Diffuse axion-like particle searches
Hendrik Vogel, Ranjan Laha, Manuel Meyer
We propose a new method to search for axion-like particles (ALPs) based on the gamma-rays produced concomitant with high-energy astrophysical neutrinos. The existence of high-energ…
Lepton asymmetry from mixing and oscillations
Alexander Kartavtsev, Peter Millington, Hendrik Vogel
We show how the two physically-distinct sources of CP-asymmetry relevant to scenarios of leptogenesis: (i) resonant mixing and (ii) oscillations between different flavours can be u…
Dark Radiation from a hidden U(1)
Hendrik Vogel, Javier Redondo
We discuss the impact of a hidden sector consisting of Minicharged Particles (MCPs) and massless hidden photons on the expansion history of our Universe. We present parameter scans…
Neutrino propagation in media: Flavor-, helicity-, and pair correlations
A. Kartavtsev, G. Raffelt, H. Vogel
Neutrinos propagating in media (matter and electromagnetic fields) undergo flavor and helicity oscillations, where helicity transitions are instigated both by electromagnetic field…
Dark Radiation constraints on minicharged particles in models with a hidden photon
Hendrik Vogel, Javier Redondo
We compute the thermalization of a hidden sector consisting of minicharged fermions (MCPs) and massless hidden photons in the early Universe. The precise measurement of the anisotr…
