Troubles mounting for multipolar dark matter
read the original abstract
In this paper, we revisit the experimental constraints on the multipolar dark matter that has derivative coupling to the visible sector mediated by the Standard Model photon. The momentum dependent interaction enables them to be captured efficiently within massive celestial bodies boosted by their steep gravitational potential. This phenomena makes compact celestial bodies as an efficient target to probe such type of dark matter candidates. We demonstrate that a synergy of the updated direct detection results from DarkSide-50 and LUX-ZEPLIN together with IceCube bounds on high energy solar neutrinos from dark matter capture disfavour the viable parameter space of the dipolar dark matter scenario. Whereas, for the anapole dark matter scenario, a narrow window survives that lies within the reach of prospective heating signals due to the capture of dark matter at cold neutron stars.

Multipolar Dark Matter Freeze-out in an Early Matter-Dominated Universe
Entropy dilution from early matter domination reduces the couplings needed for multipolar dark matter to match the observed relic density, reopening regions excluded under radiation domination.

Neutron stars as thermometers for reheating induced dipole dark matter
Dipole dark matter produced by freeze-out or freeze-in, including entropy dilution from reheating, can be probed via neutron star heating due to momentum-dependent electromagnetic interactions.
