BeppoSAX observation of the rich cluster of galaxies Abell 85
G. B. Lima Neto, V. Pislar, J. Bagchi
We report the observation of the Intra-Cluster Medium (ICM) of Abell 85 by the X-ray satellite BeppoSAX. We have both analysed the spectrum obtained in the central 8 arcmin circula…
The Cluster of Galaxies Abell 970
L. Sodre, D. Proust, H. V. Capelato +4
We present a dynamical analysis of the galaxy cluster Abell 970 based on a new set of radial velocities measured at ESO, Pic du Midi and Haute-Provence observatories. Our analysis…
The specific entropy of elliptical galaxies: an explanation for profile-shape distance indicators?
Gastao B. Lima Neto, Daniel Gerbal, Isabel Marquez
Dynamical systems in equilibrium have a stationary entropy; we suggest that elliptical galaxies, as stellar systems in a stage of quasi-equilibrium, may have a unique specific entr…
The diffuse, relic radio source in Abell 85: estimation of cluster scale magnetic field from inverse Compton X-rays
J. Bagchi, V. Pislar, G. B. Lima Neto
We report the first detection of an inverse Compton X-ray emission, spatially correlated with a very steep spectrum radio source (VSSRS), 0038-096, without any detected optical cou…
The entropy of elliptical galaxies in Coma: a clue for a distance indicator
Daniel Gerbal, Gastao B. Lima Neto, Isabel Marquez +1
We have fitted the surface brightness of a sample of 79 elliptical galaxies pertaining to the Coma cluster of galaxies using the Sersic profile. This model is defined through three…
