Wave dark matter

L Hui - Annual Review of Astronomy and Astrophysics, 2021 - annualreviews.org
We review the physics and phenomenology of wave dark matter: a bosonic dark matter
candidate lighter than about 30 eV. Such particles have a de Broglie wavelength exceeding …

Axion dark matter: What is it and why now?

F Chadha-Day, J Ellis, DJE Marsh - Science advances, 2022 - science.org
The axion has emerged in recent years as a leading particle candidate to provide the
mysterious dark matter in the cosmos, as we review here for a general scientific audience …

Strong bound on canonical ultralight axion dark matter from the lyman-alpha forest

KK Rogers, HV Peiris - Physical Review Letters, 2021 - APS
We present a new bound on the ultralight axion (ULA) dark matter mass ma, using the
Lyman-alpha forest to look for suppressed cosmic structure growth: a 95% lower limit ma> …

Superradiant evolution of the shadow and photon ring of Sgr

Y Chen, R Roy, S Vagnozzi, L Visinelli - Physical Review D, 2022 - APS
Ultralight bosons can affect the dynamics of spinning black holes (BHs) via superradiant
instability, which can lead to a time evolution of the supermassive BH shadow. We study …

Ultra-light dark matter

EGM Ferreira - The Astronomy and Astrophysics Review, 2021 - Springer
Ultra-light dark matter is a class of dark matter models (DM), where DM is composed by
bosons with masses ranging from 10^-24\, eV< m< eV 10-24 eV< m< eV. These models …

Black hole superradiance of self-interacting scalar fields

M Baryakhtar, M Galanis, R Lasenby, O Simon - Physical Review D, 2021 - APS
Black hole superradiance is a powerful probe of light, weakly coupled hidden sector
particles. Many candidate particles, such as axions, generically have self-interactions that …

Precision metrology meets cosmology: improved constraints on ultralight dark matter from atom-cavity frequency comparisons

CJ Kennedy, E Oelker, JM Robinson, T Bothwell… - Physical Review Letters, 2020 - APS
We conduct frequency comparisons between a state-of-the-art strontium optical lattice clock,
a cryogenic crystalline silicon cavity, and a hydrogen maser to set new bounds on the …

Superradiance evolution of black hole shadows revisited

R Roy, S Vagnozzi, L Visinelli - Physical Review D, 2022 - APS
Black hole (BH) shadows can be used to probe new physics in the form of ultralight particles
via the phenomenon of superradiant instability. By directly affecting the BH mass and spin …
