The Small-scale Dynamo in a Multiphase Supernova-driven Medium
Magnetic fields grow quickly, even at early cosmological times, suggesting the action of a small-scale dynamo (SSD) in the interstellar medium (ISM) of galaxies. Many studies have focused on idealized, isotropic, homogeneous, turbulent driving of the SSD.

The recently published Interstellar Probe (ISP) study report describes a pragmatic mission concept with a launch window that starts in 2036 and is expected to reach several hundreds of astronomical units past the heliopause within a time frame of ≥50 ...

Multi-line Observations, Models, and Data Needed to Understand the Nature of UV-irradiated Interstellar Matter [PDF]
Far-ultraviolet photons from OB-type massive stars regulate the heating, ionization, and chemistry of much of the neutral interstellar gas in star-forming galaxies.

DYNAMIC SPECTRAL MAPPING OF INTERSTELLAR PLASMA LENSES [PDF]
ABSTRACT Compact radio sources sometimes exhibit intervals of large, rapid changes in their flux density, due to lensing by interstellar plasma crossing the line of sight. A novel survey program has made it possible to discover these “Extreme Scattering Events” (ESEs) in real time, resulting in a high-quality dynamic spectrum of an ESE ...

The Influence of Outflow Feedback in Clumps
We analyzed the influence of outflow feedback from two perspectives: turbulent support and potential disruptive effect, of which 694 clumps and 188 have been identified as outflow candidates.

Aspects of the Mass Distribution of Interstellar Dust Grains in the Solar System from In-Situ Measurements [PDF]
The in-situ detection of interstellar dust grains in the Solar System by the dust instruments on-board the Ulysses and Galileo spacecraft as well as the recent measurements of hyperbolic radar meteors give information on the properties of the ...

High-mass Starless Clumps: Dynamical State and Correlation between Physical Parameters
In order to study the initial conditions of massive star formation, we have previously built a sample of 463 high-mass starless clumps (HMSCs) across the inner Galactic plane covered by multiple continuum surveys.
