Blazars are active galaxies centered around supermassive black holes. They generate strong electromagnetic radiation in a very wide spectrum – from visible light to radio, infrared, ultraviolet, X-ray, and gamma radiation. All those kinds of radiation are studied by Dr. Alicja Wierzcholska (PAS Institute of Nuclear Physics), winner of START competition organized by the Foundation for Polish Science.
Without detailed knowledge of the properties of the materials we use today's technology could neither function nor develop. A new description of electron scattering in the surface layers of samples proposed by the Institute of Physical Chemistry of the Polish Academy of Sciences in Warsaw significantly speeds up materials analysis and enables a better understanding of what can really be seen in a sample.
