EPIC-KITCHENS-100 Unsupervised Domain Adaptation Challenge: Mixed Sequences Prediction
Amirshayan Nasirimajd, Simone Alberto Peirone, Chiara Plizzari +1
This report presents the technical details of our approach for the EPIC-Kitchens-100 Unsupervised Domain Adaptation (UDA) Challenge in Action Recognition. Our approach is based on…
Imprints of cosmological tensions in reconstructed gravity
Levon Pogosian, Marco Raveri, Kazuya Koyama +6
There has been a significant interest in modifications of the standard Cold Dark Matter (CDM) cosmological model prompted by tensions between certain datasets, most notably…
Modified Gravity and Cosmology: An Update by the CANTATA Network
Emmanuel N. Saridakis, Ruth Lazkoz, Vincenzo Salzano +50
General Relativity and the CDM framework are currently the standard lore and constitute the concordance paradigm. Nevertheless, long-standing open theoretical issues, as well as…
Latest evidence for a late time vacuum -- geodesic CDM interaction
Natalie B. Hogg, Marco Bruni, Robert Crittenden +2
We perform a reconstruction of the coupling function between vacuum energy and geodesic cold dark matter using the latest observational data. We bin the interaction in seventeen re…
Phenomenology of the generalized cubic covariant Galileon model and cosmological bounds
Noemi Frusciante, Simone Peirone, Luis Atayde +1
We investigate the generalized cubic covariant Galileon model, a kinetically driven dark energy model within the Horndeski class of theories. The model extends the cubic covariant…
Strong Lensing Time Delay Constraints on Dark Energy: a Forecast
Banafshe Shiralilou, Matteo Martinelli, Georgios Papadomanolakis +3
Measurements of time delays between multiple quasar images produced by strong lensing are reaching a sensitivity that makes them a promising cosmological probe. Future surveys will…
Cosmological constraints and phenomenology of a beyond-Horndeski model
Simone Peirone, Giampaolo Benevento, Noemi Frusciante +1
We study observational constraints on a specific dark energy model in the framework of Gleyzes-Langlois-Piazza-Vernizzi theories, which extends the Galileon ghost condensate (GGC)…
Cosmological data favor Galileon ghost condensate over CDM
Simone Peirone, Giampaolo Benevento, Noemi Frusciante +1
We place observational constraints on the Galileon ghost condensate model, a dark energy proposal in cubic-order Horndeski theories consistent with the gravitational-wave event GW1…
Constraints on the interacting vacuum -- geodesic CDM scenario
Matteo Martinelli, Natalie B. Hogg, Simone Peirone +2
We investigate an interacting dark sector scenario in which the vacuum energy is free to interact with cold dark matter (CDM), which itself is assumed to cluster under the sole act…
The road ahead of Horndeski: cosmology of surviving scalar-tensor theories
Noemi Frusciante, Simone Peirone, Santiago Casas +1
In the context of the effective field theory of dark energy (EFT) we perform agnostic explorations of Horndeski gravity. We choose two parametrizations for the free EFT functions,…
The role of the tachyonic instability in Horndeski gravity
Noemi Frusciante, Georgios Papadomanolakis, Simone Peirone +1
The tachyonic instability is associated with the unboundedness of the Hamiltonian from below and results in an unstable low- regime. In the cosmological exploration of modified…
Phenomenology of Large Scale Structure in scalar-tensor theories: joint prior covariance of , and in Horndeski
Juan Espejo, Simone Peirone, Marco Raveri +3
Ongoing and upcoming cosmological surveys will significantly improve our ability to probe the equation of state of dark energy, , and the phenomenology of Large Scale S…
Large-scale structure phenomenology of viable Horndeski theories
Simone Peirone, Kazuya Koyama, Levon Pogosian +2
Phenomenological functions and , also known as and , are commonly used to parameterize modifications of the growth of large-scale structu…
Do current cosmological observations rule out all Covariant Galileons?
Simone Peirone, Noemi Frusciante, Bin Hu +2
We revisit the cosmology of Covariant Galileon gravity in view of the most recent cosmological data sets, including weak lensing. As a higher derivative theory, Covariant Galileon…
A comparison of Einstein-Boltzmann solvers for testing General Relativity
E. Bellini, A. Barreira, N. Frusciante +24
We compare Einstein-Boltzmann solvers that include modifications to General Relativity and find that, for a wide range of models and parameters, they agree to a high level of preci…
Impact of theoretical priors in cosmological analyses: the case of single field quintessence
Simone Peirone, Matteo Martinelli, Marco Raveri +1
We investigate the impact of general conditions of theoretical stability and cosmological viability on dynamical dark energy models. As a powerful example, we study whether minimal…
Constraining f(R) Gravity with Planck Sunyaev-Zel'dovich Clusters
Simone Peirone, Marco Raveri, Matteo Viel +2
Clusters of galaxies have the potential of providing powerful constraints on possible deviations from General Relativity. We use the catalogue of Sunyaev-Zel'dovich sources detecte…
Entangling macroscopic diamonds at room temperature: Bounds on the continuous-spontaneous-localization parameters
S. Belli, R. Bonsignori, G. D'Auria +5
A recent experiment [K. C. Lee et al., Science 334, 1253 (2011)] succeeded in detecting entanglement between two macroscopic specks of diamonds, separated by a macroscopic distance…
