Accelerated inference of microlensed gravitational waves with machine learning
Marienza Caldarola, Srashti Goyal, Nihar Gupte +2
Gravitational waves (GWs) within the LIGO-Virgo-KAGRA sensitivity band can be microlensed by stellar and intermediate-mass black holes, producing a frequency-dependent modulation o…
DESI constraints on two-field quintessence with exponential potentials
George Alestas, Marienza Caldarola, Indira Ocampo +2
We investigate a quintessence model involving two scalar fields with double-exponential potentials. This configuration allows the system as a whole to emulate the dynamics of a sin…
Updated constraints on modified gravity from binary pulsars
S. Bussieres, M. Caldarola, S. Nesseris
Binary pulsars offer a unique natural laboratory to test General Relativity (GR) and probe for deviations from its paradigm, as predicted by alternative theories of gravity. In thi…
Astrometric constraints on stochastic gravitational wave background with neural networks
Marienza Caldarola, Gonzalo Morrás, Santiago Jaraba +3
Astrometric measurements provide a unique avenue for constraining the stochastic gravitational wave background (SGWB). In this work, we investigate the application of two neural ne…
DESI constraints on -attractor inflationary models
George Alestas, Marienza Caldarola, Sachiko Kuroyanagi +1
The recent results on the baryon acoustic oscillations measurements from the DESI collaboration have shown tantalizing hints for a time-evolving dark energy equation of state param…
Mass octupole and current quadrupole corrections to gravitational wave emission from close hyperbolic encounters
Alexander Roskill, Marienza Caldarola, Sachiko Kuroyanagi +1
In this paper, we study the next-to-leading order corrections in the mass multipole expansion, i.e. the mass octupole and current quadrupole, to gravitational wave production by cl…
Effects of orbital precession on hyperbolic encounters
Marienza Caldarola, Sachiko Kuroyanagi, Savvas Nesseris +1
The hyperbolic encounters of two massive objects are characterized by the emission of a gravitational wave burst, with most of the energy released during the closest approach (near…
