High-resolution X-ray spectroscopy of the Interstellar Medium [PDF]
, 2010 We present recent results on high‐resolution X‐ray absorption measurements of the interstellar medium. We show the results from our recent analysis of the absorption towards the Crab nebula, and discuss improvements in the absorption edge structure that ...

Disclosing Identities in Diffuse Interstellar Bands
, 2011 The linear isomer of C 3 H 2 has been proposed as the source of broad absorption bands in diffuse interstellar clouds, but it is still being debated.

H i Kinematics and the E(B − V)/N(H i) Ratio
The Astrophysical JournalThe λ 21 cm H i emission that is used to trace the gas-to-dust ratio at high Galactic latitudes has contributions from material beyond the Milky Way disk, with uncertain and likely subsolar metallicity and dust content.

The organic component of interstellar grains [PDF]
, 1986 The 3.4 micron absorption feature observed in the spectrum of a number of Galactic Center (GC) sources indicates the presence of organic molecules in the interstellar medium.

Nature Communications, 2019 Carbon monoxide is the main C and O reservoir in interstellar media, where it undergoes photochemistry. The authors show that isotopic substitution affects not only its absorption. spectrum and photodissociation rates but also the branching ratio, key to

Photodissociation of OH in interstellar clouds
, 1984 Calculations are presented of the lifetime of OH against photodissociation by the interstellar radiation field as a function of depth into interstellar clouds containing grains of various scattering properties.

The Astrophysical JournalThe abundance of elements in the interstellar medium is a key facet for many fields of astrophysical study. In the soft X-ray spectra, absorption by interstellar gas can result in deep absorption features that affect continuum measurements. In this paper,

Oxygen, neon, and iron X-ray absorption in the local interstellar medium
, 2016 Aims. We present a detailed study of X-ray absorption in the local interstellar medium by analyzing the X-ray spectra of 24 galactic sources obtained with the Chandra High Energy Transmission Grating Spectrometer and the XMM-Newton Reflection Grating ...
