Star count ratios in the Galactic globular cluster M92.
We present both space (ACS@HST: F814W, F606W, F475W) and ground-based (MEGACAM@CFHT: u*, g',i',r',z') photometry of the Galactic Globular Cluster (GGC) M92...
We analyze the data from narrow band H-alpha and forbidden O III CCD imaging of a sample of nearby spiral galaxies with active nuclei. The results show that the...
Star Formation and Environment in Compact Groups of Galaxies
H &alpha luminosities are presented in order to study the Star Formation Rates (SFRs) of a sample of galaxies in compact groups from Hickson's (1982) catalogue...
