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,

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

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.

Effects of Velocity and Permeability on Tracer Dispersion in Porous Media
Applied Sciences, 2021 During micro-scale tracer flow in porous media, the permeability and fluid velocity significantly affect the fluid dispersion properties of the media. However, the relationships between the dispersion coefficient, permeability, and fluid velocity in core

The Case for the Fundamental MBH-σ Relation
Frontiers in Physics, 2020 Strong scaling relations between host galaxy properties (such as stellar mass, bulge mass, luminosity, effective radius etc) and their nuclear supermassive black hole's mass point toward a close co-evolution.

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 ...

Stellar Velocity Dispersion: Linking Quiescent Galaxies to Their Dark Matter Halos [PDF]
Astrophysical Journal, 2018 We analyze the Illustris-1 hydrodynamical cosmological simulation to explore the stellar velocity dispersion of quiescent galaxies as an observational probe of dark matter halo velocity dispersion and mass.

Calculation of velocity dispersion of the nearby galaxies using different stellar template libraries [PDF]
Serbian Astronomical Journal, 2010 We present the central velocity dispersion measurements of the nearby galaxies from the Sloan Digital Sky Survey (SDSS). Using the sample from the paper by Ho et al. 2009, we have selected 23 galaxies for which we calculate the velocity dispersion.
