Intracluster stars tracing motions in nearby clusters
Magda Arnaboldi
Cosmological simulations of structure formation predict that galaxies are dramatically modified by galaxy harassment during the assembly of galaxy clusters, losing a substantial fr…
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…
The Planetary Nebulae Spectrograph: the green light for Galaxy Kinematics
N. G. Douglas, M. Arnaboldi, K. C. Freeman +10
Planetary nebulae are now well established as probes of galaxy dynamics and as standard candles in distance determinations. Motivated by the need to improve the efficiency of plane…
NGC 1399: a complex dynamical case
N. R. Napolitano, M. Arnaboldi, M. Capaccioli
Evidence for a disturbed velocity structure in the outer regions of the galaxy NGC1399 comes from a re-analysis of the planetary nebulae data from Arnaboldi et al. (1994). We find…
Extragalactic planetary nebulae as mass tracers: biases in the estimate of dynamical quantities
M. Arnaboldi, N. Napolitano, M. Capaccioli
Planetary Nebulae (PNe) are very important kinematical tracers of the outer regions of early-type galaxies, where the integrated light techniques fail. Under ad hoc assumptions, th…
More evidence for an intracluster planetary nebulae population in the Virgo cluster
R. H. Mendez, M. A. Guerrero, K. C. Freeman +5
We surveyed a 50 sq arcmin region in the Virgo cluster core to search for intergalactic planetary nebulae, and found 11 candidates in the surveyed area. The measured fluxes of thes…
