Since the first direct detection of gravitational waves (GWs) in 2015,
Vorlage_Tagungswebseite_Nobody (1).png
we have opened an entirely new observation window into the Universe
(complementary to the electromagnetic spectrum, neutrinos, and cosmic rays),
heralding the era of multi-messenger astronomy with GWs. A wealth of scientific insights
has already been gained – but so much more is yet to be discovered!
The sensitivity of current GW detectors is so incredible that the quantum noise of
the employed ultra-stable laser light would be limiting. This necessitates the use
of non-classical (“squeezed”) light, which is already routinely employed in
the current (second) generation of detectors, e.g., aLIGO and AdVirgo.
Many additional noise sources, such as seismic and thermal noise,
pose further challenges for future (third-generation) detectors, e.g., the Einstein Telescope,
a planned underground GW observatory in Europe.
To learn more about our Universe, we must achieve ever-higher detection rates
for meaningful GW astronomy, which requires evergreater detection sensitivity
and larger detection bandwidth. In my talk, I will introduce the principle of
interferometric GW detection, highlight some of the advanced technologies (employed and under development), and shed light on the plans for future interferometric GW observatories.
Der öffentliche Abendvortrag ist offen für alle Tagungsteilnehmer:innen und die interessierte Öffentlichkeit. Der Eintritt ist frei und eine Registrierung zur Tagung ist nicht notwendig.
