... In one situation, we can use light from quasars to probe the material between us and them because that light may pass through one or more galaxies or gas clouds on its way to us. The gas inside the galaxies or the intergalactic clouds acts then as a filter, absorbing selected wavelengths from the quasar light. ... Light from a quasar must pass through clouds of gas and even faint galaxies -- each leaving its imprint on the light -- before we receive it here on Earth. ... Gravitational lensing . ...

NGC 5128! The supernova in the NGC 5128 galaxy was seen using a 1m telescope from the Sutherland Observatory in South Africa on 21st March 2016, but only using a H-Alpha filter. ... Supernova observed through H-Alpha Filter from Sutherland Observatory ! After receiving the images from the telescope via Las Cumbres Observatory, we then used Starlink Gaia to manipulate the images by changing contrast levels and the colour map in order to achieve the clearest possible results of the supernova. ...

Clusters of galaxies are the largest gravitationally bounded structures in the Universe dominated by dark matter. We review the observational appearance and physical models of plasma structures in clusters of galaxies. ... The knowledge of the complex dynamical and feedback processes is necessary to understand the energy and matter balance as well as to constrain the role of the non-thermal components of clusters. ...
