Can breakdown of perturbation in the $α$ -attractor inflation lead to PBH formation?

Chitrak Sarkar, Arunoday Sarkar, Basundhara Ghosh +1

With the basic $α$ -attractor potentials, we investigate an inflationary regime in the high- $k$ limit, where the cosmological perturbation breaks down due to large enhancement in th…

Intrinsic and extrinsic gravitational flexions

Eileen Sophie Giesel, Basundhara Ghosh, Bjoern Malte Schaefer

The topic of this paper is a generalisation of the linear model for intrinsic alignments of galaxies to intrinsic flexions: In this model, third moments of the brightness distribut…
