    • Attenuation modified by DIG and dust as seen in M31 
      Tomicic, Neven; Kreckel, Kathryn; Groves, Brent; Schinnerer, Eva; Sandstrom, Karin; Kapala, Maria; Blanc Mendiberri, Guillermo; Leroy, Adam (IOP Publishing Ltd, 2017)
      The spatial distribution of dust in galaxies affects the global attenuation, and hence inferred properties, of galaxies. We trace the spatial distribution of dust in five approximately kiloparsec fields of M31 by comparing ...
    • Dust Emission at 8 and 24 µm as Diagnostics of H II Region Radiative Transfer 
      Oey, M. S.; López Hernández, J.; Kellar, J. A.; Pellegrini, E. W.; Gordon, K. D.; Jameson, K. E.; Li, A.; Madden, S. C.; Meixner, M.; Roman Duval, Julia; Bot, C.; Rubio López, Mónica; Tielens, A. G. G. M. (IOP Publishing Ltd, 2017)
      We use the Spitzer Surveying the Agents of Galaxy Evolution (SAGE) survey of the Magellanic Clouds to evaluate the relationship between the 8 mu m polycyclic aromatic hydrocarbon (PAH) emission, 24 mu m hot dust emission, ...
    • Hot gas around SN 1998bw: inferring the progenitor from its environment 
      Kruehler, T.; Kuncarayakti, H.; Schady, P.; Anderson, J. P.; Galbany, Lluis; Gensior, J. (EDP Sciences, 2017)
      Spatially resolved spectroscopy of the environments of explosive transients carries detailed information about the physical properties of the stellar population that gave rise to the explosion, and thus the progenitor ...
    • Molecular line emission as a tool for galaxy observations (LEGO). I. HCN as a tracer of moderate gas densities ... 
      Kauffmann, Jens; Goldsmith, Paul F.; Melnick, Gary; Tolls, Volker; Guzmán, Andrés; Menten, Karl M. (EDP Sciences, 2017)
      Trends observed in galaxies, such as the Gao & Solomon relation, suggest a linear relationship between the star formation rate and the mass of dense gas available for star formation. Validation of such trends requires the ...
    • The carina nebula and gum 31 molecular complex: II. The distribution of the atomic gas revealed in unprecedented ... 
      Rebolledo, David; Green, Anne J.; Burton, Michael; Brooks, Kate J.; Breen, Shari L.; Gaensler, B. M.; Contreras, Yanett; Braiding, Catherine; Purcell, Cormac (Oxford University Press, 2017)
      We report high spatial resolution observations of the HI 21cm line in the Carina Nebula and the Gum 31 region obtained with the Australia Telescope Compact Array. The observations covered similar to 12 deg(2) centred on l ...
    • The extended law of star formation: the combined role of gas and stars 
      Dib, Sami; Hony, Sacha; Blanc Mendiberri, Guillermo (Oxford University Pres, 2017)
      We present a model for the origin of the extended law of star formation in which the surface density of star formation (Sigma(SFR)) depends not only on the local surface density of the gas (Sigma(g)) but also on the stellar ...
    • VALES I: the molecular gas content in star-forming dusty H-ATLAS galaxies up to z=0.35 
      Villanueva, V.; Ibar, E.; Hughes, T. M.; Lara López, M. A.; Molina, J. (Oxford University Press, 2017)
      We present an extragalactic survey using observations from the Atacama Large Millimeter/ submillimeter Array (ALMA) to characterize galaxy populations up to z = 0.35: the Valparaiso ALMA Line Emission Survey (VALES). We ...
