Over the next seven years, the government will fund ten centres of excellence addressing scientific issues of importance to Estonia. The University of Tartu has tight connections with all of them.
Multiple-cluster systems, i.e. superclusters, contain large numbers of galaxies assembled in clusters inter-connected by multi-scale filamentary networks.
Coronal Mass Ejections (CMEs) are massive blobs of plasma and magnetic fields that erupt from the Sun and can travel towards the Earth and drive near-Earth space weather.
We use our statistically complete and well defined CLASSIX Cluster Survey based on the ROSAT X-ray sky to map the density distribution in the local Universe.
Photometric observations of the star HD 191765 have been made before. However, observing this star with a modern CCD photometer is essential and relevant.
The possibility of the recently detected signal being originated from supermassive black hole binaries is discussed as well as a potential cosmological origin.
