Kreckel et al. (2018) – A 50 pc Scale View of Star Formation Efficiency across NGC 628

Star formation is a multi-scale process that requires tracing cloud formation and stellar feedback within the local (≲kpc) and global galaxy environment. We present first results from two large observing

Nguyen et al. (2018) – Dust-Gas Scaling Relations and OH Abundance in the Galactic ISM

Observations of interstellar dust are often used as a proxy for total gas column density N H. By comparing Planck thermal dust data (Release 1.2) and new dust reddening maps

Planck Collaboration et al. (2018) – Planck 2018 results. XII. Galactic astrophysics using polarized dust emission

We present 353 GHz full-sky maps of the polarization fraction $p$, angle $\psi$, and dispersion of angles $S$ of Galactic dust thermal emission produced from the 2018 release of Planck

Garratt-Smithson et al. (2018) – Does slow and steady win the race? Investigating feedback processes in giant molecular clouds

We investigate the effects of gradual heating on the evolution of turbulent molecular clouds of mass 2 × 106 M⊙ and virial parameters ranging between 0.7 – 1.2. This gradual

Hopkins & Squire (2018) – Ubiquitous Instabilities of Dust Moving in Magnetized Gas

Squire & Hopkins (2017) showed that coupled dust-gas mixtures are generically subject to “resonant drag instabilities” (RDIs), which drive violently-growing fluctuations in both. But the role of magnetic fields and

Pattle et al. (2018) – First Observations of the Magnetic Field inside the Pillars of Creation: Results from the BISTRO Survey

We present the first high-resolution, submillimeter-wavelength polarimetric observations of—and thus direct observations of the magnetic field morphology within—the dense gas of the Pillars of Creation in M16. These 850 μm

Sun et al. (2018) – Cloud-scale Molecular Gas Properties in 15 Nearby Galaxies

We measure the velocity dispersion, σ, and surface density, Σ, of the molecular gas in nearby galaxies from CO spectral line cubes with spatial resolution 45–120 pc, matched to the

Forgan, Ramón-Fox & Bonnell (2018) – Classifying and modelling spiral structures in hydrodynamic simulations of astrophysical discs

We demonstrate numerical techniques for automatic identification of individual spiral arms in hydrodynamic simulations of astrophysical discs. Building on our earlier work, which used tensor classification to identify regions that

Wu et al. (2018) – Giant molecular cloud collisions as triggers of star formation. VI. Collision-induced turbulence

We investigate collisions between giant molecular clouds (GMCs) as potential generators of their internal turbulence. Using magnetohydrodynamic (MHD) simulations of self-gravitating, magnetized, turbulent GMCs, we compare kinematic and dynamic properties

Clark (2018) – A New Probe of Line-of-sight Magnetic Field Tangling

The Galactic neutral hydrogen (H I ) sky at high Galactic latitudes is suffused with linear structure. Particularly prominent in narrow spectral intervals, these linear H I features are well

Fissel et al. (2018) – Relative Alignment Between the Magnetic Field and Molecular Gas Structure in the Vela C Giant Molecular Cloud using Low and High Density Tracers

We compare the magnetic field orientation for the young giant molecular cloud Vela C inferred from 500-$\mu$m polarization maps made with the BLASTPol balloon-borne polarimeter to the orientation of structures

Li et al. (2018) – Where is OH and Does It Trace the Dark Molecular Gas (DMG)?

Hydroxyl (OH) is expected to be abundant in diffuse interstellar molecular gas because it forms along with H2 under similar conditions and forms within a similar extinction range. We have

Martini et al. (2018) – H I Kinematics along the Minor Axis of M82

M82 is one of the best-studied starburst galaxies in the local universe, and is consequently a benchmark for studying star formation feedback at both low and high redshift. We present

Ramón-Fox & Bonnell (2018) – Streaming motions and kinematic distances to molecular clouds

We present high-resolution smoothed particle hydrodynamics simulations of a region of gas flowing in a spiral arm and identify dense gas clouds to investigate their kinematics with respect to a

Gomez, Vazquez-Semadeni & Zamora-Aviles (2018) – The magnetic field structure in molecular cloud filaments

We explore the structure of magnetic field lines in and around filaments in simulations of molecular clouds undergoing global, multi-scale gravitational collapse. In these simulations, filaments are not in a

Körtgen, Federrath & Banerjee (2017) – The driving of turbulence in simulations of molecular cloud formation and evolution

Molecular clouds are to a great extent influenced by turbulent motions in the gas. Numerical and observational studies indicate that the star formation rate and efficiency crucially depend on the

Koo et al. (2017) – Tracing the Spiral Structure of the Outer Milky Way with Dense Atomic Hydrogen Gas

We present a new face-on map of dense neutral atomic hydrogen ({{H}} i) gas in the outer Galaxy. Our map has been produced from the Leiden/Argentine/Bonn {{H}} i 21 cm

Wareing et al. (2016) – Magnetohydrodynamical simulation of the formation of clumps and filaments in quiescent diffuse medium by thermal instability

We have used the adaptive mesh refinement hydrodynamic code, MG, to perform idealized 3D magnetohydrodynamical simulations of the formation of clumpy and filamentary structure in a thermally unstable medium without

Safron et al. (2015) – Hops 383: an Outbursting Class 0 Protostar in Orion

We report the dramatic mid-infrared brightening between 2004 and 2006 of Herschel Orion Protostar Survey (HOPS) 383, a deeply embedded protostar adjacent to NGC 1977 in Orion. By 2008, the

Magnetohydrodynamic turbulence is able to create hierarchical structures in the interstellar medium (ISM) that are correlated on a wide range of scales via the energy cascade. We use hierarchical tree

Chen et al. (1997) – Refined Similarity Hypothesis for Transverse Structure Functions in Fluid Turbulence

We argue on the basis of empirical data that Kolmogorov’s refined similarity hypothesis (RSH) needs to be modified for transverse velocity increments, and propose an alternative. In this new form,
