Probing Quadratically Coupled Ultralight Dark Matter with the Laser Interferometer Space Antenna
Xucheng Gan, Hyungjin Kim, Anna-Malin Lemke +1
Ultralight dark matter can interact with Standard Model particles via gravitational and non-gravitational interactions. Through such interactions, it can leave distinctive signals…

Probing Quadratically Coupled Ultralight Dark Matter with Pulsar Timing Arrays
Xucheng Gan, Hyungjin Kim, Andrea Mitridate
Ultralight dark matter may couple quadratically to Standard Model particles. Such quadratic interactions give rise to both coherent and stochastic signals in pulsar timing array (P…

Stochastic Ultralight Dark Matter Fluctuations in Pulsar Timing Arrays
Hyungjin Kim, Andrea Mitridate
Metric perturbations induced by ultralight dark matter (ULDM) fields have long been identified as a potential target for pulsar timing array (PTA) observations. Previous works have…
