Light bosons, proposed as a possible solution to various problems in fundamental physics and cosmology1–3, include a broad class of candidates for physics beyond the standard model, such as dilatons and moduli4, wave dark matter5 and axion-like particles6. If light bosons exist in nature, they will spontaneously form ‘clouds’ by extracting rotational energy from rotating massive black holes through superradiance, a classical wave amplification process that has been studied for decades7,8.

Finding the Ultralight Boson from a Black Hole’s Ringdown
Solving the problem of dark matter remains one of the greatest unsolved mystery of fundamental physics. One possible dark matter candidate is the scalar ultralight boson, with mass « 1eV. If they
Searching for ultralight bosons with supermassive black hole ringdown
One class of competitive candidates for dark matter is ultralight bosons. If they exist, these bosons may form long-lived bosonic clouds surrounding rotating black holes via superradiant
Directed searches for gravitational waves from ultralight bosons
Gravitational-wave detectors can be used to search for yet-undiscovered ultralight bosons, including those conjectured to solve problems in particle physics, high-energy theory, and cosmology. In
Searching for ultralight bosons within spin measurements of a population of binary black hole mergers
Ultralight bosons can form clouds around rotating black holes if their Compton wavelength is comparable to the black hole size. The boson cloud spins down the black hole through a process called
Probing the nature of black holes: Deep in the mHz gravitational-wave sky
TLDR
Precision tests of black hole spacetimes with mHz-band gravitational-wave detectors will probe general relativity and fundamental physics in previously inaccessible regimes, and allow us to address some of these fundamental issues in the current understanding of nature.
Follow-up signals from superradiant instabilities of black hole merger remnants
Superradiant instabilities can trigger the formation of bosonic clouds around rotating black holes. If the bosonic field growth is sufficiently fast, these clouds could form shortly after a binary
Dynamic signatures of black hole binaries with superradiant clouds
Superradiant clouds may develop around a rotating black hole, if there is a bosonic field with Compton wavelength comparable to the size of the black hole. In this paper, we investigate the effects
Extreme dark matter tests with extreme mass ratio inspirals
Future space-based laser interferometry experiments such as LISA are expected to detect $\cal O$(100--1000) stellar-mass compact objects (e.g., black holes, neutron stars) falling into massive black
Tidal deformability of dressed black holes and tests of ultralight bosons in extended mass ranges
The deformability of a compact object under the presence of a tidal perturbation is encoded in the tidal Love numbers (TLNs), which vanish for isolated black holes in vacuum. We show that the TLNs of
Unique Multimessenger Signal of QCD Axion Dark Matter.
TLDR
The projected reach of the LISA interferometer and next-generation radio telescopes such as the Square Kilometre Array is studied to infer the dark matter density and, consequently, to predict the radio emission.

Probing ultralight bosons with binary black holes
We study the gravitational-wave (GW) signatures of clouds of ultralight bosons around black holes (BHs) in binary inspirals. These clouds, which are formed via superradiance instabilities for rapidly
Constraining the mass of dark photons and axion-like particles through black-hole superradiance
Ultralight bosons and axion-like particles appear naturally in different scenarios and could solve some long-standing puzzles. Their detection is challenging, and all direct methods hinge on unknown
Discovering the QCD Axion with Black Holes and Gravitational Waves
Advanced LIGO may be the first experiment to detect gravitational waves. Through superradiance of stellar black holes, it may also be the first experiment to discover the QCD axion with decay
Black holes as particle detectors: evolution of superradiant instabilities
Superradiant instabilities of spinning black holes can be used to impose strong constraints on ultralight bosons, thus turning black holes into effective particle detectors. However, very little is
Exploring the String Axiverse with Precision Black Hole Physics
It has recently been suggested that the presence of a plenitude of light axions, an Axiverse, is evidence for the extra dimensions of string theory. We discuss the observational consequences of these
Can environmental effects spoil precision gravitational-wave astrophysics?
[abridged abstract] No, within a broad class of scenarios. With the advent of gravitational-wave (GW) astronomy, environmental effects on the GW signal will eventually have to be quantified. Here we
Orbital fingerprints of ultralight scalar fields around black holes
Ultralight scalars have been predicted in a variety of scenarios, and advocated as a possible component of dark matter. These fields can form compact regular structures known as boson stars, or---in
Superradiance
Superradiance is a radiation enhancement process that involves dissipative systems. With a 60 year-old history, superradiance has played a prominent role in optics, quantum mechanics and especially
New probe of dark-matter properties: gravitational waves from an intermediate-mass black hole embedded in a dark-matter minispike.
TLDR
It is shown that the gravitational wave (GW) detectability strongly depends on the radial profile of the DM distribution and even to noninteracting DM, which can be used as a new and powerful probe into DM properties.
Gravitational waves as a probe of dark matter minispikes
Recent studies show that an intermediate mass black hole (IMBH) may develop a dark matter (DM) mini-halo according to some BH formation scenarios. We consider a binary system composed of an IMBH
