Emergent gravity from Michel flow with position dependent adiabatic index
Apashanka Das, Souvik Ghose, Tapas K. Das
Spherically symmetric, general relativistic Bondi accretion is known as the Michel flow. The stationary integral transonic solutions for the Michel flow has been constructed for mu…
Emergent gravity from nonlinear perturbation of spherical accretion with variable adiabatic index
Rohit Ghosh, Souvik Ghose, Biplab Raychaudhuri +2
The main aim of the present work is to demonstrate that the analogue gravity phenomena are not an artifact of linear perturbation, rather gravity-like effects emerge through the no…
Galaxy evolution in the cosmic web: the relative impact of nodes and filaments in the EAGLE simulation
Suman Sarkar, Biswajit Pandey, Apashanka Das
Galaxies evolve within the intricate geometry of the cosmic web, yet the distinct roles of its primary components - nodes and filaments remain incompletely understood. Using the EA…
The long road to the Green Valley: Tracing the evolution of the Green Valley galaxies in the EAGLE simulation
Apashanka Das, Biswajit Pandey
We study the evolution of the progenitors of the present-day Green Valley (GV) galaxies across redshift using data from the EAGLE simulations. We identify the present-day…
