Morphology and Nuclear Spectrum of Seyfert 1 Galaxy: Markarian 110

Markarian 110 (Mrk 110) is a known Seyfert 1 galaxy with unusual tidal features and hosts an Active Galactic Nuclei (AGN) that is considered “x-ray loud” and “radio weak”. By building a morphological and spectral profile of this galaxy we can discern critical features that will assist in the analysis of this galaxy’s AGN using Integral Field Spectroscopy (IFS), more specifically, understanding the mechanisms that drive feeding and feedback with respect to the coevolution of the AGN and the host galaxy itself. Extracting the spectrum from the central 0.35” of the nucleus, it has distinct AGN broad-line emissions for Br δ, Br γ, He I, & Si VI. The velocities in the central 0.35” of the AGN range from ~ 17 – 300 km/s. Applying Galfit to the Hubble Space Telescope (HST) data and modeling the AGN using a Sérsic model; the lack of residuals show that the AGN is the dominant object in the galaxy and outshines its host galaxy. We also confirmed the suspicions of Hutchings & Craven (1988) that the extended linear feature is a tidal tail and not an optical jet by performing a multiwavelength analysis of the galaxy which revealed the properties of a tidal tail, suggesting that Mrk 110 is a merger remnant.
