Progenitor model of Cosmic Ray knee
Biplab Bijay, Arunava Bhadra
Primary energy spectrum of cosmic rays exhibits a knee at about PeV where a change in the spectral index occurs. Despite many efforts the origin of such a feature of the spectr…
Newtonian analogue of corresponding spacetime dynamics of rotating black holes: Implication on black hole accretion
Shubhrangshu Ghosh, Tamal Sarkar, Arunava Bhadra
Based on the conserved Hamiltonian for a test particle, we have formulated a Newtonian analogue of Kerr spacetime in the `low energy limit of the test particle motion' that, in pri…
Newtonian analogue of Schwarzschild de-Sitter spacetime: Influence on the local kinematics in galaxies
Tamal Sarkar, Shubhrangshu Ghosh, Arunava Bhadra
The late time accelerated expansion of the Universe demands that even in local galactic-scales it is desirable to study astrophysical phenomena, particularly relativistic accretion…
