Ultralight Dark Matter Search with Space-Time Separated Atomic Clocks and Cavities
Melina Filzinger, Ashlee R. Caddell, Dhruv Jani +4
We devise and demonstrate a method to search for non-gravitational couplings of ultralight dark matter to standard model particles using space-time separated atomic clocks and cavi…
An effective description of Laniakea: impact on cosmology and the local determination of the Hubble constant
L. Giani, C. Howlett, K. Said +2
We propose an effective model to describe the bias induced on cosmological observables by Laniakea, the gravitational supercluster hosting the Milky Way, which was defined using pe…
Bayesian analysis of a Unified Dark Matter model with transition: can it alleviate the tension?
Emmanuel Frion, David Camarena, Leonardo Giani +4
We consider cosmological models in which Dark Matter (DM) and Dark Energy (DE) are described by a single component, dubbed Unified Dark Matter (UDM) models, in which the DE-like pa…
Induced non-local cosmology
Leonardo Giani, Oliver Fabio Piattella
We investigate the cosmological implications of an effective gravitational action, inspired by Sakharov's idea of induced gravity, containing non-local contributions from the opera…
Can Einstein (rings) surf Gravitational Waves?
Leonardo Giani, Cullan Howlett, Tamara M. Davis
How does the appearance of a strongly lensed system change if a gravitational wave is produced by the lens? In this work we address this question by considering a supermassive blac…
Cross-correlating radial peculiar velocities and CMB lensing convergence
Leonardo Giani, Cullan Howlett, Rossana Ruggeri +3
We study, for the first time, the cross correlation between the angular distribution of radial peculiar velocities (PV) and the lensing convergence of cosmic microwave background (…
