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 …

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 …

Excluding fuzzy dark matter with sizes and stellar kinematics of ultrafaint dwarf galaxies

N Dalal, A Kravtsov - Physical Review D, 2022 - APS
We use observations of ultrafaint dwarf (UFD) galaxies to constrain the particle mass of
ultralight dark matter. Potential fluctuations created by wave interference in virialized “fuzzy” …

Galactic rotation curves versus ultralight dark matter: A systematic comparison with SPARC data

N Bar, K Blum, C Sun - Physical Review D, 2022 - APS
We look for and place observational constraints on the imprint of ultralight dark matter
(ULDM) soliton cores in rotation-dominated galaxies. Extending previous analyses, we find …

Oscillations and random walk of the soliton core in a fuzzy dark matter halo

X Li, L Hui, TD Yavetz - Physical Review D, 2021 - APS
A fuzzy dark matter halo consists of a soliton core close to the center and a Navarro-Frenk-
White–like density profile in the outer region. Previous investigations found that the soliton …

Construction of wave dark matter halos: Numerical algorithm and analytical constraints

TD Yavetz, X Li, L Hui - Physical Review D, 2022 - APS
We present a wave generalization of the classic Schwarzschild method for constructing self-
consistent halos—such a halo consists of a suitable superposition of waves instead of …

Coherent and incoherent structures in fuzzy dark matter haloes

IK Liu, NP Proukakis… - Monthly Notices of the …, 2023 - academic.oup.com
We show that fuzzy dark matter haloes exhibit spatial differentiation in the coherence of the
field configuration, ranging from completely coherent in the central solitonic core to …

Soliton formation and the core-halo mass relation: An eigenstate perspective

JL Zagorac, E Kendall, N Padmanabhan, R Easther - Physical Review D, 2023 - APS
Ultralight dark matter (ULDM) is an axion-like dark matter candidate with an extremely small
particle mass. ULDM halos consist of a spherically symmetric solitonic core and an NFW-like …

Multifield ultralight dark matter

M Gosenca, A Eberhardt, Y Wang, B Eggemeier… - Physical Review D, 2023 - APS
Ultralight dark matter (ULDM) is usually taken to be a single scalar field. Here we explore the
possibility that ULDM consists of N light scalar fields with only gravitational interactions. This …

Binary supermassive black holes orbiting dark matter solitons: From the dual AGN in UGC4211 to nanoHertz gravitational waves

T Broadhurst, C Chen, T Liu, KF Zheng - arXiv preprint arXiv:2306.17821, 2023 - arxiv.org
We explore the orbital implications of the binary Supermassive Black Holes (SMBHs)
discovered in UGC4211, for the frequency spectrum of stochastic gravitational wave …
