Searching for axion-like particle decay in the near-infrared background: an updated analysis
Andrea Caputo, Andrea Vittino, Nicolao Fornengo +2
The extragalactic background light is comprised of the cumulative radiation from all galaxies across the history of the universe. The angular power spectrum of the anisotropies of…
Plasma-photon interaction in curved spacetime I: formalism and quasibound states around nonspinning black holes
Enrico Cannizzaro, Andrea Caputo, Laura Sberna +1
We investigate the linear dynamics of an electromagnetic field propagating in curved spacetime in the presence of plasma. The dynamical equations are generically more involved and…
Directional detection of light dark matter from three-phonon events in superfluid He
Andrea Caputo, Angelo Esposito, Fulvio Piccinini +2
We present the analysis of a new signature for light dark matter detection with superfluid He: the emission of three phonons. We show that, in a region of mass below the MeV, t…
Strategies to Detect Dark-Matter Decays with Line-Intensity Mapping
José Luis Bernal, Andrea Caputo, Marc Kamionkowski
The nature of dark matter is a longstanding mystery in cosmology, which can be studied with laboratory or collider experiments, as well as astrophysical and cosmological observatio…
The see-saw portal at future Higgs Factories
Daniele Barducci, Enrico Bertuzzo, Andrea Caputo +2
We consider an extension of the Standard Model with two right-handed singlet fermions with mass at the electroweak scale that induce neutrino masses, plus a generic new physics sec…
Detectable environmental effects in GW190521-like black-hole binaries with LISA
Alexandre Toubiana, Laura Sberna, Andrea Caputo +9
GW190521 is the compact binary with the largest masses observed to date, with at least one in the pair-instability gap. This event has also been claimed to be associated with an op…
