Formation and Abundance of Late Forming Primordial Black Holes as Dark Matter
Amlan Chakraborty, Prolay K Chanda, Kanhaiya Lal Pandey +1
We propose a novel mechanism where Primordial Black Hole (PBH) dark matter is formed much later in the history of the universe between the epoch of Big Bang Nucleosynthesis (BBN) a…
Signatures of Light Massive Relics on nonlinear structure formation
Arka Banerjee, Subinoy Das, Anshuman Maharana +1
Cosmologies with Light Massive Relics (LiMRs) as a subdominant component of the dark sector are well-motivated from a particle physics perspective, and can also have implications f…
Implications of an extended dark energy model with massive neutrinos
Ravi Kumar Sharma, Kanhaiya Lal Pandey, Subinoy Das
Recently there has been reports of finding a lower bound on the neutrino mass parameter () when using ACT and SPTpol data however these bounds on the are still weaker…
A Faster Growth of Perturbations in an Early Matter Dominated Epoch: Primordial Black Holes and Gravitational Waves
Subinoy Das, Anshuman Maharana, Francesco Muia
We present a scenario for fast growth of cosmological perturbations; , being the scale factor, with for the numerical examples reported in this ar…
