Biases from Astrophysical Environmental Effects in Standard-Siren Cosmology
Ioannis Liodis, Rodrigo Vicente, Soumen Roy +1
Next-generation ground based gravitational wave detectors will enable precision standard-siren cosmology, making systematics increasingly important. We investigate how line-of-sigh…
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…
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…
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…
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…
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…
Probing the quantum nature of black holes with ultra-light boson environments
Soumodeep Mitra, Sumanta Chakraborty, Rodrigo Vicente +1
Quantum black holes (BHs), thought of as an excited multilevel system, can be effectively modelled by replacing an event horizon with a partially reflective membrane. This emergent…
First constraints on compact binary environments from LIGO-Virgo data
Giada Caneva Santoro, Soumen Roy, Rodrigo Vicente +4
The LIGO-Virgo analyses of signals from compact binary mergers observed so far have assumed isolated binary systems in a vacuum, neglecting the potential presence of astrophysical…
