nmagic: a fast parallel implementation of a χ2-made-to-measure algorithm for modelling observational data
TL;DR: In this paper, a made-to-measure (M2M) algorithm for constructing N-particle models of stellar systems from observational data (X 2 M2M), extending earlier ideas by Syer & Tremaine, is described.
Journal ArticleDOI
Dark matter content and internal dynamics of NGC 4697 : NMAGIC particle models from slit data and planetary nebula velocities
Flavio De Lorenzi,Ortwin Gerhard,Roberto P. Saglia,Niranjan Sambhus,Victor P. Debattista,Maurilio Pannella,Roberto H. Méndez +6 more
TL;DR: In this paper, the authors 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 long-slit absorption-line kinematic data, and published planetary nebula (PN) velocity data.
Journal ArticleDOI
Kinematic Evidence for Different Planetary Nebula Populations in the Elliptical Galaxy NGC 4697
TL;DR: In this article, the authors analyzed the magnitudes, kinematics, and positions of a complete sample of 320 planetary nebulae (PNs) in the elliptical galaxy NGC 4697 and identified a subpopulation of PNs that is azimuthally unmixed and kinematically peculiar.
Journal ArticleDOI
Kinematic evidence for different Planetary Nebulae Populations in the elliptical galaxy NGC 4697
TL;DR: In this paper, the authors analyzed the magnitudes, kinematics and positions of a complete sample of 320 planetary nebula points in the elliptical galaxy NGC 4697 and identified a subpopulation of PNs which is azimuthally unmixed and kinematically peculiar, and which neither traces the distribution of all stars nor can it be in dynamical equilibrium with the galaxy potential.
Journal ArticleDOI
Dynamical Modeling of the Stellar Nucleus of M31
Niranjan Sambhus,S. Sridhar +1 more
TL;DR: In this paper, stellar dynamical models of the lopsided double-peaked nucleus of M31, derived from Hubble Space Telescope (HST) photometry, were presented.
