We discuss how a wide field imager with very high spatial resolution on a relatively small telescope but located in an observing site with very good seeing might constrain the fraction of binary stars in Galactic globular clusters. We also mention the role that the new data might play in investigating advanced evolutionary phases of low-mass stars

The National Center for Atmospheric Research (NCAR) has undertaken a 3-year initiative to develop the Community Spectro-polarimetric Analysis Center (CSAC). The goal of this effort is to provide the community with standardized tools for extracting the solar magnetic field vector and related atmospheric parameters from spectro-polarimetric

We present results from our ongoing effort to understand the morphological and kinematical properties of early-type galaxies using the integral-field spectrograph SAURON. We discuss the relation between the stellar and gas morphology and kinematics in our sub-sample of 24 representative Sa spiral bulges. We focus on the frequency of kinematically

Dark Matter supposedly dominates the extragalactic Universe (Peebles 1993; Peacock 1998; Moore et al. 1999; D’Onghi & Lake 2004), yet no dark structure of galactic proportions has ever been convincingly identified. Earlier (Minchin et al. 2005) we suggested that VIRGOHI 21, a 21-cm source we found in the Virgo Cluster at Jodrell Bank using single

The SAURON integral field spectrograph was used to observe the central parts of the galaxy M100. We present here maps of Hβ emission and gas velocity dispersion. We focus on the discovery of a cold (low velocity dispersion) ring of gas, coinciding spatially with enhanced massive star formation as indicated here by Hβ emission and outlining the well
