Dark matter in early – type galaxies : dynamical modelling of IC 1459 , IC 3370 , NGC 3379 and NGC 4105
We analyse long–slit spectra of four early–type galaxies which extend from ∼ 1 to ∼ 3 effective radii: IC 1459, IC 3370, NGC 3379 and NGC 4105. We have extracted the full line–of–sight velocity distribution (in the case of NGC 3379 we also used data from the literature) which we model using the two–integral approach. Using two–integral modelling we find no strong evidence for dark haloes, but t...
متن کاملNuclear stellar discs in low - luminosity elliptical galaxies : NGC 4458 and NGC 4478
We present the detection of nuclear stellar discs in the low-luminosity elliptical galaxies NGC 4458 and NGC 4478, which are known to host a kinematically-decoupled core. Using archival HST imaging, and available absorption line-strength index data based on ground-based spectroscopy, we investigate the photometric parameters and the properties of the stellar populations of these central structu...
متن کاملGlobular Clusters as Tracers of Stellar Bi - modality in Elliptical Galaxies : The Case of NGC 1399
Globular cluster systems (GCS) frequently show a bi-modal distribution of the cluster integrated colours. This work explores the arguments to support the idea that the same feature is shared by the diffuse stellar population of the galaxy they are associated with. The particular case of NGC 1399, one of the dominant central galaxies in the Fornax cluster, for which a new B surface brightness pr...
متن کاملNgc 4261 and Ngc 4697 : Rejuvenated Elliptical Galaxies
Chandra images present evidence for a non-uniform spatial distribution of discrete X-ray sources in the elliptical galaxy NGC 4261. This non-uniform distribution is inconsistent with the optical morphology of NGC 4261 at greater than a 99.9% confidence level. Similar evidence is seen in one more elliptical galaxy (NGC 4697; 98% confidence level) out of five cases we investigated. NGC 4261 and N...
متن کاملDark matter in early - type spiral galaxies : the case of NGC 2179 and of NGC 2775 ⋆ , ⋆ ⋆
We present the stellar and ionized-gas velocity curves and velocity-dispersion profiles along the major axis for six early-type spiral galaxies. Two of these galaxies, namely NGC 2179 and NGC 2775, are particularly suited for the study of dark matter halos. Using their luminosity profiles and modeling their stellar and gaseous kinematics, we derive the mass contributions of the luminous and the...
