Iron and Silicate Dust Growth in the Galactic Interstellar Medium: Clues from Element Depletions [PDF]
, 2018 The interstellar abundances of refractory elements indicate a substantial depletion from the gas phase, which increases with gas density. Our recent model of dust evolution, based on hydrodynamic simulations of the life cycle of giant molecular clouds ...

The Near-infrared Extinction Law at High and Low Galactic Latitudes
The Astrophysical JournalThe Milky Way dust extinction curve in the near-infrared (NIR) follows a power-law form, but the value of the slope, β _NIR , is debated. Systematic variations in the slope of the Milky Way UV extinction curve are known to be correlated with variations ...

Magnetic Misalignment of Interstellar Dust Filaments
The Astrophysical Journal, 2023 We present evidence for scale-independent misalignment of interstellar dust filaments and magnetic fields. We estimate the misalignment by comparing millimeter-wave dust-polarization measurements from Planck with filamentary structures identified in ...

NEW ULTRAVIOLET EXTINCTION CURVES FOR INTERSTELLAR DUST IN M31 [PDF]
, 2015 New low-resolution UV spectra of a sample of reddened OB stars in M31 were obtained with the Hubble Space Telescope/STIS to study the wavelength dependence of interstellar extinction and the nature of the underlying dust grain populations.

Meteoritics &Planetary Science, Volume 60, Issue 8, Page 1851-1860, August 2025.Abstract Carbonaceous chondrites are meteorites originating from undifferentiated objects of the Solar System, which may retain signatures of primitive matter. Here, we present a comparative study between two CM chondrites Asuka 12236 and Paris, both considered among the most primitive in the carbonaceous chondrite meteorite collection.

The distribution of interstellar dust in CALIFA edge-on galaxies via oligochromatic radiative transfer fitting [PDF]
, 2014 We investigate the amount and spatial distribution of interstellar dust in edge-on spiral galaxies, using detailed radiative transfer modelling of a homogeneous sample of 12 galaxies selected from the Calar Alto Legacy Integral Field Area survey.

Angewandte Chemie, Volume 137, Issue 31, July 28, 2025.Ein neuer Bildungsweg für polyzyklische aromatische Stickstoffheterozyklen (PANH) wurde gefunden. Die Reaktion von Phenylnitren mit dem Propargylradikal führt zu Chinolin und belegt, dass Nitrene geeignete Vorläufer zum Einbau von Stickstoffheteroatomen sind.

SWIFT ULTRAVIOLET OBSERVATIONS OF SUPERNOVA 2014J IN M82: LARGE EXTINCTION FROM INTERSTELLAR DUST [PDF]
, 2014 We present optical and ultraviolet (UV) photometry and spectra of the very nearby and highly reddened supernova (SN) 2014J in M82 obtained with the Swift Ultra-Violet/Optical Telescope (UVOT).

Deep Space Network Radio Science and Ground‐Based Planetary Radar in the Next Decade
Radio Science, Volume 60, Issue 7, July 2025.Abstract The Deep Space Network (DSN) has been a core operational element of NASA's crewed and robotic exploration of the Solar System since the early 1960s. The primary role of the DSN has been to acquire telemetry and navigation data, but over the years, its radiometric and radar capabilities have expanded to form a system for obtaining unique ...
