The Solar Sodium D-Lines--I: Profiles Computed Assuming Pure Absorption

On the effects of assuming flow profiles in nonequilibrium simulations

measurement the absorption capacity of solar energy storage technology

Although solar energy is one of the most important renewable energies in Iran that most areas of the country, especially the Central Desert, have considerable ability to use, but the random nature of this type of energy makes it difficult to predict its output power and may cause problems in the performance of the feed systems. For this reason, the use of energy storage systems for periods of l...

An ALMA Early Science survey of molecular absorption lines toward PKS 1830-211 Analysis of the absorption profiles

We present the first results of an ALMA spectral survey of strong absorption lines for common interstellar species in the z = 0.89 molecular absorber toward the lensed blazar PKS 1830−211. The dataset brings essential information on the structure and composition of the absorbing gas in the foreground galaxy. In particular, we find absorption over large velocity intervals ( 100 km s−1) toward bo...

The 9.7 and 18 μm silicate absorption profiles towards diffuse and molecular cloud lines-of-sight

Context. Studying the composition of dust in the interstellar medium (ISM) is crucial for understanding the cycle of dust in our galaxy. Aims. The mid-infrared spectral signature of amorphous silicates, the most abundant dust species in the ISM, is studied in different lines-of-sight through the Galactic plane, thus probing different conditions in the ISM. Methods. We have analysed ten spectra ...
