KINEMATICS OF STELLAR POPULATIONS IN POSTSTARBURST GALAXIES [PDF]

The Astrophysical Journal, 2015
Post-starburst galaxies host a population of early-type stars (A or F), but simultaneously lack indicators of ongoing star formation such as OII emission. Two distinct stellar populations have been identified in these systems: a young post-starburst population superimposed on an older host population.

How Do the Functional Resemblance Structure and Its Component‐Dependence Change Among the Successional Stages in Degraded Karst Forests?

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.

Late-type galaxies observed with SAURON. Two-dimensional stellar and emission-line kinematics of 18 spirals [PDF]

, 2005
We present the stellar and gas kinematics of a sample of 18 nearby late-type spiral galaxies (Hubble types ranging from Sb to Sd), observed with the integral-field spectrograph SAURON at the 4.2-m William Herschel Telescope.

OrchardQuant‐3D: combining drone and LiDAR to perform scalable 3D phenotyping for characterising key canopy and floral traits in fruit orchards

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 ...

Mapping the Stellar Kinematics in the Central 240 pc of M87 with the James Webb Space Telescope

The Astrophysical Journal
The 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.

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

A Gemini/GMOS Study of Intermediate Luminosity Early-Type Virgo Cluster Galaxies. I. Globular Cluster and Stellar Kinematics

, 2015
We present a kinematic analysis of the globular cluster systems and diffuse stellar light of four intermediate luminosity (sub-$L^{\ast}$) early-type galaxies in the Virgo cluster based on Gemini/GMOS data.

Modern Techniques in Galaxy Kinematics: Results from Planetary Nebula Spectroscopy [PDF]

Symposium - International Astronomical Union, 2003
We have observed planetary nebulae (PNe) in several early-type galaxies using new techniques on 4- to 8-meter-class telescopes. We obtain the first large data sets (≳ 100 velocities each) of PN kinematics in galaxies at ≳ 15 Mpc, and present some preliminary dynamical results.

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 ...

The AURORA Survey: Tracing Galactic Outflows at z ≳ 2.5 with JWST/NIRSpec Near-ultraviolet Absorption Lines

The Astrophysical Journal
We 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.
