    • 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 ...
    • Cloud-scale molecular gas properties in 15 nearby galaxies 
      Sun, Jiayi; Leroy, Adam K.; Schruba, Andreas; Rosolowsky, Erik; Hughes, Annie; Kruijssen, J. M. Diederik; Meidt, Sharon; Schinnerer, Eva; Blanc Mendiberri, Guillermo; Bigiel, Frank; Chevance, Melanie; Groves, Brent; Herrera, Cinthya N.; Hygate, Alexander P. S.; Pety, Jerome; Querejeta, Miguel; Usero, Antonio; Utomo, Dyas; Bolatto, Alberto D. (The American Astronomical Society, 2018-06-20)
      We measure the velocity dispersion, sigma, and surface density, Sigma, of the molecular gas in nearby galaxies from CO spectral line cubes with spatial resolution 45-120. pc, matched to the size of individual giant molecular ...
    • 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 ...
    • Measuring the mixing scale of the ISM within nearby spiral galaxies 
      Kreckel, Kathryn; Ho, I-Ting; Blanc Mendiberri, Guillermo; Glover, Simon C.O.; Groves, Brent; Rosolowsky, Erik; Bigiel, Frank; Boquien, Mederic; Chevance, Melanie; Dale, Daniel A.; Deger, Sinan; Emsellem, Eric; Grasha, Kathryn; Kim, Jenny J.; Klessen, Ralf S.; Kruijssen, J. M. Diederik; Lee, Janice C.; Leroy, Adam K.; Liu, Daizhong; McElroy, Rebecca; Meidt, Sharon E.; Pessa, Ismael; Sánchez Blázquez, Patricia; Sandstrom, Karin; Santoro, Francesco; Scheuermann, Fabian; Schinnerer, Eva; Schruba, Andreas; Utomo, Dyas; Watkins, Elizabeth J.; Williams, Thomas G. (Oxford University Press, 2020)
      The spatial distribution of metals reflects, and can be used to constrain, the processes of chemical enrichment and mixing. Using PHANGS-MUSE optical integral field spectroscopy, we measure the gas-phase oxygen abundances ...

      Sun, Jiayi; Leroy, Adam K.; Schinnerer, Eva; Hughes, Annie; Rosolowsky, Erik; Querejeta, Miguel; Schruba, Andreas; Liu, Daizhong; Saito, Toshiki; Herrera, Cinthya N.; Faesi, Christopher; Usero, Antonio; Pety, Jérôme; Kruijssen, J. M. Diederik; Ostriker, Eve C.; Bigiel, Frank; Blanc Mendiberri, Guillermo; Bolatto, Alberto D.; Boquien, Médéric; Chevance, Mélanie; Dale, Daniel A.; Deger, Sinan; Emsellem, Eric; Glover, Simon C.O.; Grasha, Kathryn; Groves, Brent; Henshaw, Jonathan; Jiménez Donaire, María J.; Kim, Jenny J.; Klessen, Ralf S.; Kreckel, Kathryn; Lee, Janice C.; Meidt, Sharon; Sandstrom, Karin; Sardone, Amy E.; Utomo, Dyas; Williams, Thomas G. (IOP Publishing, 2020)
      Using the PHANGS-ALMA CO(2-1) survey, we characterize molecular gas properties on similar to 100 pc scales across 102,778 independent sightlines in 70 nearby galaxies. This yields the best synthetic view of molecular gas ...
    • 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
