    • A portrait of cold gas in galaxies at 60 pc resolution and a simple method to test hypotheses that link small-scale ism structure to galaxy-scale processes 

      Leroy, Adam; Hughes, Annie; Schruba, Andreas; Rosolowsky, Erik; Blanc Mendiberri, Guillermo; Bolatto, Alberto; Colombo, Dario; Escala Astorquiza, Andrés; Kramer, Carsten; Diederik Kruijssen, J. M. (The American Astronomical Society, 2016-11-01)
      The cloud-scale density, velocity dispersion, and gravitational boundedness of the interstellar medium (ISM) vary within and among galaxies. In turbulent models, these properties play key roles in the ability of gas to ...

      Leroy, Adam K.; Schinnerer, Eva; Hughes, Annie; Kruijssen, J. M.Diederik; Meidt, Sharon; Schruba, Andreas; Sun, Jiayi; Bigiel, Frank; Aniano, Gonzalo; Blanc, Guillermo A.; Bolatto, Alberto; Chevance, Mélanie; Colombo, Dario; Gallagher, Molly; García Burillo, Santiago; Kramer, Carsten; Querejeta, Miguel; Pety, Jerome; Thompson, Todd A.; Usero, Antonio (Institute of Physics, 2017)
      We compare the structure of molecular gas at 40pc resolution to the ability of gas to form stars across the disk of the spiral galaxy M51. We break the PAWS survey into 370pc and 1.1kpc resolution elements, and within ...

      Aims. We present clumps of dust emission from Herschel observations of the Large Magellanic Cloud (LMC) and their physical and statistical properties. We catalog cloud features seen in the dust emission from Herschel ...
    • Determining dust temperatures and masses in the Herschel era: The importance of observations longward of 200 micron 

      Gordon, K. D.; Galliano, F.; Hony, S.; Bernard, J. P.; Bolatto, Alberto; Bot, Caroline; Engelbracht, C.; Hughes, A.; Israel, F. P.; Kemper, F.; Kim, S.; Li, A.; Madden, S.

      The properties of the dust grains (e.g., temperature and mass) can be derived from fitting far-IR SEDs (≥100 μm). Only with SPIRE on Herschel has it been possible to get high spatial resolution at 200 to 500 μm that is ...
    • Dust/gas correlations from Herschel observations 

      Roman Duval, J.; Israel, F. P.; Bolatto, Alberto; Hughes, A.; Leroy, A.; Meixner, M.; Gordon, K.; Madden, S. C.; Paradis, D.; Kawamura, A.; Li, A.; Sauvage, M.; Wong, T.; Bernard, J. P.; Engelbracht, C.; Hony, S.; Kim, S.; Misselt, K.; Okumura, K.; Ott, Jürgen; Panuzzo, P.; Pineda, J. L.; Reach, W. T.; Rubio López, Mónica (2010)
      12CO rotational emission lines and Hi 21 cm emission. This so-called “FIR excess” is especially noticeable near molecular clouds in the LMC, and has usually been interpreted as indicating the presence of a self-shielded ...
    • HERschel Inventory of The Agents of Galaxy Evolution (HERITAGE): The Large Magellanic Cloud dust 

      Meixner, M.; Galliano, F.; Hony, S.; Roman-Duval, J.; Robitaille, T.; Panuzzo, P.; Sauvage, M.; Gordon, K.; Engelbracht, C.; Misselt, K.; Okumura, K.; Beck, T.; Bernard, J.
