Isolated Star Formation: A Compact HII Region in the Virgo Cluster
Ortwin Gerhard, Magda Arnaboldi, Kenneth C. Freeman +1
We report on the discovery of an isolated, compact HII region in the Virgo cluster. The object is located in the diffuse outer halo of NGC 4388, or could possibly be in intracluste…
2dF Spectroscopy of M104 Globular Clusters
Terry Bridges, Ken Freeman, Katherine Rhode +1
We present preliminary results of 2dF spectroscopy of globular clusters in The Sombrero (M104). We find 56 new clusters, and compile a total sample of 103 velocities combined with…
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…
The Large Scale Distribution of Neutral Hydrogen in the Fornax Region
Meryl Waugh, M. J. Drinkwater, R. L. Webster +22
Using HIPASS data, we have searched for HI in a ~25x25 sq.deg. region centred on the Fornax cluster. Within a velocity search range of 300 - 3700 km/s and a lower flux limit of ~40…
Modern Techniques in Galaxy Kinematics: CDI and the Planetary Nebula Spectrograph
N. G. Douglas, K. Kuijken, A. J. Romanowsky +4
We report here the successful commissioning of the PN.Spectrograph, the first special-purpose instrument for the measurement of galaxy kinematics through the PN population
MACHO Project Analysis of the Galactic Bulge Microlensing Events with Clump Giants as Sources
P. Popowski, T. Vandehei, K. Griest +19
We present preliminary results of the analysis of 5 years of MACHO data on the Galactic bulge microlensing events with clump giants as sources. This class of events allows one to o…
