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

In this poster we present preliminary results from integral field 3D spectroscopy of the two prototypical star-forming galaxies IZw18 and IIZw70. The observations were taken with the instruments INTEGRAL/WYFFOS at the WHT (ORM, La Palma, Spain) and PMAS at the 3.5m telescope of CAHA (Calar Alto, Almeria, Spain). The observations cover a spectral

We are using integral field spectroscopy (IFS) data together with archival Hubble Space Telescope (HST) images, for carrying out a program aimed at studying a representative sample of local luminous and ultraluminous infrared galaxies (LIRGs and ULIRGs; 11 ≤ log(LIR/L&sun;)≤13). Our goals are to characterize the stellar and ionized gas structure

SPIRE, the Spectral and Photometric Imaging Receiver, is one of three instruments to fly on the European Space Agency’s Herschel Space Observatory. It contains a three-band imaging photometer operating at 250, 350 and 500 μm, and an imaging Fourier transform spectrometer covering 194 672 μm. The SPIRE detectors are arrays of feedhorn-coupled
