A Brief Study of Dark Energy Accretion onto Schwarzschild Black Hole : Biswas-Roy-Biswas Type Redshift Parameterization is Chosen

Subhajit Pal, Sukanya Dutta, Ritabrata Biswas

In this letter, we have considered accretion of a particular type of Dark Energy model onto a Schwarzschild type black hole. Before using the model, the free parameters of the Dark…

Threshold Drop in Accretion Density if Dark Energy is Accreting onto a Supermassive Black Hole

Ritabrata Biswas, Sandip Dutta

Galactic structures are supposed to be formed out of dark matter clustering. Some examples of supermassive black holes in the central regions of high redshift galaxies say that the…
