Gravitational waves
- Philippe Jetzer (Univ. Zurich)
The ability to directly detect gravitational waves from merging binary
black holes gave us our first-ever access to the genuinely strong-field
dynamics of gravity. In 2017 a binary neutron star coalescence was also
observed, accompanied by a short gamma ray burst, thus corroborating the
link between the two. The discovery of an afterglow gave a glimpse of
the putative formation mechanism for a...
Recent gravitational wave (GW) detections with LIGO/Virgo opened a new window on
the Universe, unveiling the most violent catastrophic events in the cosmos. GW
astronomy is just in its infancy, the Laser Interferometer Space Antenna (LISA)
and Pulsar Timing Arrays (PTAs) will offer a complementary view of the GW
universe in a much more extended range of frequencies, from mHz down to nHz....
The gravitational waves from a neutron star binary inspiral carry unique information about fundamental physics in extreme conditions. I will discuss the imprints of the properties of neutron star matter on the gravitational waves, what we have learned from the neutron star binary inspiral event GW170817, and outline future prospects and challenges.
