  • Evolution of the M•-σ relation 
    Bhattacharyya, D; Mangalam, A (Cambridge University Press, 2018-05)
    Black holes at the centers of the galaxies grow mainly by the processes of accretion, mergers, and consumption of stars. In the case of gas accretion with cooling sources, the flow is momentum driven, after which the black ...
  • M∙ − σ relation in spherical systems 
    Bhattacharyya, D; Mangalam, A (Indian Academy of Sciences, 2018-02)
    To investigate the M∙−σ relation, we consider realistic elliptical galaxy profiles that are taken to follow a single power-law density profile given by Ï (r)=Ï 0(r/r0)−γ or the Nuker intensity profile. We calculate ...
