To Stack or Not to Stack? Jacobian Conditioning and the Benefits of Depth in Metasurface-Based Linear Transformation Synthesis
Andrea Abrardo, Andrea Garulli
This paper investigates when and why stacking programmable metasurfaces into Stacked Intelligent Metasurfaces (SIMs) improves linear transformation synthesis at a fixed phase-contr…
Architecture Acceleration of Machine Learning Gravitational Waveform Surrogate Models
Adriano Frattale Mascioli, Lorenzo Piccari, Saulo Albuquerque +9
Accurate and computationally efficient waveform models of compact binary coalescences are a fundamental requirement for gravitational wave data analysis. This work presents differe…
Constraining primordial non-Gaussianity and parity-violation through Scalar-Induced Gravitational Waves with next-generation ground-based interferometers
Ilaria Caporali, H. V. Ragavendra, Angelo Ricciardone +1
In this work, we investigate the prospects for probing primordial non-Gaussianity and associated symmetry of parity through scalar-induced gravitational waves (SIGWs), with third-g…
Exploring Gravitational Wave Signatures Due to Primordial Non-gaussianity and Large Scale Structure Using SKAO
H. V. Ragavendra, Giulia Capurri, Alina Mierna +8
This chapter explores theoretical and observational strategies to use the stochastic gravitational-wave background detectable by Square Kilometre Array Observatory (SKAO) as a prob…
Tracing Primordial Gravitational Waves via non-Gaussian Signatures of Halo Bias
Mariam Abdelaziz, Pritha Bari, Sabino Matarrese +1
Primordial gravitational waves (PGWs) generate scalar density perturbations at second order. Since the induced density contrast is quadratic in the tensor field, it is intrinsicall…
Probing scalar-tensor-induced gravitational waves in the nHz band: NANOGrav and SKA
William Iania, Angelo Ricciardone
Scalar-induced gravitational waves (SIGWs) have recently attracted considerable interest, both as a possible explanation for the nanohertz signal reported by the Pulsar Timing Arra…
Inflation without an Inflaton III: non-Gaussian signatures
Mariam Abdelaziz, Marisol Traforetti, Daniele Bertacca +3
We investigate primordial non-Gaussianity in the Inflation without an Inflaton (IWI) framework, where scalar perturbations are generated at second order by primordial gravitational…
Probing Cosmic Expansion and Early Universe with Einstein Telescope
Angelo Ricciardone, Mairi Sakellariadou, Archisman Ghosh +52
Over the next two decades, gravitational-wave (GW) observations are expected to evolve from a discovery-driven endeavour into a precision tool for astrophysics, cosmology, and fund…
The Sequential Monte Carlo goes NUTS: Boosting Gravitational-Wave Inference
Gabriele Demasi, Giulia Capurri, Massimo Lenti +9
Sequential Monte Carlo (SMC) methods have recently been applied to gravitational-wave inference as a powerful alternative to standard sampling techniques, such as Nested Sampling.…
