Galaxy dynamics with the Planetary Nebula Spectrograph
N. R. Napolitano, A. J. Romanowsky, N. G. Douglas +6
The Planetary Nebula Spectrograph is a dedicated instrument for measuring radial velocity of individual Planetary Nebulae (PNe) in galaxies. This new instrument is providing crucia…
Mass-to-light ratios in early-type galaxies and the dark matter content
M. Capaccioli, N. R. Napolitano, M. Arnaboldi
The distribution of the radial trends of the mass-to-light ratios (M/L) within an assorted sample of early-type galaxies is discussed. Three classes of galaxies are identified acco…
Use of DPOSS data to study globular cluster halos: an application to M 92
V. Testa, S. R. Zaggia, S. Andreon +4
We exploited the large areal coverage offered by the DPOSS to analyze the outermost regions of the galactic globular cluster M 92. Two independent photometric reduction programs (S…
The morphological segregation of galaxies in clusters. III. The distant cluster Cl0939+4713 (Abell 851)
S. Andreon, E. Davoust, T. Heim
We have performed an isophotal analysis of galaxies in the distant (z=0.4) cluster Cl0939+4713 (Abell 851), using post-refurbished Hubble Space Telescope images. Morphological type…
