Unified dark sector approaches to cosmological tensions
Sergio Sevillano Muñoz, Mark Trodden
We present an analytical study of minimal mass-varying dark matter models, in which a single scalar field controls the dark matter mass, focusing on their utility in simultaneously…
Cosmological Evidence for Dark Axion-Dark Baryon Interactions from Apparent Phantom Crossing
Justin Khoury, Meng-Xiang Lin, Mark Trodden
Interactions between dark matter and dark energy can lead to an apparent phantom-crossing behavior that mimics the expansion history preferred by the latest cosmological observatio…
Radial Solutions of Multi-Field de Sitter Galileons
Alice Garoffolo, Mary Gerhardinger, Kurt Hinterbichler +1
We study static, spherically symmetric screening solutions in the -invariant multi-field de Sitter Galileon theory, with matter couplings preserving the internal…
Hidden symmetries for tidal Love numbers: Generalities and applications to analog black holes
Valerio De Luca, Brandon Khek, Justin Khoury +1
Tidal Love numbers characterize the conservative, static response of compact objects to external tidal fields. Remarkably, these quantities vanish identically for asymptotically fl…
Scattering perspective on gravitational lensing
Mariana Carrillo Gonzalez, Valerio De Luca, Alice Garoffolo +2
Gravitational waves propagating across gravitational potentials undergo lensing effects that, in the wave-optics regime, manifest as frequency-dependent amplitude and phase modulat…
First astrometric constraints on parity-violation in the gravitational wave background
Santiago Jaraba, Sachiko Kuroyanagi, Qiuyue Liang +2
Astrometry, the precise measurement of stellar positions and velocities, offers a promising approach to probing the low-frequency stochastic gravitational wave background (SGWB). N…
