Sensitivity to dark sector scales from gravitational wave signatures

Dent, James B.; Dutta, Bhaskar; Ghosh, Sumit +2 more

We consider gravitational sound wave signals produced by a first-order phase transition in a theory with a generic renormalizable thermal effective potential of power law form. We find the frequency and amplitude of the gravitational wave signal can be related in a straightforward manner to the parameters of the thermal effective potential. This l…

How to search for mirror stars with Gaia

Matzner, Christopher D.; Curtin, David; Howe, Aaron +1 more

We show for the first time how to conduct a direct search for dark matter using Gaia observations. Its public astrometric data may contain the signals of mirror stars, exotic compact objects made of atomic dark matter with a tiny kinetic mixing between the dark and SM photon. Mirror stars capture small amounts of interstellar material in their cor…
