We present a comparative study of active galactic nuclei (AGN) between galaxy pairs and isolated galaxies with the final data release MaNGA integral field spectroscopic survey. build sample 391 kinematic within footprint survey select AGN using survey's spectra. use comoving volume densities samples to quantify effects that tidal interactions have on triggering nuclear accretion. Our hypothesis...

We investigate the effect of embedded active galactic nuclei (AGN) in galaxy mergers on the CO molecular line emission by combining non-local thermodynamic equilibrium (LTE) radiative transfer calculations with hydrodynamic simulations. We find that AGN feedback energy in gas rich galaxy mergers can contribute to large molecular outflows which may be detectable via velocityintegrated emission c...

The flux of neutrinos and photons originating from cosmic ray interactions with the interstellar medium in the galaxy is calculated based on current models for high energy particle interactions. The contribution from a possible dark matter halo of the galaxy is considered. The photon flux gets a non-trivial attenuation due to interactions with the cosmic background radiation. The neutrino fluxe...
