We present Hubble Space Telescope Advanced Camera for Surveys (ACS) observations of 10 galaxies that host narrow-line Seyfert 1 (NLS1) nuclei, believed to contain relatively smaller mass black holes accreting at high Eddington ratios. We deconvolve each ACS image into a nuclear point source (AGN), a bulge, and a disk, and fitted the bulge with a Sersic profile and the disk with an exponential profile. We find that at least five galaxies can be classified as having pseudobulges. All 10 galaxies…

Supermassive black holes in disc-dominated galaxies outgrow their bulges and co-evolve with their host galaxies
The deep connection between galaxies and their supermassive black holes is central to modern astrophysics and cosmology. The observed correlation between galaxy and black hole mass is usually
Galaxy Zoo: bulgeless galaxies with growing black holes
The growth of supermassive black holes appears to be driven by galaxy mergers, violent merger-free processes and/or ‘secular’ processes. In order to quantify the effects of secular evolution on black
Black hole starvation and bulge evolution in a Milky Way-like galaxy
We present a new zoom-in hydrodynamical simulation, `ErisBH', which features the same initial conditions, resolution, and sub-grid physics as the close Milky Way-analogue `Eris' (Guedes et al. 2011),
On the BH-galaxy relation of AGN and Narrow Line Seyfert 1 Galaxies
Massive black holes (BHs) are detected in the centers of many nearby galaxies are linearly correlated with the luminosity of the host bulge (spheroid), the black hole mass being about 0.1% of the
The radio-loud narrow-line Seyfert 1 galaxy 1H 0323+342 in a galaxy merger
The supermassive black holes (SMBHs) of narrow-line Seyfert 1 galaxies (NLS1s) are at the lower end of the mass function of active galactic nuclei (AGNs) and reside preferentially in late-type host
Spiral galaxies as progenitors of pseudo-bulge hosting S0s
We present observations of pseudobulges in S0 and spiral galaxies using imaging data taken with the Spitzer Infra-Red Array Camera. We have used 2-d bulge-disk-bar decomposition to determine
Correlations between Supermassive Black Holes and their Hosts in Active Galaxies
In the last decades several correlations between the mass of the central supermassive black hole (BH) and properties of the host galaxy - such as bulge luminosity and mass, central stellar velocity
Properties of the narrow line Seyfert 1 galaxies revisited
There is growing evidence to suggest that the black hole mass has been previously underestimated with the H$\beta$ line width for certain active galactic nuclei (AGN). With the assumption of the
The overmassive black hole in NGC 1277: new constraints from molecular gas kinematics
We report the detection of CO(1-0) emission from NGC 1277, a lenticular galaxy in the Perseus Cluster. NGC 1277 has previously been proposed to host an overmassive black hole (BH) compared to the
The New Numerical Galaxy Catalogue (ν2GC): properties of active galactic nuclei and their host galaxies
We present the latest results of a semi-analytic model of galaxy formation, "New Numerical Galaxy Catalogue", which is combined with large cosmological N-body simulations. This model can reproduce


Black Holes in Pseudobulges and Spheroidals: A Change in the Black Hole-Bulge Scaling Relations at Low Mass*
We investigate the relationship between black hole mass and host galaxy properties for active galaxies with the lowest black hole masses currently known in galaxy nuclei. HST imaging confirms that
The Growth of Black Holes: Insights from Obscured Active Galaxies
Obscured or narrow-line active galaxies offer an unobstructed view of the quasar environment in the presence of a luminous and vigorously accreting black hole (BH). We exploit the large new sample of
The role of secular evolution in the black hole growth of narrow-line Seyfert 1 galaxies
Narrow-line Seyfert 1 (NLS1) galaxies show extreme properties with respect to the other Seyfert galaxies. Indeed, they are thought to be accreting at Eddington rates and to possess low-mass black
Black Holes of Active and Quiescent Galaxies. I. The Black Hole-Bulge Relation Revisited
Massive black holes detected in the centers of many nearby galaxies show an approximately linear relation with the luminosity of the host bulge, implying that the black hole (BH) mass is 0.001-0.002
On the black hole–bulge mass relation in active and inactive galaxies
New black hole mass estimates are presented for a sample of 72 active galactic nuclei (AGNs) covering three decades in optical luminosity. Using a subsample of Seyfert galaxies, which have black hole
The growth of supermassive black holes in pseudo-bulges, classical bulges and elliptical galaxies
Using results from structural analysis of a sample of nearly 1000 local galaxies from the Sloan Digital Sky Survey, we estimate how the mass in central black holes is distributed amongst elliptical
High-redshift galaxies, their active nuclei and central black holes
We demonstrate that the luminosity function of the recently detected population of actively star-forming galaxies at redshift z = 3 and the B-band luminosity function of quasi-stellar objects (QSOs)
Active Galactic Nucleus Black Hole Masses and Bolometric Luminosities
Black hole mass, along with mass accretion rate, is a fundamental property of active galactic nuclei (AGNs). Black hole mass sets an approximate upper limit to AGN energetics via the Eddington limit.
Black hole growth by accretion
We show that black holes grow substantially by accretion at close to Eddington rates. Using a complete sample of soft X-ray selected AGNs, Grupe & Mathur (2004, ApJ, 606, L41) have shown that narrow
