A Quarter Century of Wind Spacecraft Discoveries [PDF]
Rev Geophys, 2021 Abstract The Wind spacecraft, launched on November 1, 1994, is a critical element in NASA’s Heliophysics System Observatory (HSO)—a fleet of spacecraft created to understand the dynamics of the Sun‐Earth system. The combination of its longevity (>25 years in service), its diverse complement of instrumentation, and high resolution and accurate ...

Observations of Radio Magnetars with the Deep Space Network
Advances in Astronomy, 2019 The Deep Space Network (DSN) is a worldwide array of radio telescopes which supports NASA’s interplanetary spacecraft missions. When the DSN antennas are not communicating with spacecraft, they provide a valuable resource for performing observations of ...

The Zoo of Isolated Neutron Stars
Universe, 2023 In this brief review, I summarize our basic knowledge about different types of isolated neutron stars. I discuss radio pulsars, central compact objects in supernova remnants, magnetars, nearby cooling neutron stars (also known as the magnificent seven ...

R-Process with Magnetized Nuclei at Dynamo-Explosive Supernovae and Neutron Star Mergers
Universe, 2021 Nucleosynthesis at latge magnetic induction levels relevant to core-collapse supernovae and neutron star mergers is considered. For respective magnetic fields of a strength up to ten teratesla, atomic nuclei exhibit a linear magnetic response due to the ...

Evolution of Neutron Star Magnetic Fields
Universe, 2021 Neutron stars are natural physical laboratories allowing us to study a plethora of phenomena in extreme conditions. In particular, these compact objects can have very strong magnetic fields with non-trivial origin and evolution.

Anisotropic Behavior of S‐Wave and P‐Wave States of Heavy Quarkonia at Finite Magnetic Field
Advances in High Energy Physics, Volume 2023, Issue 1, 2023., 2023 We studied the effect of momentum space anisotropy on heavy quarkonium states using an extended magnetized effective fugacity quasiparticle model (EQPM). Both the real and imaginary part of the potential has been modified through the dielectric function by including the anisotropic parameter ξ.

Advances in High Energy Physics, Volume 2022, Issue 1, 2022., 2022 In this paper, we have investigated the density perturbations and cosmological evolution in the FLRW universe in the presence of a cosmic magnetic field, which may be assumed to mimic primordial magnetic fields. Such magnetic fields have sufficient strength to influence galaxy formation and cluster dynamics, thereby leaving an imprint on the CMB ...

Impacts of Ionospheric Ions on Magnetic Reconnection and Earth's Magnetosphere Dynamics
Reviews of Geophysics, Volume 59, Issue 3, September 2021., 2021 Abstract Ionospheric ions (mainly H+, He+, and O+) escape from the ionosphere and populate the Earth's magnetosphere. Their thermal energies are usually low when they first escape the ionosphere, typically a few electron volt to tens of electron volt, but they are energized in their journey through the magnetosphere.

Temporary Singularities and Axions: An Analytic Solution that Challenges Charge Conservation
Annalen der Physik, Volume 533, Issue 6, June 2021., 2021 Is charge conservation sacrosact? If so, why? Even when local charge conservation remains in force, the presence of a temporary singularity can give rise to surprising results. This work shows how global charge conservation can be broken after the combined appearance of both new charge and an axion‐like field from the singularity.
