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 …

A search for ultralight axions using precision cosmological data

R Hlozek, D Grin, DJE Marsh, PG Ferreira - Physical Review D, 2015 - APS
Ultralight axions (ULAs) with masses in the range 1 0-33 eV≤ ma≤ 1 0-20 eV are motivated
by string theory and might contribute to either the dark-matter or dark-energy densities of the …

The imitation game: Proca stars that can mimic the Schwarzschild shadow

CAR Herdeiro, AM Pombo, E Radu… - … of Cosmology and …, 2021 - iopscience.iop.org
Can a dynamically robust bosonic star (BS) produce an (effective) shadow that mimics that
of a black hole (BH)? We focus on models of spherical BSs with free scalar or vector fields …

Shadows of Kerr black holes with scalar hair

PVP Cunha, CAR Herdeiro, E Radu, HF Rúnarsson - Physical review letters, 2015 - APS
Using backwards ray tracing, we study the shadows of Kerr black holes with scalar hair
(KBHSH). KBHSH interpolate continuously between Kerr BHs and boson stars (BSs), so we …

Bosonic dark matter in neutron stars and its effect on gravitational wave signal

D Rafiei Karkevandi, S Shakeri, V Sagun, O Ivanytskyi - Physical Review D, 2022 - APS
We study an impact of self-interacting bosonic dark matter (DM) on various observable
properties of neutron stars (NSs). The analysis is performed for asymmetric DM with masses …

Galaxy formation with BECDM–I. Turbulence and relaxation of idealized haloes

P Mocz, M Vogelsberger, VH Robles… - Monthly Notices of …, 2017 - academic.oup.com
We present a theoretical analysis of some unexplored aspects of relaxed Bose–Einstein
condensate dark matter (BECDM) haloes. This type of ultralight bosonic scalar field dark …

Boson stars and oscillatons: A review

L Visinelli - International Journal of Modern Physics D, 2021 - World Scientific
Compact objects occupy a pivotal role in the exploration of Nature. The interest spans from
the role of compact objects in astrophysics to their detection through various methods …

Constraining the mass of dark photons and axion-like particles through black-hole superradiance

V Cardoso, ÓJC Dias, GS Hartnett… - … of Cosmology and …, 2018 - iopscience.iop.org
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 …
