Earth rotation turns event timing into a geometric probe of UHE neutrino origin
Andrew Cheek, João Paulo Pinheiro, Jordi Salvado
It has been proposed that the ultra-high-energy (UHE) event detected by KM3NeT could be explained by dark matter (DM) decay. Prima facie this seems unlikely becau…

Seafloor Topography Enhances KM3NeT Sensitivity to ANITA-like Events
Carlos A. Argüelles, Toni Bertólez-MartÃnez, Alba Burgos-Mondéjar +3
In this article, we introduce the concept of \textit{topographic enhancement} in the context of ultra-high-energy neutrino detection by underwater neutrino telescopes. We demonstra…

BBN bounds on neutrinophilic ultralight Dark Matter
Toni Bertólez-MartÃnez, Justo López-Sarrión, Jordi Salvado
The high densities in the early Universe provide a unique laboratory to constrain couplings between feebly interacting particles, such as dark matter and neutrinos. In this article…
