FEASTS Compared with Simulations: Abnormally Irregular and Extended H i Morphologies at a Column Density of 1018 cm−2 in TNG50 and Auriga

The Astrophysical Journal
With new atomic-hydrogen (H i ) observations of FAST Extended Atlas of Selected Targets Survey (FEASTS), we present the first statistical comparison of H i morphology between observations and cosmological simulations, focusing on low-column-density (∼10 ^

The Impact of External Gas Accretion on the Distribution of H I Gas in Galaxies

The Astrophysical Journal
Using 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.

Development of a reusuable atomic oxygen sensor using oxide thick films

, 2009
The aim of this project was to develop a thick film sensor made of zinc oxide that would accurately respond to various fluxes of atomic oxygen (AO), allowing it to be regenerated after saturation.

Pervasive Cavity-rim Structure for Star Formation in Dwarf Irregular Galaxies

The Astrophysical Journal
Unsharp-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 Chemistry
Aliphatics 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.

Interstellar gas within  ~10 pc of Sagittarius A

, 2012
Aims. We seek to obtain a coherent and realistic three-dimensional picture of the interstellar gas out to about 10 pc of the dynamical center of our Galaxy, which is supposed to be at Sgr A∗. Methods.
