Marchal et al. (2019) – ROHSA: Regularized Optimization for Hyper-Spectral Analysis – Application to phase separation of 21 cm data

Extracting the multiphase structure of the neutral interstellar medium (ISM) is key to understand the star formation in galaxies. The radiative condensation of the diffuse warm neutral medium producing a

Clark, Peek & Miville-Deschênes (2019) – The Physical Nature of Neutral Hydrogen Intensity Structure

We investigate the physical properties of structures seen in channel map observations of 21 cm neutral hydrogen (H I) emission. H I intensity maps display prominent linear structures that are

Heiles et al. (2019) – The interstellar medium: the key component in galactic evolution and modern cosmology

The gases of the interstellar medium (ISM) possess orders of magnitude more mass than those of all the stars combined and are thus the prime component of the baryonic Universe.

Koley & Roy (2018) – Estimating kinetic temperature from H I 21 cm absorption studies: correction for the turbulence broadening

Neutral hydrogen 21 cm transition is a useful tracer of the neutral interstellar medium. However, inferring physical condition from the observed 21 cm absorption and/or emission spectra is often not

Chiang & Ménard (2018) – Extragalactic Imprints in Galactic Dust Maps

Extragalactic astronomy relies on the accurate estimation of source photometry corrected for Milky Way dust extinction. This has motivated the creation of a number of “Galactic” dust maps. We investigate

Lockman et al. (2008) – The Smith Cloud: A High-Velocity Cloud Colliding with the Milky Way

New 21 cm H I observations made with the Green Bank Telescope show that the high-velocity cloud known as the Smith Cloud has a striking cometary appearance and many indications

Liszt (2014) – N(H I)/E(B – V)

We explore the relationship between dust-emission derived reddening E(B – V) and atomic hydrogen column density N(H I) derived from 21 cm emission surveys. We consider measurements at galactic latitudes

We study infrared emission of 17 isolated, diffuse clouds with masses of order {10}2 {M}&sun; to test the hypothesis that grain property variations cause the apparently low gas-to-dust ratios that

Skalidis et al. (2018) – Local measurements of the mean interstellar polarization at high Galactic latitudes

Very little information exists concerning the properties of the interstellar medium (ISM)-induced starlight polarization at high Galactic latitudes. Future optopolarimetric surveys promise to fill this gap. We conduct a small-scale
