    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 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 State-of-Play of Anomalous Microwave Emission (AME) research
    Anomalous Microwave Emission (AME) is a component of diffuse Galactic radiation observed at frequencies in the range ≈ 10-60 GHz. AME was first detected in 1996...

    The Zn^+^/Na^0^ interstellar ratio
    We study the behaviour of the interstellar R_n_=n(Zn^+^)/n(Na^0^) ratio in ionization equilibrium conditions. The ratio is very sensitive to variations of the...

    Turbulent Gas in Lensed Planck-selected Starbursts at z ∼ 1-3.5
    Dusty star-forming galaxies at high redshift (1 < z < 3) represent the most intense star-forming regions in the universe. Key aspects to these processes are the...
