Dissipative Dark Energy can explain the DESI phantom crossing
Prolay Chanda, Subinoy Das, Suratna Das
DESI results preferring an evolving dark energy component that appears to cross the phantom-divide in the recent past has raised a lot of interest in exploring the nature of dark e…
DESI results: Hint towards coupled dark matter and dark energy
Amlan Chakraborty, Prolay K. Chanda, Subinoy Das +1
We investigate a scenario where a dark energy quintessence field with positive kinetic energy is coupled with dark matter. With two different self-interaction potentials for th…
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…
Early mass varying neutrino dark energy: Nugget formation and Hubble anomaly
Antareep Gogoi, Ravi Kumar Sharma, Prolay Chanda +1
We present a novel scenario, in which light ( few \rm{eV}) dark fermions (sterile neutrinos) interact with a scalar field like in mass varying neutrino dark energy theories.…
