Molecular gas content of H i monsters and implications to cold gas content evolution in galaxies [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2014
We present 12CO (J=1-0) observations of a sample of local galaxies (0.043e10Msun from the ALFALFA survey and 8 LSBs with a comparable M(HI) (>1.5e10Msun). Our sample selection is purely based on the amount of neutral hydrogen, thereby providing a chance to study how atomic and molecular gas relate to each other in these HI-massive systems.

Cosmic Evolution of Gas Content and Accretion [PDF]

open access: yes, 2014
In the present universe, the gas is a minor component of giant galaxies, and its dominant phase is atomic (HI). During galaxy evolution in cosmic times, models predict that gas fractions were much higher in galaxies, and gas phases could be more balanced between molecular (H2) and atomic (HI). This gaseous evolution is certainly a key factor to explain

Combining K-Means Clustering and Random Forest to Evaluate the Gas Content of Coalbed Bed Methane Reservoirs

open access: yesGeofluids, 2021
The accurate calculation of the gas content of coalbed bed methane (CBM) reservoirs is of great significance. However, due to the weak correlation between the logging response of coalbed methane reservoirs and the gas content parameters and strong ...

Characteristics of Pore Structure and Gas Content of the Lower Paleozoic Shale from the Upper Yangtze Plate, South China

open access: yesEnergies, 2021
This study is predominantly about the differences in shale pore structure and the controlling factors of shale gas content between Lower Silurian and Lower Cambrian from the upper Yangtze plate, which are of great significance to the occurrence mechanism

The High Molecular Gas Content, and the Efficient Conversion of Neutral into Molecular Gas, in Jellyfish Galaxies [PDF]

open access: yesAstrophysical Journal, 2020
In the disks of four jellyfish galaxies from the GASP sample at redshift ∼0.05 we detect molecular gas masses systematically higher than in field galaxies.

Gas Content Regulates the Life Cycle of Star Formation and Black Hole Accretion in Galaxies [PDF]

open access: yesAstrophysical Journal, 2020
Feedback from active galactic nuclei (AGNs) is expected to impact the amount of cold gas in galaxies by driving strong galactic winds, by preventing external gas inflows, or by changing the thermodynamical state of the gas.

Gas Flows and Gas Contents in Globular Clusters [PDF]

open access: yesProgress of Theoretical Physics, 1979
The flow of gas injected from stars in globular clusters is numerically studied by means of the time-dependent beam scheme. By using structural parameters derived by Peterson and King (1975) and taking radiative cooling and ultraviolet heating into account, we obtain the time variation of velocity, temperature and density distributions in the gas flows

Molecular gas content of shell galaxies [PDF]

open access: yesAstronomy & Astrophysics, 2019
Shells are fine stellar structures that are identified by their arc-like shapes around a galaxy. They are currently thought to be vestiges of galaxy interactions and/or mergers. The study of their number, geometry, stellar populations, and gas content can help us to derive the interaction or merger history of a galaxy.

Automatic Measurement Device of Gas Desorption Data in Laboratory

open access: yesMeikuang Anquan, 2020
The method of direct volume measurement via drainage is often applied in the process of measuring gas desorption in laboratory, but there are many problems such as too many people involved, large error in reading and complicated measurement process. The

Experimental study and weighting analysis of factors influencing gas desorption

open access: yesFrontiers in Earth Science, 2023
Gas is one of the necessary contributing factors for coal and gas outburst accidents, and the gas desorbed in coal is the energy carrier in the outburst process.
