Imprints of Higgs-portal fermionic dark matter on neutron-star tidal deformability and the mass-radius slope

Monmoy Molla, Mehedi Kalam, Tuhin Malik

We investigate the structure of neutron stars (NSs) admixed with fermionic dark matter (DM) using three density-dependent relativistic mean-field (DDRMF) functionals (DDME, DDB, an…
