A series of talks on selected topics in physics and related scientific fields is delivered online by experts in their fields. Given the current situation on the ground in Palestine which makes holding in-person scientific activities almost impossible; the ICTP Physics Without Frontiers (PWF) in Trieste, Italy is collaborating with the UNESCO Chair in Mathematics and Theoretical Physics at Birzeit University in Palestine to organize a series of online talks delivered by experts in their fields addressing the latest developments in topics such as High Energy, Cosmology, Particle Physics, Artificial Intelligence, Machine Learning,… etc. The talks are presented in accessible and interactive way to students at Master level in Physics and related scientific topics with invitations to all interested students and faculty to join. On October 29th, at 13:00 CEST, Dr. Killian Martineau from Laboratory of Subatomic Physics and Cosmology in Grenoble will give a talk entitled: Some aspects of gravitational wave searches above 10 kHz Abstract: Gravitational waves signals are now part of the astrophysical landscape. They are currently observed in the Hz - ~10kHz range and evidences for a stochastic background have also been provided at much lower frequencies. While many efforts are devoted to the search of those waves at low frequencies, the high frequency regime remains vastly unexplored. During this presentation I will introduce the main goals and challenges associated with the search for gravitational waves above 10 kHz. Notably, I will focus on primordial black-holes as sources and discuss the signal they are expected to generate in resonant cavities operating at the GHz.
