Astroparticle physics is undergoing a profound transformation, due to a series of extraordinary new results, such as the discovery of high-energy cosmic neutrinos with IceCube, the direct detection of gravitational waves with LIGO and Virgo, and many others. This white paper is the result of a collaborative effort that involved hundreds of theoretical astroparticle physicists and cosmologists, under the coordination of the European Consortium for Astroparticle Theory (EuCAPT). Addressed to the… 

Near-future discovery of the diffuse flux of ultra-high-energy cosmic neutrinos

Ultra-high-energy (UHE) neutrinos, with EeV-scale energies, carry with them unique insight into fundamental open questions in astrophysics and particle physics. For fifty years, they have evaded

CRPropa 3.2 — an advanced framework for high-energy particle propagation in extragalactic and galactic spaces

The landscape of high- and ultra-high-energy astrophysics has changed in the last decade, largely due to the inflow of data collected by large-scale cosmic-ray, gamma-ray, and neutrino observatories.

Astrophysical and Cosmological Probes of Dark Matter

While astrophysical and cosmological probes provide a remarkably precise and consistent picture of the quantity and general properties of dark matter, its fundamental nature remains one of the most

Pulsar timing residual induced by wideband ultralight dark matter with spin 0,1,2

The coherent oscillation of ultralight dark matter in the mass regime around 10 − 23 eV induces changes in gravitational potential with the frequency in the nanohertz range. This effect is known to

Resonant Production of Light Sterile Neutrinos in Compact Binary Merger Remnants

The existence of eV-mass sterile neutrinos is not ruled out because of persistent experimental anomalies. Upcoming multi-messenger detections of neutron-star merger remnants could provide indirect
