X-ray Emission and Orientation of Selected PF Galaxy Clusters

Tugay, A. V.; Dylda, S. S.; Panko, E. A.

X-ray counterparts for 35 galaxy clusters contained in the PF catalogue of galaxy clusters and groups were found in XMM-Newton archive. 22 ones (all from ACO catalogue) have extended elliptic X-ray haloes appropriate for determination of orientation. Position angles and eccentricities were calculated and compared with cluster orientations optical …
