SUMMARY:Prospects for Supernova Magnetometry with Neutrinos\, Theory S
 eminar (High Energy/Cosmology)\, Garv Chauhan\, Arizona State Universi
 ty
DESCRIPTION:A Galactic supernova neutrino burst could offer a way to i
 nvestigate the magnetic fields of a newly formed neutron star. Electro
 n spin polarization in a strong magnetic field introduces a directiona
 l dependence in neutrino interactions\, potentially producing anisotro
 pic emission from the proto–neutron star. If the magnetic axis is in
 clined to the rotation axis\, this anisotropy can generate a periodic 
 modulation in the neutrino signal observed at Earth. In this talk\, I 
 will discuss the physical origin of this effect and a phenomenological
  framework for estimating its impact on the electron-antineutrino flux
 . I will examine the prospects for detecting such a modulation with Ic
 eCube\, discussing the potential detection reach and whether the modul
 ation’s amplitude and temporal evolution could constrain the magneti
 c-field strength and its evolution near the neutrinosphere. I will als
 o discuss the potential role of complementary neutrino observations wi
 th DUNE\, gravitational-wave measurements\, and future IceCube-Gen2 ca
 pabilities. This approach could open a new avenue for supernova magnet
 ometry\, offering insight into the magnetic fields of newborn neutron 
 stars.
