Infrared optical signature reveals the source–dependency and along–transport evolution of dust mineralogy as shown by laboratory study

open access: yesScientific Reports, 2023
Advancing knowledge of the mineralogical composition of dust is key for understanding and predicting its climate and environmental impacts. The variability of dust mineralogy from one source to another and its evolution during atmospheric transport is ...

SpeX Near-infrared Spectroscopic Extinction Curves in the Milky Way

open access: yesThe Astrophysical Journal, 2022
Interstellar dust extinction curves provide valuable information about dust properties, including the composition and size of the dust grains, and are essential to correct observations for the effects of interstellar dust.

A 3-D evaluation of the MACC reanalysis dust product over Europe, northern Africa and Middle East using CALIOP/CALIPSO dust satellite observations [PDF]

open access: yesAtmospheric Chemistry and Physics, 2018
The MACC reanalysis dust product is evaluated over Europe, northern Africa and the Middle East using the EARLINET-optimized CALIOP/CALIPSO pure dust satellite-based product LIVAS (2007–2012).

Galactic dust and extinction [PDF]

open access: yesSymposium - International Astronomical Union, 1979
The ratio R between visual extinction and colour excess, is slightly larger than 3 and does not vary much throughout our part of the Galaxy. The distribution of dust in the galactic plane shows, on the large scale, a gradient with higher colour excesses towards 1=50° than towards 1=230°. On the smaller scale, much of the dust responsible for extinction

Comparison of distance measurements to dust clouds using GRB X-ray halos and 3D dust extinction [PDF]

open access: yes, 2023
X-ray photons from energetic sources such as gamma-ray bursts (GRBs) can be scattered on dust clouds in the Milky Way, creating a time-evolving halo around the GRB position.

Dust extinction in the first galaxies [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2018
Using cosmological volume simulations and a custom built sub-grid model for Pop~III star formation, we examine the baseline dust extinction in the first galaxies due to Pop~III metal enrichment in the first billion years of cosmic history. We find that while the most enriched, high-density lines of sight in primordial galaxies can experience a ...

The influence of dust optical properties on the colour of simulated MSG-SEVIRI Desert Dust infrared imagery [PDF]

open access: yesAtmospheric Chemistry and Physics, 2018
Satellite imagery of atmospheric mineral dust is sensitive to the optical properties of the dust, governed by the mineral refractive indices, particle size, and particle shape.

»Hope dies – Action begins« [PDF]

open access: yes, 2019
"Hope dies - action begins" - this is the motto of the new global environmental movement "Extinction Rebellion" (XR). XR wants to make us all aware of finally taking radical measures against the gigantic species extinction and climate catastrophe.
