Scalar fields around black hole binaries in LIGO-Virgo-KAGRA
Soumen Roy, Rodrigo Vicente, Josu C. Aurrekoetxea +2
Light scalar particles arise naturally in many extensions of the Standard Model and are compelling dark-matter candidates. Gravitational interactions near black holes can trigger t…
The COSMIC WISPers White Paper: The physics case for Weakly Interacting Slim Particles
Ariel Arza, Deniz Aybas, Shyam Balaji +124
Axions and other very weakly interacting slim particles (WISPs), with masses below 1 GeV, arise naturally in many extensions of the Standard Model of particle physics. In particula…
Constraints on Dark Matter Structures around Gaia Black Holes
Nuno P. Branco, Ricardo Z. Ferreira, João G. Rosa +1
We demonstrate that Gaia's detection of stars on wide orbits around black holes opens a new observational window on dark matter structures -- such as scalar clouds and dark matter…
Searching for ultra-light dark matter through frequency modulation of gravitational waves
Diego Blas, Silvia Gasparotto, Rodrigo Vicente
Ultra-light bosons, naturally appearing in well-motivated extensions to the Standard Model, can constitute all the dark matter. Models with particle mass close to the smallest phen…
Compact Binary Coalescences in Dense Gaseous Environments Can Pose as ones in Vacuum
Soumen Roy, Rodrigo Vicente
The gravitational-wave events observed by the LIGO-Virgo-KAGRA collaboration are attributed to compact binary coalescences happening in vacuum. However, several studies suggest tha…
