How will we detect gravitational waves 15 years from now? by Dr. J. van Heijningen

With the first detection of gravitational waves (GWs), the most precise distance measurement ever was made. The first coincidental measurement of GWs with electromagnetic counterparts, GW170817, from a binary neutron star merger has provided a firm basis for the newly founded field of multi-messenger gravitational wave astronomy. Future GW detectors will give access to more (distant) detections and heavier mass black hole inspiral signals. I will discuss GW detector operation and the latest signals that we detected. Then, an overview of future GW detectors, including space based detectors, will be given and I will focus on the European proposal for a future GW detector: the Einstein Telescope <https://www.einsteintelescope.nl/en/>. Before we can ask funding for this 1.5-2 billion euro (!) project, lots of R&D needs to be performed to prototype new technologies. Especially the fact that we plan to cool our mirrors, i.e. 100s of kg silicon cylinders, down to 10 K changes everything. Two prototype facilities are currently being constructed in Maastricht and Liège. Additionally, I will briefly touch upon my personal quest of developing a cryogenic superconducting accelerometer. Lastly, a short description and advertisement of a project at UCLouvain for which we seek a PhD candidate is given.

Bio Dr. J. van Heijningen

Joris is an experienced instrumental researcher that has worked in nuclear physics, particle physics and gravitational waves. He did his B.Sc. and M.Sc. Applied Physics at the TU Delft and worked at CERN, Stanford University/SLAC and the Virgo and KAGRA GW observatories. The highlight of his Ph.D. at Nikhef, Amsterdam, has been the development of the world’s most sensitive inertial sensor. Additionally, the timing of the first detection of GWs gave ample opportunities for outreach. In his case, that led to many public seminars and a Klokhuis appearance <https://www.hetklokhuis.nl/tvuitzending/4164/Zwaartekrachtsgolven>. Within the field of GWs, Joris is an expert in vibration isolation, inertial sensing and optical mode matching. After a postdoc at the University of Western Australia, he is now a research scientist at UCLouvain working on projects for Einstein Telescope and Advanced Virgo.
