    • Optical substructure and BCG offsets of Sunyaev–Zel’dovich and X-ray-selected galaxy clusters 

      Lopes, Paulo Afrânio Augusto; Trevisan, Marina; Laganá, Tatiana Ferraz; Durret, Florence; Ribeiro, Andre Luis Batista; Rembold, Sandro Barboza (2018) [Journal article]
      We used optical imaging and spectroscopic data to derive substructure estimates for local Universe (z < 0.11) galaxy clusters from two different samples. The first was selected through the Sunyaev–Zel’dovich (SZ) effect ...

    • Weak lensing and spectroscopic analysis of the nearby dissociative merging galaxy cluster Abell 3376 

      Oliveira, Rogério Monteiro de; Lima Neto, Gastão Cesar Bierrenbach; Cypriano, Eduardo Serra; Machado, Rubens Eduardo Garcia; Capelato, Hugo Vicente; Laganá, Tatiana Ferraz; Durret, Florence; Bagchi, Joydeep (2017) [Journal article]
      The galaxy cluster Abell 3376 is a nearby (¯z = 0.046) dissociative merging cluster surrounded by two prominent radio relics and showing an X-ray comet-like morphology. The merger system is comprised of the subclusters ...
