The chemical content of nearby galaxies from planetary nebulae : NGC 147 ⋆
We report the results of spectroscopic observations, obtained with the GEMINI MultiObject Spectrograph, of 8 planetary nebulae (PNe) in the dwarf spheroidal (dSph) galaxy NGC 147, a companion of M 31. The physico-chemical properties of the six brightest PNe (Corradi et. al. 2005) were derived using both the empirical icf method and photoionization modelling with cloudy. Different aspects of the...
متن کاملHRI observations of the Local Group galaxies IC 10 , NGC 147 and NGC 185
We report on pointed X-ray observations of IC 10, NGC 147 and NGC 185 made with the ROSAT High Resolution Imager (HRI). These are three Local Group galaxies that have never been previously studied in detail in the X-ray regime. IC 10 is the closest starburst galaxy to our own Galaxy, and NGC 147 and NGC 185 are companions to M31. We have discovered a variable X-ray source coincident with IC 10....
متن کاملGlobular cluster content and evolutionary history of NGC 147
Context. Globular clusters are representative of the oldest stellar populations. It is thus essential to have a complete census of these systems in dwarf galaxies, from which more massive galaxies are progressively formed in the hierarchical scenario. Aims. We present the results of spectroscopic observations of eight globular cluster candidates in NGC 147, a satellite dwarf elliptical galaxy o...
متن کاملOn the Iron content in rich nearby Clusters of Galaxies
In this paper we study the iron content of a sample of 22 nearby hot clusters observed with BeppoSAX. We find that the global iron mass of clusters is tightly related to the cluster luminosity and that the relatively loose correlation between the iron mass and the cluster temperature follows from the combination of the iron mass vs. luminosity and luminosity vs. temperature correlations. The ir...
