Dark matter content and internal dynamics of NGC 4697: NMAGIC particle models from slit data and planetary nebulae velocities
Flavio De Lorenzi, Ortwin Gerhard, Roberto P. Saglia +4
We present a dynamical study of NGC 4697, an almost edge-on, intermediate-luminosity, E4 elliptical galaxy, combining new surface brightness photometry, new as well as published lo…
Kinematic evidence for different Planetary Nebulae Populations in the elliptical galaxy NGC 4697
Niranjan Sambhus, Ortwin Gerhard, Roberto H. Mendez
We have analysed the magnitudes, kinematics and positions of a complete sample of 320 PNs in the elliptical galaxy NGC 4697. We show (i) that the PNs in NGC 4697 do not constitute…
Recovery of transverse velocities of steadily rotating patterns in flat galaxies
S. Sridhar, Niranjan Sambhus
The transverse velocities of steadily rotating, non--axisymmetric patterns in flat galaxies may be determined by a purely kinematical method, using two dimensional maps of a tracer…
Dynamical Modeling of the Stellar Nucleus of M31
Niranjan Sambhus, S. Sridhar
We present stellar dynamical models of the lopsided, double-peaked nucleus of M31, derived from Hubble Space Telescope (HST) photometry. A Schwarzscild-type method, in conjunction…
Stellar orbits in triaxial clusters around black holes in galactic nuclei
Niranjan Sambhus, S. Sridhar
We investigate the orbital structure of a model triaxial star cluster, centered around a supermassive black hole (BH), appropriate to galactic nuclei. Sridhar and Touma (1999) prov…
