Gravitational collapse of Matter in the presence of Scalar field Dark energy

Priyanka Saha, Dipanjan Dey, Kaushik Bhattacharya

This study examines the gravitational collapse of an overdense dark matter region in a coupled scalar field dark energy scenario within a flat FLRW background. It finds that, depen…

Cosmological effect of coherent oscillation of ultralight scalar fields in a multicomponent universe

Priyanka Saha, Dipanjan Dey, Kaushik Bhattacharya

The idea that coherent oscillations of a scalar field, oscillating over a time period that is much shorter than the cosmological timescale, can exhibit cold dark matter (CDM) like…
