  • Chandra observations of ten galaxy clusters 
    Babyk, Iu.; Melnyk, O.; Elyiv, A. (Advances in Astronomy and Space Physics, 2012)
    In the present study the X-ray properties of 10 galaxy clusters (CL0024+17, RXJ1347.5+1145, A223, A521, A611, A697, A907, A1204, A1413 and A2744) are analysed using the archival X-ray data of the Chandra observatory. The ...
  • Criteria for galaxy classification in SDSS 
    Dobrycheva, D.; Melnyk, O. (Advances in Astronomy and Space Physics, 2012)
    We considered the sample of galaxy pairs collected from SDSS DR5. At first we made a morphological classification of approximately 1100 galaxies by visual inspection. As it is known the galaxy morphological types strongly ...
  • The distribution of dark matter and intracluster gas in galaxy clusters 
    Babyk, Iu.; Melnyk, O.; Elyiv, A. (Advances in Astronomy and Space Physics, 2012)
    We present the temperature radial profiles of intracluster gas, and the radial profiles of density and mass for dark matter and intracluster gas for five galaxy clusters: Abell 1413, Abell 1204, Abell 2744, Abell 223 and ...
