12. Search for long-duration bursts in LIGO/Virgo data

Astrophysical phenomena originating around the death of massive stars are predicted to generate minute-long gravitational-wave transients for which robust predictive models are not readily available.
As searches looking for such signals must rely on minimal assumptions, they are also sensitive to gravitational waves emitted from unpredicted sources and have strong potential for discovering as...

15. Stochastic searches with LIGO/Virgo

Kamiel Jansens (UAntwerp)

The stochastic searches of the LIGO/Virgo collaborations will be discussed. We start with a general introduction to the searches, the sources we might observe in the future and the different search-types that are performed. Afterwards we have a look at the current state of the art and the outlook when the latest results might be expected. In the second part of the presentation we will focus on...

24. Search for dark photons with continous wave methods

Andrew Miller (UCLouvain)

We adapt a method, originally developed for continuous gravitational-wave searches, to directly detect dark photon dark matter. The method involves optimally choosing the analysis coherence time as a function of the frequency band analyzed, such that all of the signal's power will be confined to one frequency bin during the observation time. We describe the dark photon signal in detail, and...

22. Resonant Electromagnetic Detection of High-Frequency Gravitational Waves from Planetary-mass Primordial Black Holes Mergers

André Füzfa (UNamur), Nicolas Herman (UNamur)

Electromagnetic detectors (and generators) of gravitational waves have been considered since the early 70s, besides of the mechanical detectors and laser interferometers. The so-called Gertsenshtein effect describes the generation of gravitational waves when light passes through some constant magnetic field. However, it is the reverse phenomena – electromagnetic waves arising when incoming...

14. Performance of custom chips for ET and LISA

Alberto Gatti (KULeuven), Ciana Barretto (KULeuven)

27/10/2020, 12:20

Advanced gravitational wave detectors operate under extreme conditions of temperature and/or radiation. We will discuss both the advantages and challenges of employing custom chips for these systems. Specific challenges are highlighted for the Einstein Telescope and LISA design cases with the current techniques and work done to ensure reliable performance in each of the environments.
