JWST/NIRSpec Reveals the Atmospheric Driver of Saturn's Variable Magnetospheric Rotation Rate
Abstract Past measurements of Saturn's upper atmosphere have allowed only a broad scale view of the temperature and ion density structures within the auroral region. However, Saturn's auroral currents include a planetary period current component that is produced by neutral atmospheric flows.

Abstract Jovian magnetospheric dynamics are often believed to be mainly controlled by internal elements such as Jupiter's strong and fast‐rotating magnetic moment and Io's abundant volcanic escape, as these internal elements are powerful enough to control the magnetospheric dynamics, contrary to the internal elements of the earth's magnetosphere.

t-channel dark matter models – a whitepaper
This report, summarising work achieved in the context of the LHC Dark Matter Working Group, investigates the phenomenology of t-channel dark matter models, spanning minimal setups with a single dark matter candidate and mediator to more complex ...

Imaging the Perpendicular Plasma Dynamics Driving a Discrete Auroral Arc
Abstract Measurements of motions and structuring in auroral luminosity are combined with magnetically connected plasma measurements from the Reimei spacecraft to image the perpendicular plasma dynamics active above a discrete auroral arc. It is demonstrated how the inversion of optical flow patterns specifies the potential structure above regions of ...

Galaxies are biased tracers of the underlying cosmic web, which is dominated by dark matter (DM) components that cannot be directly observed. Galaxy formation simulations can be used to study the relationship between DM density fields and galaxy ...

DART: A Dual Aperture Relativistic Electron Telescope for Smallsats
Abstract The precipitation of particles into the Earth's atmosphere is a primary loss mechanism of the radiation belt for which many unknowns remain. With the growing number of space mission concepts to solve them, less expensive alternatives such as CubeSats are being used.

Neutrino in Astrophysics and Cosmology
At first we introduce the Neutrino in the standard Model, then the Dirac and Majorana Masses. After introducing the See-Saw Mechanism, we discuss the neutrino oscillations and the neutrino in astrophysics and cosmology. We finish this paper with a brief summary of the neutrino experiments.

Abstract Variations in nighttime airglow at mid‐latitudes during geomagnetic disturbances reflect the propagation of atmospheric and plasma disturbances from polar heating as well as local chemical processes. However, their detailed mechanisms remain unclear.

First Coincident Radar and Optical Observations of a Meteor Radio Afterglow
Abstract It has been hypothesized that Meteor Radio Afterglows (MRAs) occur due to resonant transition radiation (RTR) where suprathermal electrons emit as they pass through electron density inhomogeneities in a turbulent plasma. Meteor trails are thought to produce suprathermal electrons through anion oxidation, which can be identified through meteor ...
