"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.
