Geostandards and Geoanalytical Research, Volume 49, Issue 3, Page 495-533, September 2025.Key Points Synchrotron nano‐imaging is necessary to locate elemental nanophases. Trace metal quantification requires high sensitivity nano‐XRF. Trace metal speciation relies on nano‐XANES using nano‐XRF. This chapter (Nano‐Imaging for Advanced X‐ray Fluorescence and Absorption Spectroscopy Applications) is a contribution to the Geostandards and ...

Dust-polarization Maps and Interstellar Turbulence [PDF]
, 2016 Perhaps the most intriguing result of Planck’s dust-polarization measurements is the observation that the power in the E-mode polarization is twice that in the B mode, as opposed to pre-Planck expectations of roughly equal dust powers in the E and B ...

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.

On the Absorption and Emission Properties of Interstellar Grains
, 2005 Our current understanding of the absorption and emission properties of interstellar grains are reviewed. The constraints placed by the Kramers-Kronig relation on the wavelength-dependence and the maximum allowable quantity of the dust absorption are ...

Properties of interstellar dust [PDF]
Journal of Geophysical Research: Space Physics, 2000 The reference abundance of the interstellar medium (the abundance of elements in gas + dust), until recently assumed to be solar, is discussed because of its great importance for the composition of dust. For some important elements (O, N, and probably more), three lines of reasoning (observed gas‐phase abundances, H II regions, and stellar abundances ...

Observation of Diffuse Galactic Light Near the Galactic Center with ONC-T on Board Hayabusa2
The Astrophysical JournalDiffuse Galactic light (DGL) is starlight scattered by interstellar dust. In visible wavelengths, earlier studies observed DGL toward regions of low optical depth in high Galactic latitude, and show marginal consistency with a theoretical model assuming ...

Properties of Interstellar Dust [PDF]
International Astronomical Union Colloquium, 1996 AbstractIn this review, the picture of the interstellar dust is outlined from the viewpoint of its role in galactic evolution. The modern concept of distinct dust populations is presented. The properties of the dust grains in the diffuse interstellar medium and in the molecular clouds are described.

Orbital evolution under the action of fast interstellar gas flow with non-constant drag coefficient
, 2012 The acceleration of a spherical dust particle caused by an interstellar gas flow depends on the drag coefficient which is, for the given particle and flow of interstellar gas, a specific function of the relative speed of the dust particle with respect to
