The eROSITA telescope array aboard the Spektrum Roentgen Gamma (SRG) satellite began surveying sky in December 2019, with aim of producing all-sky X-ray source lists and maps an unprecedented depth. Here we present catalogues both point-like extended sources using data acquired first six months survey operations (eRASS1; completed June 2020) over half whose proprietary rights lie German Consortium. We describe observation process, analysis pipelines, characteristics sources. With nearly 930...
Context. As the closest galaxy cluster, Virgo Cluster is an exemplary environment for study of large-scale filamentary structure and physical effects that are present in cluster outskirts but absent from more easily studied inner regions. Aims. Here, we analysis SRG/eROSITA data five all-sky surveys. Methods. eROSITA allows us to resolve entire its on scales between 1 kpc 3 Mpc, covering a total area sky about 25° by 25°. We utilized image manipulation techniques surface brightness profiles...
Context. The Virgo cluster is the nearest ( d = 16.5 Mpc) massive M ≥ 10 14 ⊙ ) galaxy and therefore a prime target for studying astrophysical processes in dense large-scale environments. In radio band, we can probe nonthermal components of interstellar medium, intracluster medium (ICM), active galactic nuclei (AGN). This allows an investigation impact environment on evolution galaxies contribution AGN to ICM heating. With ViCTORIA (VIrgo Cluster multi-Telescope Observations Radio...

The Virgo cluster is the nearest massive galaxy and thus a prime target to study astrophysical processes in dense large-scale environments. In radio band, we can probe non-thermal components of inter-stellar medium (ISM), intracluster (ICM) active galactic nuclei (AGN). With ViCTORIA (Virgo Cluster multi-Telescope Observations Radio Interacting galaxies AGN) project, are carrying out multiple wide-field surveys at different frequencies. We aim investigate impact environment on evolution...
