Interstellar gas, dust and diffuse bands in the SMC

, 2007
Aims. In order to gain new insight into the unidentified identity of the diffuse interstellar band (DIB) carriers, this paper describes research into possible links between the shape of the interstellar extinction curve ( including the 2175 angstrom bump

Observed Timescales of Stellar Feedback in Star-forming, Low-mass Galaxies

The Astronomical Journal
Understanding the timescales of atomic gas turbulence is crucial to understanding the interplay between star formation and the interstellar medium (ISM). To investigate the timescales of turbulence low-mass galaxies (10 ^6.8

The hot and dusty interstellar medium through X-ray spectroscopy [PDF]

, 2020
The interstellar medium fills the space between the stars in our Galaxy. Depending on the thermodynamic state, it is possible to distinguish between three phases: a cold and dense phase consisting of clouds of atomic and molecular hydrogen; a warm inter ...

The H i Reservoir in Central Spiral Galaxies and the Implied Star Formation Process

The Astrophysical Journal Letters
The cold interstellar medium (ISM) as the raw material for star formation is critical to understanding galaxy evolution. It is generally understood that galaxies stop making stars when, in one way or another, they run out of gas. However, here we provide

A dirty window: diffuse and translucent molecular gas in the interstellar medium

, 2017
This book provides an introduction to the physics of interstellar gas in the Galaxy. It deals with the diffuse interstellar medium which supplies a complex environment for exploring the neutral gas content of a galaxy like the Milky Way and the ...

Cool Dark Gas in Cygnus X: The First Large-scale Mapping of Low-frequency Carbon Recombination Lines

The Astrophysical Journal
Understanding the transition from atomic gas to molecular gas is critical to explain the formation and evolution of molecular clouds. However, the gas phases involved, cold H i and CO-dark molecular gas, are challenging to directly observe and physically

FAST Search for Circumstellar Atomic Hydrogen. IV. Bubbles Associated with Planetary Nebulae

The Astronomical Journal
Investigating the bubbles generated by the interaction between asymptotic giant branch stellar outflows and the interstellar medium (ISM) is pivotal for elucidating the mechanism by which evolved low- to intermediate-mass stars enrich the ISM with heavy ...

A gas-phase “top-down” chemical link between aldehydes and alcohols

Frontiers in Astronomy and Space Sciences
IntroductionAlcohols and aldehydes represent two key classes of interstellar complex organic molecules (COMs). This work seeks to better understand their possible chemical connections, with a focus on such molecules in the sources of the star-forming ...
