  • First tidal disruption events discovered by SRG/eROSITA: X-ray/optical properties and X-ray luminosity function at z < 0.6 
    Sazonov S.; Gilfanov M.; Medvedev P.; Yao Y.; Khorunzhev G.; Semena A.; Sunyaev R.; Burenin R.; Lyapin A.; Meshcheryakov A.; Uskov G.; Zaznobin I.; Postnov K.A.; Dodin A.V.; Belinski A.A.; Cherepashchuk A.M.; Eselevich M.; Dodonov S.N.; Grokhovskaya A.A.; Kotov S.S.; Bikmaev I.F.; Zhuchkov R.Y.; Gumerov R.I.; Van Velzen S.; Kulkarni S. (2021)
    We present the first sample of tidal disruption events (TDEs) discovered during the SRG all-sky survey. These 13 events were selected among X-ray transients detected in the 0° < l < 180° hemisphere by eROSITA during its ...
  • High-accuracy redshift measurements for galaxy clusters at z < 0.45 based on SDSS-III photometry 
    Meshcheryakov A.; Glazkova V.; Gerasimov S.; Burenin R.; Khorunzhev G. (2015)
    © 2015, Pleiades Publishing, Inc. A new method for measuring the redshifts of galaxy clusters based on photometric SDSSIII data is presented. Highly accurate photo-z measurements for red-sequence galaxies using machine ...
  • Optical Identifications of Galaxy Clusters Among Objects from the Second Planck Catalogue of Sunyaev–Zeldovich Sources 
    Zaznobin I.; Burenin R.; Bikmaev I.; Khamitov I.; Khorunzhev G.; Konoplev V.; Eselevich M.; Afanasiev V.; Dodonov S.; Rubiño-Martín J.; Aghanim N.; Sunyaev R. (2019)
    © 2019, Pleiades Publishing, Inc. We present the results of optical identifications and spectroscopic redshift measurements for galaxy clusters from the second Planck catalogue of Sunyaev-Zeldovich sources. We used the ...
  • SRG/eROSITA uncovers the most X-ray luminous quasar at z &gt; 6 
    Medvedev P.; Sazonov S.; Gilfanov M.; Burenin R.; Khorunzhev G.; Meshcheryakov A.; Sunyaev R.; Bikmaev I.; Irtuganov E. (2020)
    © 2020 The Author(s). We report the discovery of X-ray emission from CFHQS J142952+544717, the most distant known radio-loud quasar at z = 6.18, on 2019 December 10-11 with the eROSITA telescope on board the SRG satellite ...
