14329A: an Extreme Seyfert Galaxy
The Astrophysical Journal, 1973 The southern spiral I4329A is found to be the most extreme Seyfert yet discovered. H alpha is 13,000 km s/sup -1/ wide, and f(H BETA ) is 7 x 10/sup 42/ ergs s/sup -1/, which approaches that from the QSOs even if they are at cosmological distances.

Dissecting the γ-Ray Emissions of the Nearby Galaxies NGC 1068 and NGC 253
The Astrophysical JournalIntrigued by recent high-energy study results for nearby galaxies with γ -ray emission and in particular NGC 1068 that has been detected as a neutrino-emitting source by the IceCube Neutrino Observatory, we conduct a detailed analysis of the γ -ray data ...
