Multimessenger Studies of Seyfert Galaxies

Seyfert galaxies are promising candidates for the production of high-energy neutrinos, building on recent IceCube evidence backing this idea we assemble a Seyfert catalog from multi-wavelength surveys, including Swift-BAT (hard X-ray), VLASS (radio), and Fermi-LAT (γ-ray), among others. We characterize known candidate sources (NGC 1068, NGC 4151, NGC 3079, CGCG 420-015) and derive selection criteria based on redshift, X-ray and radio luminosities, black-hole mass, and related properties to identify more sources with similar emission signatures. We show preliminary γ-ray spectral energy distribution (SED) analyses of our catalog sources, which will support our future studies on the origin of high-energy neutrino production. As the next step, we look to search for neutrino emissions using IceCube data on the sources in the catalog.
