- **Fast flaring observed from XMMU J053108.3-690923 by eROSITA: a supergiant fast X-ray transient in the Large Magellanic Cloud**
- Supergiant fast X-ray transient system (SFXT) consists of a neutron star in orbit with a supergiant. The authors analyze the fast flaring light curves and hardness ratio of the spectrum obtained by eRosita and XMM-Newton and report the first direct evidence of the detection of such SFXT HMXB outside our galaxy in LMC.

- **Discovery of a Supercluster in the eROSITA Final Equatorial Depth Survey: X-ray Properties, Radio Halo, and Double Relics**
- During eRosita Performance Verification phase, a previously unknown supercluster consisting of a chain of eight galaxy clusters at z=0.36 has been detected. Upper limits on the electron number density and mass of the warm-hot intergalactic medium were given. The authors predict to detect ~ 450 superclusters in the eROSITA_DE region in future.

- **Tempestuous life beyond R_500: X-ray view on the Coma cluster with SRG/eROSITA. I. X-ray morphology, recent merger, and radio halo connection**
- Rich morphology around Coma clusters identified in the 20 ks X-ray image obtained during eRosita Performance Verification phase suggests a recent (on-going) merger with the NGC 4839 group. The gas in Coma clusters went through two shocks, one from the first passage and the other from the settling back to equilibrium.

- **A giant X-ray dust scattering ring around the black hole transient MAXI J1348-630 discovered with SRG/eROSITA**
- A giant dust scattering ring around the Black Hole transient MAXI J1348−630 has been first detected by eRosita. The dust scattering ring expands 0.3 deg within 6 months and enables the authors to give a precise measurement of the distance (3390 pc) and mass (~ 11 M_sun) of the transient.

- **Extreme ultra-soft X-ray variability in an eROSITA observation of the Narrow-Line Seyfert 1 Galaxy 1H 0707-495**
- The eRosita soft X-ray light curves of NLS1 galaxy 1H 0707-495 show significant variability in the form of a flux decrease by a factor of 58, while much less extreme in hard X-ray band and no strong variability in UV band. A model including relativistic reflection and a variable partial covering absorber is able to fit the spectra and provides a possible explanation for the extreme light-curve behaviour.

- **SRG/eROSITA uncovers the most X-ray luminous quasar at z>6**
- The authors report the discovery of the most luminous quasars at z>6 and the most distant known radio loud quasar at z=6.18, CFHQS J142952+544717, with eRosita. eRosita has the potential to detect many more such objects with enhanced X-ray emission at high-z and reveal the contribution of inverse compton scattering between CMB photons and relativistic electrons in the jets.
