Stellar kinematics for the central spheroid in the Polar Disk Galaxy NGC 4650 A 1
We have obtained high angular resolution, high signal-to-noise spectra of the Calcium triplet absorption lines on the photometric axes of the stellar spheroid in the polar disk galaxy NGC 4650A. Along the major axis, the observed rotation and velocity dispersion measurements show the presence of a kinematically de-coupled nucleus, and a flat velocity dispersion profile. The minor axis kinematic...
متن کاملAnother Flattened Dark Halo: Polar Ring Galaxy A01360801
Knowledge of the shape of dark matter halos is critical to our understanding of galaxy formation, dynamics, and of the nature of dark matter itself. Polar ring galaxies (PRGs) | early-type galaxies deened by their outer rings of gas, dust and stars on orbits nearly perpendicular to those of the central host | provide a rare probe of the vertical-to-radial axis ratio (q = c=a) of dark halos. We ...
متن کاملOn the Nature of the Ring-like Structure in the Outer Galactic Disk
We examine the tidal disruption of satellite galaxies in a cosmological simulation of the formation of a disk galaxy in the ΛCDM scenario. We find that the disruption of satellite galaxies in orbits roughly coplanar with the disk leads naturally to the formation of ring-like stellar structures similar to that recently discovered in the outer disk of the Milky Way. Two interpretations appear pla...
متن کاملSurface Brightness Gradients Produced by the Ring Waves of Star Formation
We compute surface brightness profiles of galactic disks for outwardly propagating waves of star formation with a view to investigate the stellar populations in ring galaxies. We consider two mechanisms which can create outwardly propagating star forming rings in a purely gaseous disk — a self-induced wave and a density wave. We show that the surface brightness profiles produced by both scenari...
متن کاملFormation of a polar-ring galaxy in a galaxy merger
We numerically investigate stellar and gas dynamics in star-forming and dissipative galaxy mergers between two disk galaxies with specific orbital configurations. We find that violent relaxation combined with gaseous dissipation in galaxy merging transforms two disk galaxies into one S0 galaxy with polar-rings: Both the central S0-like host and the polar-ring component in a polar-ring galaxy ar...
