Mapping the Active Galactic Nucleus Effects on the Stellar and Gas Properties of NGC 5806
The Astrophysical JournalIt is commonly accepted that active galactic nuclei (AGNs) have a strong impact upon the evolution of their host galaxies, but the processes by which they do so are not fully understood.

UniverseSimulations of intermediate-mass black holes (IMBHs) in dwarf galaxies within 10 Mpc that host bright nuclear star clusters (NSCs), prime candidates for IMBH formation, using the High Angular Resolution Monolithic Optical and Near-infrared Integral ...

On the Origin of the Variety of Velocity Dispersion Profiles of Galaxies
The Astrophysical JournalObserved and simulated galaxies exhibit a significant variation in their velocity dispersion profiles. We examine the inner and outer slopes of stellar velocity dispersion profiles using integral field spectroscopy data from two surveys, SAMI (for z < 0 ...

Dynamics of the disks of nearby galaxies [PDF]
Astronomische Nachrichten, 2008 AbstractI describe how the dynamics of galactic disks can be inferred by imaging and spectroscopy. Next I demonstrate that the decomposition of the rotation curves of spiral galaxies into the contributions by the various components of the galaxies is highly degenerate.

Dynamical evolution of triplets of galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2001 By means of N-body simulations we study the global dynamics of triplets of galaxies, considering initial conditions starting from `maximum expansion' and in virial equilibrium. Unlike previous studies we treat galaxies self-consistently. We do not consider the influence of a primordial common halo of dark matter.

The Intrinsic Flattening of Galaxy Disks
The Astrophysical JournalHighly inclined (edge-on) disk galaxies offer the unique perspective to constrain their intrinsic flattening, c / a , where c and a are, respectively, the vertical and long radial axes of the disk measured at suitable stellar densities.

, 1999 Our Galaxy is a barred spiral. Recent work based on the COBE NIR data implies a small bulge-bar and a disk with a short scale-length. The corotation radius of the bar is in the range 3-4.5 kpc. The stellar density distribution beyond the end of the bar appears to be perturbed strongly by the Galaxy's spiral arms.
