    • A Model for the Onset of Self-gravitation and Star Formation in Molecular Gas Governed by Galactic Forces. ... 
      Meidt, Sharon; Leroy, Adam; Rosolowsky, Erik; Diederik, Kruijssen, J.; Schinnerer, Eva; Schruba, Andreas; Pety, Jerome; Blanc Mendiberri, Guillermo; Bigiel, Frank; Chevance, Melanie; Hughes, Annie; Querejeta, Miguel; Usero, Antonio (Institute of Physics Publishing, 2018)
      Modern extragalactic molecular gas surveys now reach the scales of star-forming giant molecular clouds (GMCs; 20–50 pc). Systematic variations in GMC properties with galaxy environment imply that clouds are not ...
    • A model for the onset of self-gravitation and star formation in molecular gas governed by galactic forces. ... 
      Meidt, Sharon; Glover, Simon C.O.; Diederik Kruijssen, J. M.; Leroy, Adam K.; Rosolowsky, Erik; Schruba, Andreas; Hughes, Annie; Schinnerer, Eva; Usero, Antonio; Bigiel, Frank; Blanc, Guillermo; Chevance, Mélanie; Pety, Jerome; Querejeta, Miguel; Utomo, Dyas (IOP Publishing, 2020)
      In Meidt et al., we showed that gas kinematics on the scale of individual molecular clouds are not entirely dominated by self-gravity but also track a component that originates with orbital motion in the potential of the ...
    • A portrait of cold gas in galaxies at 60 pc resolution and a simple method to test hypotheses that link ... 
      Leroy, Adam K.; Hughes, Annie; Schruba, Andreas; Rosolowsky, Erik; Blanc Mendiberri, Guillermo; Bolatto, Alberto D.; Colombo, Darío; Escala Astorquiza, Andrés; Kramer, Carsten; Diederik Kruijssen, J. M.; Meidt, Sharon; Pety, Jerome; Querejeta, Miguel; Sandstrom, Karin; Schinnerer, Eva; Sliwa, Kazimierz; Usero, Antonio (IOP Publishing, 2016)
      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 ...
    • Dynamical equilibrium in the molecular ISM in 28 nearby star-forming galaxies 
      Sun, Jiayi; Leroy, Adam K.; Ostriker, Eve; Hughes, Annie; Rosolowsky, Erik; Schruba, Andreas; Schinnerer, Eva; Blanc Mendiberri, Guillermo; Faesi, Christopher; Kruijssen, J. M. Diederik; Meidt, Sharon; Utomo, Dyas; Bigiel, Frank; Bolatto, Alberto; Chevance, Melanie; Chiang, I-Da; Dale, Daniel; Emsellem, Eric; Glover, Simon; Grasha, Kathryn; Henshaw, Jonathan; Herrera, Cinthya; Jiménez Donaire, María Jesús; Lee, Janice; Pety, Jerome; Querejeta, Miguel; Saito, Toshiki; Sandstrom, Karin; Usero, Antonio (IOP, 2020)
      We compare the observed turbulent pressure in molecular gas, P-turb, to the required pressure for the interstellar gas to stay in equilibrium in the gravitational potential of a galaxy, P-DE. To do this, we combine arcsecond ...
    • Star Formation Efficiency per Free-fall Time in nearby Galaxies 
      Utomo, Dyas; Sun, Jiayi; Leroy, Adam; Kruijssen, Diederik; Schinnerer, Eva; Schruba, Andreas; Bigiel, Frank; Blanc Mendiberri, Guillermo; Chevance, Mélanie; Emsellem, Eric; Herrera, Cinthya; Hygate, Alexander; Kreckel, Kathryn; Ostriker, Eve; Pety, Jerome; Querejeta, Miguel; Rosolowsky, Erik; Sandstro, Karin; Usero, Antonio (Institute of Physics Publishing, 2018)
      We estimate the star formation efficiency per gravitational free-fall time, Eff, from observations of nearby galaxies with resolution matched to the typical size of a giant molecular cloud. This quantity, ff, is theoretically ...
    • The headlight cloud in NGC 628: An extreme giant molecular cloud in a typical galaxy disk 
      Herrera, Cinthya N.; Pety, Jerome; Hughes, Annie; Meidt, Sharon E.; Kreckel, Kathryn; Querejeta, Miguel; Saito, Toshiki; Lang, Philipp; Jiménez Donaire, María Jesús; Pessa, Ismael; Cormier, Diane; Usero, Antonio; Sliwa, Kazimierz; Faesi, Christopher; Blanc, Guillermo; Bigiel, Frank; Chevance, Melanie; Dale, Daniel A.; Grasha, Kathryn; Glover, Simon C. O.; Hygate, Alexander P. S; Diederik Kruijssen, J. M.; Leroy, Adam K.; Rosolowsky, Erik; Schinnerer, Eva; Schruba, Andreas; Sun, Jiayi; Utomo, Dyas (EDP Sciences, 2020)
      Context. Cloud-scale surveys of molecular gas reveal the link between giant molecular cloud properties and star formation across a range of galactic environments. Cloud populations in galaxy disks are considered to be ...
    • The lifecycle of molecular clouds in nearby star-forming disc galaxies 
      Chevance, Melanie; Kruijssen, J. M. Diederik; Hygate, Alexander; Schruba, Adreas; Longmore, Steven; Groves, Brent; Henshaw, Jonathan; Herrera, Cinthya; Hughes, Annie; Jeffreson, Sarah; Lang, Philipp; Leroy, Adam; Meidt, Sharon; Pety, Jerome; Razza, Alessandro; Rosolowsky, Erik; Schinnerer, Eva; Bigiel, Frank; Blanc Mendiberri, Guillermo; Emsellem, Eric; Faesi, Christopher; Glover, Simon; Haydon, Daniel; Ho, I-Ting; Kreckel, Kathryn; Lee, Janice; Liu, Daizhong; Querejeta, Miguel; Saito, Toshiki; Sun, Jiayi; Usero, Antonio; Utomo, Dyas (Oxford University Press, 2020)
    • Ubiquitous velocity fluctuations throughout the molecular interstellar medium 
      Henshaw, Jonathan D.; Kruijssen, J. M. Diederik; Longmore, Steven N.; Riener, Manuel; Leroy, Adam K.; Rosolowsky, Erik; Ginsburg, Adam; Battersby, Cara; Chevance, Melanie; Meidt, Sharon E.; Glover, Simon C.O.; Hughes, Annie; Kainulainen, Jouni; Klessen, Ralf S.; Schinnerer, Eva; Schruba, Andreas; Beuther, Henrik; Bigiel, Frank; Neville Blanc Mendiberri, Guillermo; Emsellem, Eric; Henning, Thomas; Herrera, Cynthia N.; Koch, Eric W.; Pety, Jerome; Ragan, Sarah E.; Sun, Jiayi (Nature, 2020)
      Statistical analysis of velocity fluctuations in the interstellar medium (ISM) of the Milky Way and NGC 4321 show that the motion of molecular gas over scales ranging from 0.1 to 1,000 pc is similar, and consistent with ...
