Prospects of Probing Dark Matter Condensates with Gravitational Waves

Understand

The Lambda-Cold Dark Matter model explains cosmological observations most accurately till date.

• However, it is still plagued with various shortcomings at galactic scales.
• Models of dark matter such as superfluid dark matter, Bose-Einstein Condensate(BEC) dark matter and fuzzy dark matter have been proposed to overcome some of these drawbacks.
• In this work, we probe these models using the current constraint on the gravitational wave (GW) propagation speed coming from the binary neutron star GW170817 detection by LIGO-Virgo detector network and use it to study the allowed parameter space for these three models for Advanced LIGO+Virgo, LISA, IPTA and SKA detection frequencies.
