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

We present data for single and binary massive stars, both from new analyses (Trapezium stars, O stars in NGC 6611, and the massive binary system V478 Cyg) and collected from the literature. We show that data for single stars depart from the theoretical ZAMS, while those for binary systems are consistent with a ZAMS formed through a linearly mass
