| contents | Using the data from the all-sky survey in soft X-rays performed by the eROSITA telescope onboard the Spectrum-Roentgen-Gamma observatory we identified known radio and $γ$-ray pulsars in the eastern half of the sky. As a result, new candidate counterparts were found for twelve pulsars of different ages and types at a $\gtrsim$ 3$σ$ confidence level. A comparable number had been previously identified in the western half of the sky. In total, this represents about 12\% of all known pulsars already detected in X-rays. For the new counterparts, we provide estimates of their X-ray fluxes, preliminary characteristics of their X-ray spectra, and brief descriptions of the pulsars' properties. In addition, in the eastern half of the sky eROSITA detected 55 pulsars previously identified in X-rays by other telescopes. |
