Optimising ultra-light dark matter searches with ground-based interferometers
Paola C. M. Delgado, Ornella J. Piccinni, Federico R. Urban
Ultra-light dark matter fields induce nearly monochromatic signals in gravitational-wave detectors through their coupling to the Standard Model. Their spectral morphology exhibits…
Dark graviton sensing with magnetically levitated superconductors
Valentina Danieli, Paola C. M. Delgado, Federico R. Urban
Levitated sensors have emerged as a new frontier to detect ultra-light dark matter such as axion-like particles and dark photons. In this work we study how a magnetically levitated…
Testing gravitational wave polarizations with LISA
Shingo Akama, Maxence Corman, Paola C. M. Delgado +16
In this paper we quantify the ability of the Laser Interferometer Space Antenna (LISA) to test the presence of non-tensorial polarizations as well as modifications to the tensor on…
Constraining the Gravitational Wave Speed in the Early Universe via Gravitational Cherenkov Radiation
Paola C. M. Delgado, Alexander Ganz, Chunshan Lin +1
Scalar particles traveling faster than a subluminal gravitational wave generate gravitons via gravitational Cherenkov radiation. In this paper, we investigate graviton production b…
