Summer Fellowships '23 Presentations 2/2

by Claudi Vall (UB Student), Àlex Garcia (UB Student)

Wednesday 29 Nov 2023, 13:00 → 14:00 Europe/Madrid

IFAE Seminar Room (IFAE)

The IFAE Summer Fellowship Programme offers undergraduate students the possibility of spending the summer as a physics researcher. The program has been running for 7 years now.

In this seminar, 2 students will report on their work done in this one-month stay.

Electromagnetic cavities as gravitational waves detectors: theoretical background and optimal configuration for Earth's rotation

Claudi Vall and Àlex Garcia, UB Students

Up to date, gravitational waves can be detected by huge interferometers and resonant Weber bars, among other methods. Another smaller method is achieved by using an electromagnetic cavity (MAGO), which generates electric signals with significantly reduced electromagnetic noise when a high-frequency gravitational waves arrives.
In this talk, we will explain the physical background of the experimental setup before studying the effect of the Earth's rotation and the optimal configuration for covering the maximum solid angle of the sky. Finally, we will show the novel and unexpected dependence of the method's sensitivity on the incoming gravitational wave's polarization, which contradicts the original MAGO 2.0 work.
