Measurement of the Orbital Period of the X-ray Burster GS 1826-238 Based on Observations of Its Optical Brightness Variations

Meshcheryakov A.; Revnivtsev M.; Pavlinsky M.; Khamitov I.; Bikmaev I. (2010)

The variability of the optical and X-ray fluxes from the binary GS 1826-238 is investigated. An epoch-folding analysis of the optical data obtained with the RTT-150 telescope in 2003-2004 has revealed periodic brightness ...
Optical Identification of Candidates for Active Galactic Nuclei Detected by the Mikhail Pavlinsky ART-XC Telescope Onboard the SRG Observatory during an All-Sky X-ray Survey

Zaznobin I.A.; Uskov G.S.; Sazonov S.Y.; Burenin R.A.; Medvedev P.S.; Khorunzhev G.A.; Lyapin A.R.; Krivonos R.A.; Filippova E.V.; Gilfanov M.R.; Sunyaev R.A.; Eselevich M.V.; Bikmaev I.F.; Irtuganov E.N.; Nikolaeva E.A. (2021)

Abstract: We present the results of our identification of eight objects from the preliminary catalogue of X-ray sources detected in the 4–12 keV energy band by the Mikhail Pavlinsky ART-XC telescope onboard the SRG observatory ...
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 ...
Redshift Measurements for Galaxies in Clusters by Multislit Spectroscopy at the 1.5-m Telescope RTT150

Khamitov I.M.; Bikmaev I.F.; Burenin R.A.; Glushkov M.V.; Melnikov S.S.; Lyapin A.R. (2020)

© 2020, Pleiades Publishing, Inc. Abstract: An example of simultaneous spectroscopic redshift measurements for a large number of galaxies in a cluster by multiobject spectroscopy with the medium- and low-resolution TFOSC ...
Spectroscopic Redshift Measurements for Galaxy Clusters Detected in the Planck All-Sky Survey

Zaznobin I.A.; Burenin R.A.; Bikmaev I.F.; Khamitov I.M.; Khorunzhev G.A.; Lyapin A.R.; Eselevich M.V.; Afanasiev V.L.; Dodonov S.N.; Sunyaev R.A. (2020)

© 2020, Pleiades Publishing, Ltd. Abstract: We present the results of spectroscopic redshift measurements for galaxy clusters from the catalogue compiled previously from Planck all-sky survey data in combination with Sloan ...
Spectroscopic Redshift Measurements for Galaxy Clusters from the Planck Survey and Observations of These Clusters in the SRG/eROSITA Survey

Zaznobin I.A.; Burenin R.A.; Bikmaev I.F.; Khamitov I.M.; Khorunzhev G.A.; Lyapin A.R.; Eselevich M.V.; Lyskova N.S.; Medvedev P.S.; Gilfanov M.R.; Sunyaev R.A. (2021)

Abstract: We present the results of our spectroscopic redshift measurements for galaxy clusters detected previously from Planck all-sky survey data as well as Sloan Digital Sky Survey and WISE all-sky survey data. The ...
