Wide-Field CCD Photometry of the Globular Cluster M30
Eric L. Sandquist, Michael Bolte, G. E. Langer +2
We present new VI photometry for the halo globular cluster M30 (NGC 7099), and compute luminosity functions (LFs) in both bands for samples of about 15,000 hydrogen-burning stars f…
A NIR search for high-redshift clusters
C. Mendes de Oliveira, U. Hopp, R. Bender +2
We describe our preliminary results on a search for high-redshift ( 0.5) galaxy clusters using near-infrared photometry obtained with the Omega camera at the 3.5m telescope at…
The kinematics of the warm gas in Hickson compact group of galaxies HCG 90
H. Plana, Cl. Mendes de Oliveira, P. Amram +1
We present kinematic observations of H emission for two early-type galaxies and one disk system, members of the Hickson compact group 90 (HCG 90) obtained with a scanning Fabry-…
Extented ionized gas emission and kinematics of the compact group galaxies in HCG 16: Signatures of mergers
Claudia Mendes de Oliveira, Henri Plana, Philippe Amram +2
We report on kinematic observations of Ha emission line from four late-type galaxies of Hickson Compact Group 16 (H16a,b,c and d) obtained with a scanning Fabry-Perot interferomete…
