Near-surface velocity inversion and modeling method based on surface waves in petroleum exploration: a case study from Qaidam Basin, China

Frontiers in Earth Science
Surface waves are widely used in the study of underground structures at various scales because of their dispersion characteristics in layered media. Whether in natural seismology or engineering seismology, surface wave analysis methods have matured and ...

NEAR SURFACE VELOCITY STRUCTURE OF ANDALUCIA (SOUTHERN SPAIN) AND ALBORAN SEA REGION FROM 0.15-2.0 HZ RAYLEIGH WAVES

Tecnociencia, 2004
  A methodology that has been applied for a relatively short time on Seismology is the modelling of very shallow structures from the inversion of dispersion values (group velocity of short period Rg waves).

Velocity Dispersion of the Open Cluster NGC 2571 by Radial Velocities and Proper Motions

The Astronomical Journal
We use a kernel density estimator method to evaluate the stellar velocity dispersion in the open cluster NGC 2571. We derive the 3D velocity dispersion using both proper motions as extracted from Gaia Data Release 3 and single-epoch radial velocities as ...

Apparent Effect of Dust Extinction on the Observed Outflow Velocity of Ionized Gas in Galaxy Mergers

The Astrophysical Journal
In this study, we examine photoionization outflows during the late stages of galaxy mergers, with a specific focus on the relation between the observed velocity of outflowing gas and the apparent effects of dust extinction.
