Candidates for Intracluster Planetary Nebulae in the Virgo Cluster based on the Suprime-Cam Narrow-Band Imaging in O[III] and Halpha
S. Okamura, N. Yasuda, M. Arnaboldi +17
We have identified 38 candidates of intracluster planetary nebulae (ICPNe) in a field in the core of the Virgo cluster based on the Suprime-Cam imaging through two n…
Narrow band imaging in [OIII] and Halpha to search for ICPNe in the Virgo cluster
M. Arnaboldi, K. C. Freeman, S. Okamura +17
We have identified intracluster planetary nebulae in a Virgo cluster core field by imaging with the Subaru Suprime-Cam through two narrow band filters centered at the redshifted wa…
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…
Data reduction and astrometry strategies for wide-field images: an application to the Capodimonte Deep Field
J. M. Alcala', M. Radovich, R. Silvotti +4
The Capodimonte Deep Field (OACDF) is a multi-colour imaging survey on two 0.5x0.5 square degree fields performed in the BVRI bands and in six medium-band filters (700 - 900 nm) wi…
