Nanohertz gravitational waves from the baryon-dark matter coincidence
Alessia Musumeci, Jacopo Nava, Silvia Pascoli +1
The nanohertz gravitational waves (GW) observed by pulsar timing arrays may originate from a cosmological first-order phase transition (PT) at 100 MeV. Taking this possibili…
Diffuse astrophysical neutrinos from dark matter around blazars
Andrea Giovanni De Marchi, Alessandro Granelli, Jacopo Nava +1
Neutrinos from blazars can originate from inelastic scatterings between protons within their jets and sub-GeV dark matter (DM) around them, explaining IceCube detections of neutrin…
Boosted dark matter versus dark matter-induced neutrinos from single and stacked blazars
Andrea Giovanni De Marchi, Alessandro Granelli, Jacopo Nava +1
The physics responsible for the production of observed high-energy neutrinos have not been established so far, neither for the diffuse astrophysical ones nor for those detected fro…
Did IceCube discover Dark Matter around Blazars?
Andrea Giovanni De Marchi, Alessandro Granelli, Jacopo Nava +1
Models of blazar jets, that explain observations of their photon spectra, typically predict too few neutrinos to be possibly seen by existing telescopes. In particular, they fall s…
From oversimplified to overlooked: the case for exploring Rich Dark Sectors
Asli Abdullahi, Francesco Costa, Andrea Giovanni De Marchi +9
The Standard Model (SM) of particle physics provides a very successful description of fundamental particles and their interactions but it is incomplete, as neutrino masses, dark ma…
New Constraints on Axion-Like Particles with the NEON Detector at a Nuclear Reactor
Byung Ju Park, Jae Jin Choi, Eunju Jeon +17
We report new constraints on axion-like particles (ALPs) using data from the NEON experiment, which features a 16.7 kg of NaI(Tl) target located 23.7 meters from a 2.8 GW thermal p…
