Black Holes Inside and Out 2024: visions for the future of black hole physics
Niayesh Afshordi, Abhay Ashtekar, Enrico Barausse +27
The gravitational physics landscape is evolving rapidly, driven by our ability to study strong-field regions, in particular black holes. Black Holes Inside and Out gathered world e…
Tidal heating as a discriminator for horizons in equatorial eccentric extreme mass ratio inspirals
Sayak Datta, Richard Brito, Scott A. Hughes +2
Tidal heating in a binary black hole system is driven by the absorption of energy and angular momentum by the black hole's horizon. Previous works have shown that this phenomenon b…
Waveform Modelling for the Laser Interferometer Space Antenna
LISA Consortium Waveform Working Group, Niayesh Afshordi, Sarp Akçay +144
LISA, the Laser Interferometer Space Antenna, will usher in a new era in gravitational-wave astronomy. As the first anticipated space-based gravitational-wave detector, it will exp…
Relevance of Precession for Tests of the Black Hole No Hair Theorems
Nicholas Loutrel, Richard Brito, Andrea Maselli +1
The multipole moments of black holes in general relativity obey certain consistency relations known as the no-hair theorems. The details of this multipolar structure are imprinted…
Superradiant instabilities of massive bosons around exotic compact objects
Lihang Zhou, Richard Brito, Zhan-Feng Mai +1
Superradiantly unstable ultralight particles around a classical rotating black hole (BH) can form an exponentially growing bosonic cloud, which have been shown to provide an astrop…
Extreme mass-ratio inspirals into black holes surrounded by scalar clouds
Richard Brito, Shreya Shah
We study extreme mass-ratio binary systems in which a stellar mass compact object spirals into a supermassive black hole surrounded by a scalar cloud. Scalar clouds can form throug…

In this work we construct and analyse non-perturbative stationary and axially-symmetric black hole solutions in General Relativity coupled to an electromagnetic and an axion field.…
Photon Ring Astrometry for Superradiant Clouds
Yifan Chen, Xiao Xue, Richard Brito +1
Gravitational atoms produced from the superradiant extraction of rotational energy of spinning black holes can reach energy densities significantly higher than that of dark matter,…
New Horizons for Fundamental Physics with LISA
K. G. Arun, Enis Belgacem, Robert Benkel +138
The Laser Interferometer Space Antenna (LISA) has the potential to reveal wonders about the fundamental theory of nature at play in the extreme gravity regime, where the gravitatio…
Inspiralling compact objects with generic deformations
Nicholas Loutrel, Richard Brito, Andrea Maselli +1
Self-gravitating bodies can have an arbitrarily complex shape, which implies a much richer multipolar structure than that of a black hole in General Relativity. With this motivatio…
The Next Generation Global Gravitational Wave Observatory: The Science Book
Vicky Kalogera, B. S. Sathyaprakash, Matthew Bailes +88
The next generation of ground-based gravitational-wave detectors will observe coalescences of black holes and neutron stars throughout the cosmos, thousands of them with exceptiona…
Evaporating black holes: constraints on anomalous emission mechanisms
Chen Yuan, Richard Brito, Vitor Cardoso
Hawking radiation of astrophysical black holes is minute and thought to be unobservable. However, different mechanisms could contribute to an anomalously high emission rate: extra…

Chen Yuan, Richard Brito, Vitor Cardoso
Ultralight bosons are possible fundamental building blocks of nature, and promising dark matter candidates. They can trigger superradiant instabilities of spinning black holes (BHs…
Assessing the detectability of the secondary spin in extreme mass-ratio inspirals with fully-relativistic numerical waveforms
Gabriel Andres Piovano, Richard Brito, Andrea Maselli +1
Extreme mass-ratio inspirals~(EMRIs) detectable by the Laser Inteferometric Space Antenna~(LISA) are unique probes of astrophysics and fundamental physics. Parameter estimation for…
Constraints on quasi-normal-mode frequencies with LIGO-Virgo binary-black-hole observations
Abhirup Ghosh, Richard Brito, Alessandra Buonanno
The no-hair conjecture in General Relativity (GR) states that a Kerr black hole (BH) is completely described by its mass and spin. As a consequence, the complex quasi-normal-mode (…
