A Dynamical and Kinematic Model of the Galactic Stellar Halo and Possible Implications for Galaxy Formation Scenarios [PDF]
The Astrophysical Journal, 1997 We re-analyse the kinematics of the system of blue horizontal branch field (BHBF) stars in the Galactic halo (in particular the outer halo), fitting the kinematics with the model of radial and tangential velocity dispersions in the halo as a function of galactocentric distance r proposed by Sommer-Larsen, Flynn & Christensen (1994), using a much ...

Plant Biotechnology Journal, Volume 23, Issue 11, Page 4910-4929, November 2025.Summary Orchard fruits such as pear and apple are important for ensuring global food security and agricultural economy as they not only provide essential nutrients, but also support biodiversity and ecosystem services. Breeders, growers and plant researchers constantly study desirable tree morphological features and floral characteristics to ensure ...

A review of multiscale numerical modeling of rock mechanics and rock engineering
Deep Underground Science and Engineering, Volume 4, Issue 3, Page 382-405, September 2025.Multiscale numerical methods of rock mechanics and rock engineering are reviewed, and the review results show that more attention should be paid to the development of an advanced constitutive model in addition to numerical techniques themselves. Abstract Rock is geometrically and mechanically multiscale in nature, and the traditional phenomenological ...

Structure and dynamics of galaxies with a low surface-brightness disc - I. The stellar and ionized-gas kinematics [PDF]
Monthly Notices of the Royal Astronomical Society, 2008 (abridged) Photometry and long-slit spectroscopy are presented for a sample of 6 galaxies with a low surface brightness stellar disc and a bulge. The stellar and ionised-gas kinematics were measured along the major and minor axis in half of the sample galaxies, whereas the other half was observed only along two diagonal axes. Spectra along two diagonal

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 16, 28 August 2025.Abstract In this study, we have investigated short‐period (< ${< } $1 hr) atmospheric gravity waves (AGWs) in the Arctic mesosphere‐lower thermosphere (MLT) region during January of 2014, 2015, and 2016. We used OH (3,1) band emission data from the Advanced Mesospheric Temperature Mapper (AMTM) at the Arctic Lidar Observatory for Middle Atmosphere ...

Two Micron‐Size Dark Dimensions
Fortschritte der Physik, Volume 73, Issue 8, August 2025.Abstract Two extra dimensions of micron scale might simultaneously address the gauge and cosmological hierarchy problems. In this paper various observational bounds in scenarios with one and two large extra dimensions are examined, to see if they are compatible with the micron scale.

Shell galaxies: kinematical signature of shells, satellite galaxy disruption and dynamical friction
, 2013 Stellar shells observed in many giant elliptical and lenticular as well as a few spiral and dwarf galaxies presumably result from radial minor mergers of galaxies. We show that the line-of-sight velocity distribution of the shells has a quadruple-peaked shape.

From nearby to distant galaxies: kinematical and dynamical studies
, 2009 Kinematical studies of low and high redshift galaxies enables to probe galaxy formation and evolution scenarios. Integral field spectroscopy is a powerful tool to study with accuracy nearby galaxies kinematics. Recent observations also gives a new 2D vision of high redshift galaxies kinematics.
