  • Viscous self interacting dark matter and cosmic acceleration 
    Atreya, Abhishek; Bhatt, Jitesh R.; Mishra, Arvind (IOP Publishing, 2018-02)
    Self interacting dark matter (SIDM) provides us with a consistent solution to certain astrophysical observations in conflict with collision-less cold DM paradigm. In this work we estimate the shear viscosity (η) and bulk ...
  • Viscous self interacting dark matter cosmology for small redshift 
    Atreya, Abhishek; Bhatt, Jitesh R.; Mishra, Arvind (IOP Publishing, 2019-02)
    The viscosity of dark matter in cosmological models may cause an accelerated expansion and when this effect is sufficiently large, it can explain the dark energy. In this work, attributing the origin of viscosity to ...
