Trails of clouds in binary black holes
Mateja Bošković, Rafael A. Porto, Matthias Koschnitzke
Superradiant instabilities of rotating black holes can give rise to long-lived bosonic clouds, offering natural laboratories to probe ultralight particles across a wide range of pa…
Signatures of ultralight bosons in the orbital eccentricity of binary black holes
Mateja Bošković, Matthias Koschnitzke, Rafael A. Porto
We show that the existence of clouds of ultralight particles surrounding black holes during their cosmological history as members of a binary system can leave a measurable imprint…
Gravitational signatures of ALP dark matter fragmentation
Aleksandr Chatrchyan, Cem Eröncel, Matthias Koschnitzke +1
The misalignment mechanism for axion-like particles (ALPs) is a leading explanation for dark matter. In this work we investigate ALPs with non-periodic potentials, which allow for…
ALP dark matter with non-periodic potentials: parametric resonance, halo formation and gravitational signatures
Aleksandr Chatrchyan, Cem Eröncel, Matthias Koschnitzke +1
Axion-like particles (ALPs) are leading candidates to explain the dark matter in the universe. Their production via the misalignment mechanism has been extensively studied for cosi…
