Neutrino oscillations in the presence of strong gravitational fields a
re studied. We look at very high energy neutrinos (similar to 1 TeV) e
manating from active galactic nuclei (AGN). It is observed that spin f
lavor resonant transitions of such neutrinos may occur in the vicinity
of AGN due to gravitational effects and due to the presence of a larg
e magnetic field (similar to 1 T). A point to note is that matter effe
cts (normal MSW transitions) become negligible in comparison to gravit
ational effects in our scenario.
