Astrophysics, cosmology and particle physics with large atom interferometers

Europe/Athens
Description
Atom inteferometers open up new perspectives in searches for dark matter and gravitational waves. They could detect very small interactions of ultralight bosonic dark matter with Standard Matter particles, including electrons, quarks and photons, and would be sensitive to gravitational waves in a range of frequencies intermediate between the ranges where LIGO, Virgo and the planned LISA space-borne laser interferometer are sensitive. This frequency range gives access to mergers of intermediate-mass black holes, and may provide insights into how the supermassive black holes in galactic nuclei have been formed. These scientific prospects will be reviewed in light of recent detections of nano-Herz gravitational waves by pulsar timing arrays and high-redshift black holes using JWST.
