"Gravitational-Wave Astronomy: Theoretical Advances and Challenges"

 

                                           Prof. Alessandra Buonanno

               (Max Planck Institute for Gravitational Physics (Albert Einstein Institute))

 

Abstract:

 

Since the first detection of gravitational waves from a binary

black-hole merger in 2015, the LIGO and Virgo detectors have observed

nearly 100 gravitational-wave signals from mergers of black holes, neutron

stars and their mixture. These observations rely on precise theoretical

predictions of the relativistic two-body dynamics and gravitational

radiation. After reviewing the synergistic approach that successfully

combines analytical and numerical relativity to produce accurate waveform

models, I will discuss the astrophysical and fundamental physics

properties that those models have allowed us to extract from

gravitational-wave observations, and highlight the theoretical challenges

that lie ahead to fully exploit the discovery potential of increasingly

sensitive detectors on the ground, such as Cosmic Explorer and Einstein

Telescope, and in space, such as LISA.

 

About the speaker:

 

Prof. Buonanno is a director at the Max Planck Institute for Gravitational

Physics (Albert Einstein Institute). She studied theoretical physics in

Pisa, and held faculty positions in Paris and at the University of

Maryland. She is a Principal Investigator of the LIGO Scientific

Collaboration, and a member of the LISA Consortium Board. For her

contributions to LIGO and Virgo discoveries, she was awarded the 2018

Gottfried Wilhelm Leibniz prize – the most prestigious research prize in

Germany. In 2021 she was co-awarded the Galileo Galilei Medal, the Dirac

Medal and the Balzan Prize, and soon after, the 2022 Tomalla Prize. She is

an elected member of the German National Academy of Sciences Leopoldina,

of the US National Academy of Sciences, of the Berlin-Brandenburg Academy

of Sciences and Humanities, and of the Italian National Academy of

Sciences. Buonanno is a Fellow of the International Society on General

Relativity and Gravitation, and of the American Physical Society. She

holds a research professorship at the University of Maryland, and honorary

professorships at the Humboldt University in Berlin, and at the University

of Potsdam.
