The Multi-phase HI of the Milky Way and Nearby Galaxies
Marc-Antoine Miville-Deschênes, J. R. Dawson, Narendra Nath Patra +30
Atomic hydrogen (HI) is the dominant baryonic component of the interstellar medium (ISM) in Milky Way-like galaxies and the reservoir from which molecular clouds and stars ultimate…
The Plane Quasar Survey: An Ionized Extension of the Magellanic Stream on the Northern Side of the Galactic Plane
Bo-Eun Choi, Jessica K. Werk, Kirill Tchernyshyov +5
The Magellanic Stream (MS) is a vast gaseous structure in the Milky Way halo, containing most of its mass in ionized form and tracing the interaction between the Large and Small Ma…
Kinetic tomography of the Galactic plane within 1.25 kiloparsecs from the Sun. The interstellar flows revealed by HI and CO line emission and 3D dust
J. D. Soler, S. Molinari, S. C. O. Glover +10
We present a reconstruction of the line-of-sight motions of the local interstellar medium (ISM) based on the combination of a model of the three-dimensional dust density distributi…
A Galactic Eclipse: The Small Magellanic Cloud is Forming Stars in Two, Superimposed Systems
Claire E. Murray, Sten Hasselquist, Joshua E. G. Peek +22
The structure and dynamics of the star-forming disk of the Small Magellanic Cloud (SMC) have long confounded us. The SMC is widely used as a prototype for galactic physics at low m…
Radial motions and radial gas flows in local spiral galaxies
Enrico M. Di Teodoro, Josh E. G. Peek
We determine radial velocities and mass flow rates in a sample of 54 local spiral galaxies by modelling high-resolution and high-sensitivity data of the atomic hydrogen emission li…
Small-Scale HI Channel Map Structure is Cold: Evidence from Na I Absorption at High Galactic Latitudes
J. E. G. Peek, S. E. Clark
The spatial distribution of neutral hydrogen (H I) emission is a powerful probe of interstellar medium physics. The small-scale structure in H I channel maps is often assumed to pr…
Do Androids Dream of Magnetic Fields? Using Neural Networks to Interpret the Turbulent Interstellar Medium
J. E. G. Peek, Blakesley Burkhart
The interstellar medium (ISM) of galaxies is composed of a turbulent magnetized plasma. In order to quantitatively measure relevant turbulent parameters of the ISM, a wide variety…
Catching the Birth of a Dark Molecular Cloud for the First Time
Pei Zuo, Di Li, J. E. G. Peek +5
The majority of hydrogen in the interstellar medium (ISM) is in atomic form. The transition from atoms to molecules and, in particular, the formation of the H molecule, is a ke…
Optically thick HI does not dominate dark gas in the local ISM
Claire E. Murray, J. E. G. Peek, Min-Young Lee +1
The local interstellar medium (ISM) is suffused with "dark" gas, identified by excess infrared and gamma ray emission, yet undetected by standard ISM tracers such as neutral hydrog…
HST/COS Observations of Ionized Gas Accretion at the Disk-halo Interface of M33
Y. Zheng, J. E. G. Peek, J. K. Werk +1
We report the detection of accreting ionized gas at the disk-halo interface of the nearby galaxy M33. We analyze HST/COS absorption-line spectra of seven ultraviolet-bright stars e…
Three-Dimensional Orientation of Compact High Velocity Clouds
F. Heitsch, B. Bartell, S. E. Clark +3
We present a proof-of-concept study of a method to estimate the inclination angle of compact high velocity clouds (CHVCs), i.e. the angle between a CHVC's trajectory and the line-o…
Neutral hydrogen structures trace dust polarization angle: Implications for cosmic microwave background foregrounds
S. E. Clark, J. Colin Hill, J. E. G. Peek +2
Using high-resolution data from the Galactic Arecibo L-Band Feed Array HI (GALFA-HI) survey, we show that linear structure in Galactic neutral hydrogen (HI) correlates with the mag…
Galactic and Magellanic Evolution with the SKA
Naomi M. McClure-Griffiths, Snezana Stanimirovic, Claire E. Murray +9
As we strive to understand how galaxies evolve it is crucial that we resolve physical processes and test emerging theories in nearby systems that we can observe in great detail. Ou…
Dust-to-Gas Ratios of the GALFA-HI Compact Cloud Catalog
Destry R. Saul, J. E. G. Peek, M. E. Putman
We have searched for infrared dust emission from subsets of compact, Galactic neutral hydrogen clouds, with the purpose of looking for dust in high-velocity clouds, identifying low…
Characterizing the Turbulent Properties of the Starless Molecular Cloud MBM16
Nickolas M. Pingel, Snezana Stanimirovic, J. E. G. Peek +13
We investigate turbulent properties of the non-star-forming, translucent molecular cloud, MBM16 by applying the statistical technique of a two-dimensional spatial power spectrum (S…
Ultraviolet Extinction at High Galactic Latitudes
J. E. G. Peek, David Schiminovich
In order to study the properties and effects of high Galactic latitude dust we present an analysis of 373,303 galaxies selected from the Galaxy Evolution Explorer (GALEX) All-Sky S…
The GALFA-HI Compact Cloud Catalog
Destry R. Saul, J. E. G. Peek, J. Grcevich +13
We present a catalog of 1964 isolated, compact neutral hydrogen clouds from the Galactic Arecibo L-Band Feed Array Survey Data Release One (GALFA-HI DR1). The clouds were identifie…
Gaseous Galaxy Halos
