Axion-neutrino interactions in seesaw models and astrophysical probes
P. Kivokurtseva
We study axion-neutrino interactions in neutrino-mass extensions of the Standard Model, focusing on the Type-I and inverse seesaw. In these frameworks the effective coupling $g_{aν…

Neutrino production in the central dark-matter spikes of active galaxies
Polina Kivokurtseva
Recent multi-messenger observations suggest that high-energy neutrinos may be produced close to central black holes in active galaxies. These regions may host dark-matter (DM) spik…
