Abstract:
Seven very luminous galaxies were examined to determine the contribution of active nuclei to their luminosity, the nature of their stellar population, and the validity of previous measurements of their H₂ content. Spectra of the 2.3 μm bands of CO were used to measure the stellar velocity dispersion, and hence the mass in the central regions. The bolometric luminosity, ionizing continuum luminosity, CO index, and 2.2 μm luminosity were also determined. Models of young stellar populations were compared to the observed properties of the galaxies. It was found that four of the seven galaxies have

Abstract:
All classes of Active Galactic Nuclei (AGN) are fundamentally powered by accretion of gas onto a supermassive black hole. The process converts the potential energy of the infalling matter to X-ray and ultraviolet (UV) radiation, releasing up to several 1012 solar luminosities. Observations show that the accreting "central engines" in AGN are surrounded by dusty matter. The dust occupies a "torus" around the AGN which is comprised of discrete clumps. If the AGN radiation is propagating through the torus on its way to an observer, it will be heavily re-processed by the dust, i.e. converted from

Abstract:
<p> Feedback from active galactic nuclei (AGN) is thought to regulate the growth of supermassive black holes (SMBHs) and galaxies. The most direct evidence of AGN feedback is probably galactic outflows. This thesis addresses the link between SMBHs and their host galaxies from four different observational perspectives. First, I study the local correlation between black hole mass and the galactic halo potential (the <i>M</i><i>BH</i> &ndash; <i> V</i><sub>c</sub> relation) based on Very Large Array (VLA) HI observations of galaxy rotation curves. Although there is a correlation, it is no tighter

Abstract:
We present a study into the existence of the broad Fe Ka line, the hot nature of the ionised gas surrounding Active Galactic Nuclei, most commonly referred to as 'warm absorbers', and the AGN environment. We begin with an investigation of the Seyfert 1.5 galaxy NGC 3516. In our analysis, we use the Chandra telescope to explore the environment around the black hole, utilising the high resolution of the spectrometer to constrain the physical parameters. In conjunction with this we use the large effective area of Suzaku in order to detect subtle features such as the broad KO' feature. In this wor

Abstract:
Near-infrared and optical CCD images of radio-loud quasars, radio-quiet quasars and radio galaxies (RLQs, RQQs, and RGs respectively) are presented. The quasar samples are chosen such that they are well matched in the V-z plane, whilst the RGs are selected so that their radio properties (5 GHz radio power and spectral index)are matched to those of the RLQs. The images of all three samples have been analysed using detailed 2-dimensional modelling to extract the parameters of the host galaxies. The low nuclear:host ratios displayed by quasars at 2.2gm combined with the consistent depth of the im
