Indirect searches for signatures of corpuscular dark matter have been
performed using all cosmic messengers: gamma rays, cosmic rays, and neutrinos.
The search for dark matter from neutrinos is of particular importance since
they are the only courier that can reach detectors from dark matter processes
in dense environments, such as the core of the Sun or Earth, or from the edge
of the observable Universe. In this work, we introduce $chi$aro$nu$, a
software package that, in the spirit of its mythological Greek namesake $chi
acutealpha rho omega nu $, bridges the dark sector and Standard Model by
predicting neutrino fluxes from different celestial dark matter agglomerations.
The flux at the point of production is either computed internally by
$chi$aro$nu$ or is taken from user supplied tables. $chi$aro$nu$ then
propagates this flux through vacuum or dense media and returns the expected
neutrino yield at an observer’s location. In developing $chi$aro$nu$, we have
revisited and updated the production of neutrinos in dense media, updated the
propagation of high-energy neutrinos, and studied the sources of uncertainty in
neutrino transport. This package is coupled to a new calculation that includes
electroweak corrections resulting in the most up-to-date and complete
repository of neutrino fluxes from dark matter decay and annihilation over the
energy range of 1 GeV to 10 PeV coming from the Earth, the Sun, and the
Galactic halo.
