Halo structure and lensing signatures of a polytropic dark matter fluid

Marriam Naeem

We investigate whether a minimal effective pressure in the dark matter sector can modify nonlinear halo structure while preserving the successful large-scale predictions of the $Î…

Layered dark structure with a Structuring Field: A $Z_{4}$ -symmetric Inert Doublet-Singlet realization and implications for the $S_{8}$ tension

Marriam Naeem, Mohid Farhan

We introduce the Layered Dark Sectors with a Structuring Field (LDS-SF), a structured cosmological framework where the internal architecture of a multi-component dark sector natura…
