    Quantifying the ionising flux escaping from the ultra-luminous HII regions in four spiral galaxies
    There are two principal problems in explaining, in terms of the emission from OB stars, the ionisation of the gas which emits the diffuse H-alpha in spiral...

    Spatially Resolved Spectroscopy of Wolf-Rayet Ring Nebulae - Part Four - the Fundamental Parameters of the Central Stars
    We derive effective temperatures, luminosities and related parameters for a sample of eight Wolf-Rayet stars - seven WN stars and a WO star - by computing...

    Spatially resolved spectroscopy of WR ring nebulae. I - NGC 2359 and RCW 78
    We report detailed spatially resolved spectroscopy of the WR nebulae NGC 2359 and RCW 78 surrounding the WN 5 HD 56925 and WN 8 HD 117688 stars. The aim of this...

    The Accretion Mode in Sub-Eddington Supermassive Black Holes: Getting into the Central Parsecs of Andromeda
    The inner kiloparsec regions surrounding sub-Eddington (luminosity less than 10 -3 in Eddington units, L Edd) supermassive black holes (BHs) often show a...

    The Fate of the Interstellar Medium in Early-type Galaxies. V. Active Galactic Nucleus Feedback from Optical Spectral Classification
    Quenching of star formation plays a fundamental role in galaxy evolution. This process occurs due to the removal of the cold interstellar medium (ISM) or...

    The growth of the outflows from evolved stars: A live poster
    We present our long-term monitoring, using both ground-based telescopes and the HST, of the expansion in the plane of the sky of the outflows from evolved stars...

    The Interstellar 12CH+/13CH+ Ratio Towards the Scorpius OB1 Association
    We observed the λ 4232 Å CH+ interstellar line in the direction of the Sco OB 1 association (d ≃ 2 kpc) with the aim of detecting variations of the 12C/13C...

    The ionized gas in the spiral galaxy NGC 3359. II. Kinematics
    The spiral galaxy NGC 3359 has been observed in the Hα line with the TAURUS II Fabry-Perot interferometer at the William Herschel Telescope within the BARS...
