Cosmoparticle Physics -the Challenge for the Millenium

, 2003
Cosmoparticle physics is the natural result of development of mutual relationship between cosmology and particle physics. Its prospects offer the way to study the theory of everything and the true history of the Universe, based on it, in the proper ...

Ion Energization and Acceleration Associated With Foreshock Bubbles: Results From a Hybrid‐Vlasov Simulation and MMS Observations

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract Foreshock Bubbles (FBs) are large‐scale transient structures found in Earth's foreshock region and are associated with foreshock‐discontinuity interaction. FBs play a significant role in accelerating and energizing plasma through various mechanisms.

Loading Non‐Maxwellian Velocity Distributions in Particle Simulations

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract Numerical procedures for generating non‐Maxwellian velocity distributions in particle simulations are presented. First, Monte Carlo methods for the (r,q) $(r,q)$ distribution that generalizes flattop and Kappa distributions are discussed. Then, two rejection methods for the regularized Kappa distribution are presented, followed by a comparison

Probing for Lorentz Invariance Violation in Pantheon Plus Dominated Cosmology

Universe
The Hubble tension in cosmology is not showing signs of alleviation and thus, it is important to look for alternative approaches to it. One such example would be the eventual detection of a time delay between simultaneously emitted high-energy and low ...

MMS Observation of Trapping of Electrons by Chorus Waves Inside a Magnetic Hole

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract We present an event of chorus waves embedded within a magnetic hole (MH) in the Earth's magnetosheath, observed by the Magnetospheric Multi‐Scale (MMS) mission on 1 March 2016. Unlike conventional cases where chorus waves are typically detected near the center of a magnetic depression, in this event lower‐band chorus waves appear predominantly

Thermospheric Energy and Heating Due To Upward Propagating and in Situ Generated Tides During Solar Cycle 24

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract We investigate vertical and horizontal energy transport and associated heating in the thermosphere due to both upward propagating and in situ generated migrating and nonmigrating diurnal and semidiurnal tides over the solar cycle 24 (2009–2019).

Cosmological and Astrophysical Parameter Inference from Stacked Galaxy Cluster Profiles Using CAMELS-zoomGZ

The Astrophysical Journal
We present a study on the inference of cosmological and astrophysical parameters using stacked galaxy cluster profiles. Utilizing the CAMELS-zoomGZ simulations, we explore how various cluster properties—such as X-ray surface brightness, gas density ...

Simultaneous Observations of Electron Phase Space Density Variations in the Geostationary Orbit by GK2A, GOES‐16, and GOES‐17

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract This study presents simultaneous measurements of electron phase space density (PSD) gradients in geostationary orbit using data from GK2A, GOES‐16, and GOES‐17. By leveraging a three‐satellite configuration, we provide statistical results of PSD gradient estimation in invariant coordinates.

Extending the Wave Telescope Technique to Larger Numbers of Spacecraft Obtaining Robust Spatial Power Spectra

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract The wave telescope is an analysis technique for multi‐point spacecraft data that estimates power spectra in reciprocal position space (k $k$‐space). It has been used to reveal the spatial properties of waves and fluctuations in space plasmas. Originally designed as an analysis tool for 4 spacecraft constellations, new multi‐scale missions such
