Multidimensional diffusive shock acceleration in the Winds from massive stars
… shock scenario may be extinguished due to free-free absorption. This would exclude the wind-embedded shock scenario from being able to explain the observed radio emission.

XUV probing of warm dense matter
Experiments were conducted to test models of free-free absorption in warm dense aluminium by Iglesias, Shaffer et al. and Hollebon et al., Radiative heating using L-shell x-rays from a high temperature palladium plasma was used to heat an aluminium foil to a temperature of 0.9±0.23eV. Before the …

Radio & Infrared Observations of the W3/W4/W5 Star-forming Regions
… with some localised regions demonstrating free-free self-absorption (§ 2), although we suspect a complete turnover of the H II regions outside of our observed range < 30 MHz. We obtain a spectral index of <i>ɑ</i> ~ -0.03±0.02 for 3C 58 and observe a possible plateau in the emission of HB3 …

The Bayesian Global Sky Model (B-GSM)
… The second component appears to correspond to free-free emission, and is primarily contained in the Galactic plane. This second component follows a power-law spectrum with a spectral index of β = -1.77±0.01 with curvature γ=-1.64±0.02 (reference frequency ν = 180 MHz). The pronounced curvature …
