagation under different conditions for Buenos Aires and Marambio, Argentina [PDF]
, 2014 The geomagnetic field (Bgeo) sets a lower cutoff rigidity (Rc) to the entry of cosmic particles to Earth which depends on the geomagnetic activity. From numerical simulations of the trajectory of a proton using different models for Bgeo (performed with ...

Kobayashi-Hitchin correspondence for tame harmonic bundles II
, 2008 Let $X$ be a smooth projective complex variety with an ample line bundle $L$, and let $D$ be a simple normal crossing divisor. We establish the Kobayashi-Hitchin correspondence between tame harmonic bundles on $X-D$ and $\mu_L$-stable parabolic $\lambda$-

Space Weather, Volume 24, Issue 4, April 2026.Abstract The South Atlantic Anomaly (SAA) in Earth's radiation belt is a critical region that poses significant threats to the safety of Space Stations. This region harbors a high concentration of energetic particles that can penetrate Space Stations, thereby affecting onboard components and posing risks to astronauts.

Report on the magnetic survey in Slovakia for the 2014.5 epoch
Contributions to Geophysics and Geodesy, 2016 The models of the distribution of the elements of the geomagnetic field must be updated regularly. For this purpose geomagnetic measurements have to be carried out repeatedly at geomagnetic observatories as well as at temporary observation points.

Evaluation of candidate geomagnetic field models for IGRF-11 [PDF]
Earth, Planets and Space, 2010 The eleventh generation of the International Geomagnetic Reference Field (IGRF) was agreed in December 2009 by a task force appointed by the International Association of Geomagnetism and Aeronomy (IAGA) Division V Working Group V-MOD. New spherical harmonic main field models for epochs 2005.0 (DGRF-2005) and 2010.0 (IGRF-2010), and predictive linear ...

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.Abstract We demonstrate the presence of the oldest identifiable marine magnetic anomalies in the Phoenix lineations of the western Pacific based on careful assessment of new data. Recently acquired sea surface magnetic anomalies and multichannel seismic profiles confirm magnetic signals recorded within the Middle‐Jurassic to Early Cretaceous basement ...
