Lessons from axion dark matter for gravitational-wave physics
Prof. Dr. Camilo Garcia-Cely (IFIC Valencia, Spain)

A decade has passed since the groundbreaking detection of gravitational
waves, significantly advancing our understanding of the cosmos. While
most current research focuses on detecting gravitational waves at
frequencies below a few kHz, there is a growing interest in exploring
higher-frequency signals, particularly those of cosmological origin. In
the first part of my talk, I will explore the background for these
signals within the Standard Model, with a focus on the primary source on
Earth: the Sun's high-temperature plasma. I will draw a notable
connection to solar axions. In the second part, the discussion will turn
to experimental approaches for detecting high-frequency gravitational
waves, with particular attention to the potential of axion haloscopes as
well polarimetry techniques.
