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.

A Quarter Century of Wind Spacecraft Discoveries
Reviews of Geophysics, Volume 59, Issue 2, June 2021., 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 ...

A search for runaway stars in 12 Galactic supernova remnants
Astronomische Nachrichten, Volume 342, Issue 3, Page 553-577, March 2021., 2021 Runaway stars can result from core‐collapse supernovae in multiple stellar systems. If the supernova disrupts the system, the companion is ejected with its former orbital velocity. A clear identification of a runaway star can yield the time and place of the explosion, as well as orbital parameters of the pre‐supernova binary system.

Magnetic Reconnection in the Space Sciences: Past, Present, and Future
Journal of Geophysical Research: Space Physics, Volume 125, Issue 2, February 2020., 2020 Abstract Magnetic reconnection converts, often explosively, stored magnetic energy to particle energy in space and in the laboratory. Through processes operating on length scales that are tiny, it facilitates energy conversion over dimensions of, in some cases, hundreds of Earth radii.

Advances in High Energy Physics, Volume 2026, Issue 1, 2026.This work examines the physical characteristics of charged, anisotropic compact spheres within the framework of f(R, ϕ, X) modified gravity. Starting from a static, spherically symmetric spacetime, we employ an Adler‐type ansatz for the temporal metric component gtt.

XMM‐Newton Observations of the Peculiar Be X‐Ray Binary A0538‐66
Astronomische Nachrichten, Volume 346, Issue 1, January 2025.ABSTRACT A0538‐66 is a neutron star/Be x‐ray binary located in the Large Magellanic Cloud and, since its discovery in the 70s, it showed a peculiar behavior that makes it a unique object in the high‐mass x‐ray binaries scene: the extremely eccentric orbit (e=0.72$$ e=0.72 $$), the short spin period of the neutron star (P=69$$ P=69 $$ ms), the episodes ...

Estimation of the detected background by the future gamma ray transient mission CAMELOT
Astronomische Nachrichten, Volume 340, Issue 7, Page 666-673, August 2019., 2019 Abstract This study presents a background estimation for the CubeSats Applied for MEasuring and LOcalising Transients (CAMELOT), which is a proposed fleet of nanosatellites for the all‐sky monitoring and timing‐based localization of gamma ray transients with precise localization capability at low Earth orbits.
