Experimental verification of agglomeration effects in infrared spectra on micron-sized particles

by A. Tamanai, J. Vogt, C. Huck, U. Mick, et al. A&A 619, A110

This paper describes an application of nanoparticle laboratory methods to simulate astronomical silicate dust aggregate emission features. It is worth highlighting, as to our knowledge it is a first and an example of what can be done now with microtechniques in the lab that extend beyond the coarser agglomerations previously used. Control of the particle structures is expected in the near future, especially distinguishing embedded and surface scatterers. The results are compared with several different methods for computing grain properties.
