The eROSITA telescope array aboard the Spektrum Roentgen Gamma (SRG) satellite
began surveying the sky in December 2019, with the aim of producing all-sky X-ray source …

Clusters of galaxies can be used as powerful probes to study astrophysical processes on
large scales, test theories of the growth of structure, and constrain cosmological models. The …

The evolution of the cluster mass function traces the growth of linear density perturbations,
providing valuable insights into the growth of structures, the nature of dark matter, and the …

X-ray quasi-periodic eruptions (QPEs) are a novel addition to the group of extragalactic
transients. With only a select number of known sources, and many more models published …

The current standard model of cosmology successfully describes a variety of measurements,
but the nature of its main ingredients, dark matter and dark energy, remains unknown. is a …

Aims. The eROSITA Final Equatorial-Depth Survey has been carried out during the
performance verification phase of the Spectrum-Roentgen-Gamma/eROSITA telescope and …

Stars that interact with supermassive black holes (SMBHs) can be either completely or
partially destroyed by tides. In a partial tidal disruption event (TDE), the high-density core of …

Most tidal disruption events (TDEs) are currently found in time-domain optical and soft X-ray
surveys, both of which are prone to significant obscuration. The infrared (IR), however, is a …

Context. In November 2019, eROSITA on board of the Spektrum-Roentgen-Gamma (SRG)
observatory started to map the entire sky in X-rays. After the four-year survey program, it will …

Context. During its all-sky survey, the extended ROentgen Survey with an Imaging
Telescope Array (eROSITA) on board the Spectrum-Roentgen-Gamma (SRG) observatory …
