    • Clustering algorithms: sensitivity of mass determination using A 3581 

      Wilson, S.; Oozeer, N.; Loubser, S.I. (Wiley-VCH, 2013)
      In this paper we discuss various methods for clustering in order to determine estimates of the cluster mass, focusing on the cluster A3581. Using virtual observatory (VO) tools, possible galaxy cluster candidates are ...
    • X-ray and gamma-ray variability of NGC 1275 

      Chitnis, Varsha; Chandra, Sunil; Shukla, Amit; Singh, K.P.; Jayashree, Roy (MDPI, 2020)
      Gamma-ray emission from the bright radio source 3C 84, associated with the Perseus cluster, is ascribed to the radio galaxy NGC 1275 residing at the centre of the cluster. Study of the correlated X-ray/gamma-ray emission ...
