The Interstellar Environment of our Galaxy [PDF]

open access: yes, 2001
We review the current knowledge and understanding of the interstellar medium of our galaxy. We first present each of the three basic constituents - ordinary matter, cosmic rays, and magnetic fields - of the interstellar medium, laying emphasis on their ...

Infrared Emission from Interstellar Dust. II. The Diffuse Interstellar Medium [PDF]

open access: yes, 2001
We present a quantitative model for the infrared emission from dust in the diffuse interstellar medium. The model consists of a mixture of amorphous silicate grains and carbonaceous grains, each with a wide size distribution ranging from molecules ...

Mapping local interstellar medium with diffuse interstellar bands [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2020
ABSTRACT With the use of the data from archives, we studied the correlations between the equivalent widths of four diffuse interstellar bands (4430, 5780, 5797, 6284 $\mathring{\rm A}$) and properties of the target stars (colour excess values, distances, and Galactic coordinates).

Mapping The Interstellar Medium With Near-Infrared Diffuse Interstellar Bands [PDF]

open access: yes, 2015
We map the distribution and properties of the Milky Way's interstellar medium as traced by diffuse interstellar bands (DIBs) detected in near-infrared stellar spectra from the SDSS-III/APOGEE survey.

Presumed Detection of C5 Molecule in the Interstellar Medium

open access: yesThe Astrophysical Journal, 2022
The paper suggests the presence of the carbon chain C _5 molecule in translucent, interstellar H i clouds. This species, the only five atom interstellar molecule, observable in dark, translucent clouds, seems to be observable in reasonably dense clouds ...

A Plasma Instability Theory of Gamma-Ray Burst Emission [PDF]

open access: yes, 1999
A new theory for gamma-ray burst radiation is presented. In this theory, magnetic fields and relativistic electrons are created through plasma processes arising as a relativistic shell passes through the interstellar medium.

Dust evolution, a global view I. Nanoparticles, nascence, nitrogen and natural selection … joining the dots [PDF]

open access: yesRoyal Society Open Science, 2016
The role and importance of nanoparticles for interstellar chemistry and beyond is explored within the framework of The Heterogeneous dust Evolution Model for Interstellar Solids (THEMIS), focusing on their active surface chemistry, the effects of ...

Dust evolution, a global view: III. Core/mantle grains, organic nano-globules, comets and surface chemistry [PDF]

open access: yesRoyal Society Open Science, 2016
Within the framework of The Heterogeneous dust Evolution Model for Interstellar Solids (THEMIS), this work explores the surface processes and chemistry relating to core/mantle interstellar and cometary grain structures and their influence on the nature ...

Supernovae Origin for the Low-latitude Intermediate-velocity Arch and the North Celestial Pole Loop

open access: yesThe Astrophysical Journal, 2023
Supernova explosions attributed to the unseen companion in several binary systems identified by the Third Gaia Data Release (Gaia DR3) may be responsible for a number of well-known and well-studied features in the radio sky, including the low-latitude ...

A future interstellar probe on the dynamic heliosphere and its interaction with the very local interstellar medium: In-situ particle and fields measurements and remotely sensed ENAs

open access: yesFrontiers in Astronomy and Space Sciences, 2023
The recently published Interstellar Probe (ISP) study report describes a pragmatic mission concept with a launch window that starts in 2036 and is expected to reach several hundreds of astronomical units past the heliopause within a time frame of ≥50 ...
