Title: Cosmic Choreography and the Waltz of Black Holes: Gravitational Waves and the Laser Interferometer Space Antenna

Abstract: The Universe, as described by the standard model of Cosmology, is a vast Erebos including dark matter and dark energy, with only a trace of luminous matter giving rise to the cosmic web we observe today. Yet, this seemingly insubstantial fraction has shaped galaxies, clusters, and filaments across billions of years. What remains largely invisible, however, may hold the key to unlocking some of the Universe’s deepest secrets. Dark matter, inferred from gravitational signatures like structure formation, galactic lensing and their corresponding rotation curves, continues to elude direct detection. But a new frontier has opened up: the realm of gravitational-wave physics. With detectors now regularly capturing the ripples in spacetime from black-hole binaries, as well as the launch of new space-borne detectors like the Laser Interferometer Space Antenna, a powerful bridge is emerging between generic astrophysical environments around non-vacuum black holes and their corresponding gravitational-wave emission. This talk explores how gravitational waves-long studied under the assumption of a vacuum spacetime-can be influenced by their astrophysical surroundings, particularly dark matter halos. I will present cutting-edge research on how these subtle environmental effects can leave fingerprints on gravitational-wave signals, offering a promising pathway to probe the nature and constrain dark matter models through a new observational channel.
