Mapping the Stellar Kinematics in the Central 240 pc of M87 with the James Webb Space Telescope
The Astrophysical JournalThe supermassive black hole (SMBH) in the giant elliptical galaxy M87 is one of the most well studied in the local Universe, but the stellar- and gas-dynamical SMBH mass measurements disagree.

Scandinavian Journal of Medicine &Science in Sports, Volume 36, Issue 2, February 2026.ABSTRACT During gait, the temporal patterns of stride‐to‐stride fluctuations and muscle activation exhibit similar responses. This study examined if increasing task demands such as fatigued high intensity running affects this relationship. Eleven experienced runners completed two 400‐m runs (R1, R2) with a 3‐min break to induce fatigue.

The Astrophysical JournalWe probe galactic-scale outflows in star-forming galaxies at z ≳ 2.5 drawn from the JWST/NIRSpec AURORA program. For the first time, we directly compare outflow properties from the early Universe to the present day using near-UV absorption lines.

Projection effects in barred galaxies cause the wrong interpretation of radial flows
Astronomy & AstrophysicsGalaxy disks in rotation are sometimes the site of radial flows, especially in their gas component. It is important to estimate the outflows, due to active galactic nucleus or supernovae feedback, or the inflows, due to bar gravity torques.

Distribution and Kinematics of Classical Cepheids in the Galactic Outer Ring
Open Astronomy, 2015 The existence of an outer ring in the Galaxy can explain the kinematics of OB associations in the Perseus and Sagittarius stellar-gas complexes. Moreover, it can also explain the orientation of the Carina arm with respect to the major axis of the bar. We

IET Biometrics, Volume 2026, Issue 1, 2026.Human activity recognition (HAR) is a core technology in fields such as smart healthcare and human–computer interaction, which aims to classify daily activities (e.g., walking and running) based on sensor data automatically. While existing approaches achieve high accuracy in controlled laboratory settings, they often perform poorly in real‐world ...

Kinematics of Nuclei of Sc Galaxies [PDF]
Highlights of Astronomy, 1980 For a sample of 21 Sc galaxies with a wide range of luminosities, of radii, and of masses, W. K. Ford and I have obtained spectra and determined rotation curves. By their kinematical behavior in their central regions, the Sc’s can be separated into two groups. Some galaxies, generally small and of low luminosity, have shallow central velocity gradients,

Ecology and Evolution, Volume 15, Issue 12, December 2025.This study was conducted in an extremely heterogeneous karst forest ecosystem. We found asynchronous changes in taxonomic and functional dissimilarities along the succession pathway and the functional redundancy dominated the functional resemblance structure.
