Exploring the self interacting dark matter properties from low redshift observations
Abstract We calculate the shear ( $$\eta $$ η ) and bulk viscosity ( $$\zeta $$ ζ ) of Self Interacting Dark Matter (SIDM) fluid using the kinetic theory formalism. Using the astrophysical constraints on dark matter self-interaction cross section over mass $$ \sigma /m $$ σ / m , we demonstrate that...
