Study of H i Turbulence in the SMC Using Multipoint Structure Functions
The Astrophysical JournalTurbulence in the interstellar medium (ISM) plays an important role in many physical processes, including forming stars and shaping complex ISM structures.

H i Content of Group Galaxies from the FAST All Sky H i Survey
The Astrophysical JournalWe investigate the atomic gas (H i ) content of galaxies in groups using early data from the Five-hundred-meter Aperture Spherical Radio Telescope (FAST) All Sky H i survey. Taking advantage of FAST’s blind, wide-area coverage and uniform sensitivity, we

The Impact of External Gas Accretion on the Distribution of H I Gas in Galaxies
The Astrophysical JournalUsing the data from Mapping Nearby Galaxies at Apache Point Observatory (MaNGA) and H i -MaNGA surveys, we build a sample of 37 gas–star misaligned galaxies with robust H i detections, which are believed to have undergone external gas accretion processes.

Pervasive Cavity-rim Structure for Star Formation in Dwarf Irregular Galaxies
The Astrophysical JournalUnsharp-mask images of H I emission from 36 dwarf irregular (dIrr) galaxies illustrate star formation in dispersed clouds and on the rims of large cavities. The cavities can extend for a radial scale length and typically have circular or slightly sheared

n-Alkanes formed by methyl-methylene addition as a source of meteoritic aliphatics
Communications ChemistryAliphatics prevail in asteroids, comets, meteorites and other bodies in our solar system. They are also found in the interstellar and circumstellar media both in gas-phase and in dust grains.

The interstellar molecular hydrogen observed in the ultraviolet spectrum of delta Scorpii [PDF]
, 1972 Molecular hydrogen bands of the Lyman and Werner systems were observed in the ultraviolet, interstellar spectrum of delta Sco. The average molecular column density is given, and the average temperature of the gas of which the molecules are part is 47 K ...

The ratio of molecular to atomic gas in spiral galaxies as a function of morphological type [PDF]
, 1990 In order to gain an understanding of the global processes which influence cloud and star formation in disk galaxies, it is necessary to determine the relative amounts of atomic, molecular, and ionized gas both as a function of position in galaxies and ...
