## Li & Klein (2019) – Magnetized interstellar molecular clouds: II. The Large-Scale Structure and Dynamics of Filamentary Molecular Clouds

Ideal MHD high resolution AMR simulations with driven turbulence and self-gravity have been performed that demonstrate the formation of long filamentary molecular clouds at the converging location of large-scale turbulence

## Alig et al. (2018) – Simulating the Impact of the Smith Cloud

We investigate the future evolution of the Smith Cloud by performing hydrodynamical simulations of the cloud impact onto the gaseous Milky Way Galactic disk. We assume a local origin for

## Müller et al. (2018) – Sharpening up Galactic all-sky maps with complementary data – A machine learning approach

Galactic all-sky maps at very disparate frequencies, like in the radio and $\gamma$-ray regime, show similar morphological structures. This mutual information reflects the imprint of the various physical components of

## Grossschedl et al. (2018) – 3D shape of Orion A from Gaia DR2

We use the $\mathit{Gaia}$ DR2 distances of about 700 mid-infrared selected young stellar objects in the benchmark giant molecular cloud Orion A to infer its 3D shape and orientation. We

## Murray et al. (2015) – The 21-SPONGE HI Absorption Survey I: Techniques and Initial Results

We present methods and results from “21 cm Spectral Line Observations of Neutral Gas with the EVLA” (21-SPONGE), a large survey for Galactic neutral hydrogen (H i) absorption with the

## Heiles (1997) – Tiny-Scale Atomic Structure and the Cold Neutral Medium

We consider the tiny-scale atomic structure (TSAS) on scales of tens of astronomical units, which has been detected by 21 cm absorption lines against quasars with VLBI techniques, against pulsars

## Stanimirovic et al. (2010) – Arecibo Multi-epoch H I Absorption Measurements Against Pulsars: Tiny-scale Atomic Structure

We present results from multi-epoch neutral hydrogen (H I) absorption observations of six bright pulsars with the Arecibo telescope. Moving through the interstellar medium (ISM) with transverse velocities of 10-150

## Stanimirovic & Heiles (2005) – The Thinnest Cold H I Clouds in the Diffuse Interstellar Medium?

We confirm and discuss recently discovered cold H I clouds with column densities among the lowest ever detected. The column densities of the cold neutral medium (CNM) toward 3C 286

## Heiles & Troland (2003) – The Millennium Arecibo 21 Centimeter Absorption-Line Survey. II. Properties of the Warm and Cold Neutral Media

We use the Gaussian fit results of Paper I to investigate the properties of interstellar H I in the solar neighborhood. The warm and cold neutral media (WNM and CNM)
