Role of Magnetic Fields in Fueling Seyfert Nuclei

Abstract Molecular gas is believed to be the fuel for star formation and nuclear activity in Seyfert galaxies. To explore role of magnetic fields funneling molecular into region, measurements embedded are needed. By applying new velocity gradient technique (VGT) CO isotopolog data from Atacama Large Millimeter/submillimeter Array Plateau de Bure Interferometer Arcsecond Whirlpool Survey, we obtain first detection CO-associated several nearby galaxies their unprecedented high-resolution field maps. The VGT-measured globally agree with those inferred existing HAWC+ dust polarization Very synchrotron polarization. An overall good alignment between traced by VGT-CO may support correlation cosmic-ray generation. We find that have a significant radial component central regions most Seyferts our sample, where efficient inflows or outflow occur. In particular, local misalignment within ring NGC 1097, former aligns bar’s orientation. This reveals different configurations phases provide an observational diagnostic ongoing multiphase fueling activity.
