The Pulsating Pulsar Magnetosphere [PDF]
Following the basic principles of a charge separated pulsar magnetosphere \citep{goldreich1969}, we consider the magnetosphere be stationary in space, instead of corotating, and the electric field be uploaded from the potential distribution on the pulsar surface, set up by the unipolar induction.

Magnetospheric "anti-glitches" in magnetars [PDF]
We attribute the rapid spindown of magnetar 1E 2259+586 observed by Archibald et al. (2013), termed the "anti-glitch", to partial opening of the magnetosphere during the X-ray burst, followed by changes of the structure of the closed field line region. To account for the observed spin decrease during the X- ray flare all that is needed is the transient

Long-term evolution of the force-free twisted magnetosphere of a magnetar [PDF]
We study the long-term quasi-steady evolution of the force-free magnetosphere of a magnetar coupled to its internal magnetic field. We find that magnetospheric currents can be maintained on long timescales of the order of thousands of years. Meanwhile, the energy, helicity and twist stored in the magnetosphere all gradually increase over the course of ...

Identifying Magnetotail Jet Front Signatures in a 3D + 3V Global Hybrid‐Vlasov Simulation
Abstract Magnetic reconnection in Earth's magnetotail is thought to create bursty bulk flows (BBFs), short‐lived plasma bulk velocity enhancements in the magnetotail's central plasma sheet (CPS) region. Closely related to BBFs are dipolarization fronts (DFs), sudden increases in Bz ${B}_{z}$, the magnetic field component aligned with Earth's magnetic ...

Unveiling the Gannon Storm: How Ground‐Based Magnetometers Mapped Its Global Impact
Abstract The Gannon Storm, also known as the Mother's Day Storm of May 2024, ranks among the most intense geomagnetic disturbances of the space age, triggered by a powerful interplanetary coronal mass ejection. Leveraging data from over 100 globally distributed magnetic observatories, this study provides a detailed analysis of its ground‐level impacts,

This book belongs to a series of online books summarizing the recent state Topological Geometrodynamics (TGD) and its applications. TGD can be regarded as a unied theory of fundamental interactions but is not the kind of unied theory as so called GUTs constructed by graduate students at seventies and eighties using detailed recipes for how to reduce ...

Abstract In early May 2024 ∼ ${\sim} $6 Coronal Mass Ejections were launched toward the Earth in short succession. This triggered the G5 “Gannon” geomagnetic storm lasting from ∼ ${\sim} $17 UT on 10 May 2024 to ∼ ${\sim} $9 UT on 12 May 2024.

Space activities in subarctic Sweden are predicated on older infrastructures of underground resource extraction. The ongoing expansion of the country's rocket launch site outside Kiruna relies on the Swedish state's historical construction of the region as a resource frontier.

The high-energy tail of energetic electron precipitation: case studies
Precipitating plasma sheet, ring current, and radiation belt electrons will affect the ionization level and composition of the neutral atmosphere. Knowledge gaps remain regarding the frequency, intensity, and energy spectrum of the Medium Energy Electron
