"Testing General Relativity with Gravitational Waves"
Prof.
Vitor Cardoso
(Niels Bohr Institute)
Abstract:
We celebrate a decade of gravitational
wave astronomy. One of the most remarkable achievements concerns tests of
General Relativity and of the nature of compact objects. Gravitational collapse
in Einstein’s theory leads to black holes, leaving behind a
geometry with light rings, ergoregions and
horizons. These peculiarities are responsible
for uniqueness properties and energy
extraction mechanisms that turn black holes into
ideal laboratories of strong gravity, of
particle physics (yes!) and of possible quantum-
gravity effects. I will review some of the
things we learned during the last ten years.
About the speaker:
Vitor Cardoso is a Bohr Professor and DNRF
Chair at the Niels Bohr Institute and
IST Distinguished Professor at Instituto
Superior Técnico. His research interests are
mainly focused on strong-gravity problems,
with implications for gravitational-wave
and black-hole physics, and he pioneered
black hole spectroscopy. He is co-author of
two books and of over 300 scientific
papers. His research was recognized by the
European Research Council, with three
prestigious ERC Grants. He was a Research
Fellow at CERN and Perimeter Institute,
and a Van der Waals Professorial Chair at Amsterdam. He Chaired the IST Physics
Department in 2020-2021 and the European
COST Action GWverse from 2017-2021, in a
network of over 500 scientists. He is a
member of the Lisbon Academy of Sciences,
and the 2023 ULisboa Award, the highest
honour conferred by the University of
Lisbon. He was awarded the
“Ordem de Sant’Iago da Espada”
presidential title, for scientific achievements.
