Identification of Radio and Gamma-ray Pulsars in X-rays Using Data from the SRG/eROSITA All-Sky Survey

We have identified the radio and gamma-ray pulsars known in the eastern half of the sky in the soft X-ray band using data from the all-sky X-ray survey performed by the eROSITA telescope onboard the Spectrum–Roentgen–Gamma observatory. As a result, we have found new candidate counterparts for 12 pulsars of different ages and types at a confidence level $${\gtrsim}3\sigma$$ . A comparable number has been previously identified in the western half of the sky. In total, this accounts for about 12 $$\%$$ of the number of known pulsars that have already been detected in X-rays. We give estimates of the X-ray fluxes from the new counterparts, preliminary characteristics of their X-ray spectra, and brief descriptions of the properties of the pulsars themselves. The telescope has also detected 56 pulsars in the eastern half of the sky previously identified in X-rays by other observatories.

Abstract

We have identified the radio and gamma-ray pulsars known in the eastern half of the sky in the soft X-ray band using data from the all-sky X-ray survey performed by the eROSITA telescope onboard the Spectrum–Roentgen–Gamma observatory. As a result, we have found new candidate counterparts for 12 pulsars of different ages and types at a confidence level $${\gtrsim}3\sigma$$ . A comparable number has been previously identified in the western half of the sky. In total, this accounts for about 12 $$\%$$ of the number of known pulsars that have already been detected in X-rays. We give estimates of the X-ray fluxes from the new counterparts, preliminary characteristics of their X-ray spectra, and brief descriptions of the properties of the pulsars themselves. The telescope has also detected 56 pulsars in the eastern half of the sky previously identified in X-rays by other observatories.
