Seeds of supermassive black holes in general relativistic and alternative cosmologies: Implications of massive seeds

Nirmali Das, Sanjeev Kalita, Ankita Kakati

Presence of supermassive black holes (SMBHs) with mass $(1 0^{6} - 1 0^{9}) M_{⊙}$ at $z = 10$ has been recently revealed by James Webb Space Telescope (JWST) observations. In this…

Constraining primordial black hole masses through $f (R)$ gravity scalarons in Big Bang Nucleosynthesis

Abhijit Talukdar, Sanjeev Kalita, Nirmali Das +1

Big Bang Nucleosynthesis (BBN) is a strong probe for constraining new physics including gravitation. $f (R)$ gravity theory is an interesting alternative to general relativity which…
