What drives the velocity dispersion of ionized gas in star-forming galaxies? [PDF]
Monthly notices of the Royal Astronomical Society, 2019 We analyse the intrinsic velocity dispersion properties of 648 star-forming galaxies observed by the Mapping Nearby Galaxies at Apache Point Observatory (MaNGA) survey, to explore the relation of intrinsic gas velocity dispersions with star formation ...

The Velocity Dispersion Function for Quiescent Galaxies in the Local Universe [PDF]
, 2017 We investigate the distribution of central velocity dispersions for quiescent galaxies in the SDSS at 0.03 ≤ z ≤ 0.10. To construct the field velocity dispersion function (VDF), we construct a velocity dispersion complete sample of quiescent galaxies ...

Velocity Dispersions of Quiescent Galaxies in IllustrisTNG
The Astrophysical JournalWe examine the central stellar velocity dispersion of subhalos based on IllustrisTNG cosmological hydrodynamic simulations. The central velocity dispersion is a fundamental observable that links galaxies with their dark matter subhalos.

Sensors, 2021 Horizontal-to-Vertical Spectral Ratios (HVSR) and Rayleigh group velocity dispersion curves (DC) can be used to estimate the shallow S-wave velocity (VS) structure. Knowing the VS structure is important for geophysical data interpretation either in order

Velocity Dispersion of the GD-1 Stellar Stream [PDF]
Astrophysical Journal Letters, 2020 Tidally dissolved globular clusters form thin stellar streams that preserve a historical record of their past evolution. We report a radial velocity dispersion of 2.1 ± 0.3 km s−1 in the GD-1 stellar stream using a sample of 43 spectroscopically ...

Wave Properties of Gas-Hydrate Bearing Sediments Based on Poroelasticity
Frontiers in Earth Science, 2021 Natural gas hydrates have the properties of ice with a microporous structure and its concentration in sediments highly affects the wave velocity and attenuation. Previous studies have performed investigations based on the measurements of laboratory data,

Velocity dispersion in the interstellar medium of early galaxies [PDF]
Monthly notices of the Royal Astronomical Society, 2020 We study the structure of spatially resolved, line-of-sight velocity dispersion for galaxies in the Epoch of Reionization (EoR) traced by [C $\scriptstyle \rm II$] $158\, \mu \rm {m}$ line emission.

Dynamic fluid transport property of hydraulic fractures and its evaluation using acoustic logging
Petroleum Exploration and Development, 2022 The existing acoustic logging methods for evaluating the hydraulic fracturing effectiveness usually use the fracture density to evaluate the fracture volume, and the results often cannot accurately reflect the actual productivity.
