The Dynamics of the Dwarf Elliptical Galaxy FS 76: Bridging the Kinematic Dichotomy between Elliptical and Dwarf Elliptical Galaxies [PDF]

The Astrophysical Journal, 2001
We present major- and minor-axis kinematics out to ˜2 half-light radii for the bright (MB = -16.7) dwarf elliptical galaxy (dE) FS 76, a member of the NGC 5044 group. Its velocity dispersion is 46 ‘ 2 km s-1 in the center and rises to 70 ‘ 10 km s-1 at half-light radius. Beyond 1Re, the dispersion starts to fall again.

Validation of a novel instrumented hoof boot with pressure sensors using force plate gait kinetics in horses at walk and trot

Equine Veterinary Journal, EarlyView.
Abstract Background Force plates (FP) are considered the gold standard for quantitative equine gait evaluation but are limited to experimental use. An instrumented hoof boot (IHB) with pressure sensors and an inertial measurement unit would allow clinicians to objectively assess kinetic parameters and gait symmetry.

Kinematics and dynamics of the luminous infrared galaxy pair NGC 5257/58 (Arp 240) [PDF]

Astronomy & Astrophysics, 2018
Context. Encounters between galaxies modify their morphology, kinematics, and star formation history. The relation between these changes and external perturbations is not straightforward. The great number of parameters involved requires both the study of large samples and individual encounters where particular ...

Exploring the Potential of Unmanned Aerial System‐Based Topographic Indices Maps to Evaluate Storm Drain Positioning

Journal of Flood Risk Management, Volume 19, Issue 4, December 2026.
ABSTRACT Urbanisation, climate uncertainty, and limited city budgets have heightened the need for efficient urban drainage management. While advanced hydrodynamic models assess the performance of drainage networks, they are computationally intensive, time‐consuming, and expensive.

Stäackel-type Dynamic Model of the Galaxy Based on Maser Kinematic Data

Open Astronomy, 2016
Abstract A dynamic model of the Galaxy is constructed based on kinematic data for masers with trigonometric parallaxes. Maser data is used to compute the model potential in the Galactic plane. The potential is then generalized to three dimensions assuming the existence of a third quadratic integral of motion. The resulting Galactic model

Influence of Dynamical Friction on the Unstable Manifolds of Lagrange Points in Barred Galaxies

Astronomische Nachrichten, Volume 347, Issue 8, October 2026.
ABSTRACT Some time ago the idea has been proposed that rings and spirals in barred galaxies are shaped by the unstable manifolds of the Lagrange points sitting near the ends of the bar. The topic of the present article is an investigation of whether the numerical support for this suggestion can be improved by the inclusion of dynamical friction into ...

Integrated Digital Garment Modeling and Monte Carlo Simulation of a Water‐Based Radiation Protection Vest for Spaceflight Radiation Hazards

Space Weather, Volume 24, Issue 10, October 2026.
Abstract As crewed space missions set course for the Moon and beyond, astronauts will experience prolonged exposure to Galactic Cosmic Rays (GCR) and potentially intense Solar Proton Events (SPEs), both of which pose significant short‐ and long‐term health risks.

Type‐III Solar Radio Bursts at Mars: A 16.5‐Year Catalog From Mars Express‐MARSIS at 0.1–5.5 MHz

Space Weather, Volume 24, Issue 10, October 2026.
Abstract The most intense radio feature in the Solar System are the solar Type‐III radio bursts, which are associated with electron beams that propagate along open magnetic field lines. Although solar radio bursts have been studied since the 1940s, observations remain mainly restricted within 1 AU.

Collisionless Shocks: Contemporary State After Three Quarters of a Century of Research

Reviews of Geophysics, Volume 64, Issue 3, September 2026.
Abstract The collisionless shock research started in the late 1950s. Since then, plenty of data have been accumulated due to the large number of missions in the heliosphere, providing in situ measurements of the fields and particles. The quality of these measurements has vastly improved, especially in the last two decades.
