  • Dense gas in a giant molecular filament 
    Wang, Y.; Beuther, H.; Schneider, N.; Meidt, S. E.; Linz, H.; Ragan, S.; Zucker, Catherine; Battersby, C.; Soler, J. D.; Schinnerer, E.; Bigiel, F.; Colombo, D.; Henning, Th (2020)
    Context. Recent surveys of the Galactic plane in the dust continuum and CO emission lines reveal that large (?50 pc) and massive (?10<SUP>5</SUP> M<SUB>?</SUB>) filaments, know as giant molecular filaments (GMFs), may be ...
  • Dense gas is not enough: environmental variations in the star formation efficiency of dense molecular gas at 100 pc scales in M 51 
    Querejeta, M.; Schinnerer, E.; Schruba, A.; Murphy, E.; Meidt, S.; Usero, A.; Leroy, A. K.; Pety, J.; Bigiel, F.; Chevance, M.; Faesi, C. M.; Gallagher, M.; García-Burillo, S.; Glover, S. C. O.; Hygate, A. P. S.; Jiménez-Donaire, M. J.; Kruijssen, J. M. D.; Momjian, E.; Rosolowsky, E.; Utomo, D. (2019)
    It remains unclear what sets the efficiency with which molecular gas transforms into stars. Here we present a new VLA map of the spiral galaxy M 51 in 33 GHz radio continuum, an extinction-free tracer of star formation, ...
  • EMPIRE: The IRAM 30 m Dense Gas Survey of Nearby Galaxies 
    Jiménez-Donaire, María J.; Bigiel, F.; Leroy, A. K.; Usero, A.; Cormier, D.; Puschnig, J.; Gallagher, M.; Kepley, A.; Bolatto, A.; García-Burillo, S.; Hughes, A.; Kramer, C.; Pety, J.; Schinnerer, E.; Schruba, A.; Schuster, K.; Walter, F. (2019)
    We present EMPIRE, an IRAM 30 m large program that mapped ? = 3-4 mm dense gas tracers at ~1-2 kpc resolution across the whole star-forming disk of nine nearby massive spiral galaxies. We describe the EMPIRE observing and ...
  • Histogram of oriented gradients: a technique for the study of molecular cloud formation 
    Soler, J. D.; Beuther, H.; Rugel, M.; Wang, Y.; Clark, P. C.; Glover, S. C. O.; Goldsmith, P. F.; Heyer, M.; Anderson, L. D.; Goodman, Alyssa A.; Henning, Th; Kainulainen, J.; Klessen, R. S.; Longmore, S. N.; McClure-Griffiths, N. M.; Menten, K. M.; Mottram, J. C.; Ott, J.; Ragan, S. E.; Smith, R. J.; Urquhart, J. S.; Bigiel, F.; Hennebelle, P.; Roy, N.; Schilke, P. (2019)
    We introduce the histogram of oriented gradients (HOG), a tool developed for machine vision that we propose as a new metric for the systematic characterization of spectral line observations of atomic and molecular gas and ...
  • PHANGS-JWST First Results: A Global and Moderately Resolved View of Mid-infrared and CO Line Emission from Galaxies at the Start of the JWST Era 
    Leroy, Adam K.; Bolatto, Alberto D.; Sandstrom, Karin; Rosolowsky, Erik; Barnes, Ashley T.; Bigiel, F.; Boquien, Médéric; den Brok, Jakob S.; Cao, Yixian; Chastenet, Jérémy; Chevance, Mélanie; Chiang, I-Da; Chown, Ryan; Colombo, Dario; Ellison, Sara L.; Emsellem, Eric; Grasha, Kathryn; Henshaw, Jonathan D.; Hughes, Annie; Klessen, Ralf S.; Koch, Eric W.; Kim, Jaeyeon; Kreckel, Kathryn; Kruijssen, J. M. Diederik; Larson, Kirsten L.; Lee, Janice C.; Levy, Rebecca C.; Lin, Lihwai; Liu, Daizhong; Meidt, Sharon E.; Pety, Jérôme; Querejeta, Miguel; Rubio, Mónica; Saito, Toshiki; Salim, Samir; Schinnerer, Eva; Sormani, Mattia C.; Sun, Jiayi; Thilker, David A.; Usero, Antonio; Vogel, Stuart N.; Watkins, Elizabeth J.; Whitcomb, Cory M.; Williams, Thomas G.; Wilson, Christine D. (2023)
    We explore the relationship between mid-infrared (mid-IR) and CO rotational line emission from massive star-forming galaxies, which is one of the tightest scalings in the local universe. We assemble a large set of unresolved ...
  • PHANGS-JWST First Results: Interstellar Medium Structure on the Turbulent Jeans Scale in Four Disk Galaxies Observed by JWST and the Atacama Large Millimeter/submillimeter Array 
    Meidt, Sharon E.; Rosolowsky, Erik; Sun, Jiayi; Koch, Eric W.; Klessen, Ralf S.; Leroy, Adam K.; Schinnerer, Eva; Barnes, Ashley T.; Glover, Simon C. O.; Lee, Janice C.; van der Wel, Arjen; Watkins, Elizabeth J.; Williams, Thomas G.; Bigiel, F.; Boquien, Médéric; Blanc, Guillermo A.; Cao, Yixian; Chevance, Mélanie; Dale, Daniel A.; Egorov, Oleg V.; Emsellem, Eric; Grasha, Kathryn; Henshaw, Jonathan D.; Kruijssen, J. M. Diederik; Larson, Kirsten L.; Liu, Daizhong; Murphy, Eric J.; Pety, Jérôme; Querejeta, Miguel; Saito, Toshiki; Sandstrom, Karin M.; Smith, Rowan J.; Sormani, Mattia C.; Thilker, David A. (2023)
    JWST/Mid-Infrared Instrument imaging of the nearby galaxies IC 5332, NGC 628, NGC 1365, and NGC 7496 from PHANGS reveals a richness of gas structures that in each case form a quasi-regular network of interconnected filaments, ...
  • Variations in the S<SUB>SFR</SUB> - S<SUB>mol</SUB> - S<SUB>?</SUB> plane across galactic environments in PHANGS galaxies 
    Pessa, I.; Schinnerer, E.; Leroy, A. K.; Koch, Eric W.; Rosolowsky, E.; Williams, T. G.; Pan, H. -A; Schruba, A.; Usero, A.; Belfiore, F.; Bigiel, F.; Blanc, G. A.; Chevance, M.; Dale, D.; Emsellem, E.; Gensior, J.; Glover, S. C. O.; Grasha, K.; Groves, B.; Klessen, R. S.; Kreckel, K.; Kruijssen, J. M. D.; Liu, D.; Meidt, S. E.; Pety, J.; Querejeta, M.; Saito, T.; Sanchez-Blazquez, P.; Watkins, E. J. (2022)
    <br/> Aims: There exists some consensus that the stellar mass surface density (S<SUB>?</SUB>) and molecular gas mass surface density (S<SUB>mol</SUB>) are the main quantities responsible for locally setting the star formation ...
