Dust/ice mixing in cold regions and solid-state water in the diffuse interstellar medium
Henning, Thomas; Bouwman, Jeroen; Jäger, Cornelia +1 more
Whether ice in cold cosmic environments is physically separated from the silicate dust or mixed with individual silicate moieties is not known. However, different grain models give very different compositions and temperatures of grains. The aim of the present study is to compare the mid-infrared spectra of laboratory silicate grain/water ice mixtu…
Anomalous microwave emission from spinning nanodiamonds around stars
Frayer, D. T.; Smith, A. M. S.; Greaves, J. S. +3 more
Several interstellar environments produce anomalous microwave emission (AME), with brightness peaks at tens-of-gigahertz frequencies1. The emission's origins are uncertain; rapidly spinning nanoparticles could emit electric-dipole radiation2, but the polycyclic aromatic hydrocarbons that have been proposed as the carrier are …
