Molecular outflows in local galaxies: Method comparison and a role of intermittent AGN driving
D. Lutz, E. Sturm, A. Janssen +17
We report new detections and limits from a NOEMA and ALMA CO(1-0) search for molecular outflows in 13 local galaxies with high FIR surface brightness, and combine with results from…
The lifecycle of molecular clouds in nearby star-forming disc galaxies
Mélanie Chevance, J. M. Diederik Kruijssen, Alexander P. S. Hygate +29
It remains a major challenge to derive a theory of cloud-scale ( pc) star formation and feedback, describing how galaxies convert gas into stars as a function of the g…
The headlight cloud in NGC 628: An extreme giant molecular cloud in a typical galaxy disk
Cinthya N. Herrera, Jérôme Pety, Annie Hughes +25
Cloud-scale surveys of molecular gas reveal the link between molecular clouds properties and star formation (SF) across a range of galactic environments. Cloud populations in galax…
The Gas-Star Formation Cycle in Nearby Star-Forming Galaxies I. Assessment of Multi-scale Variations
Eva Schinnerer, Annie Hughes, Adam Leroy +21
The processes regulating star formation in galaxies are thought to act across a hierarchy of spatial scales. To connect extragalactic star formation relations from global and kpc-s…
Mapping electron temperature variations across a spiral arm in NGC 1672
I-Ting Ho, Kathryn Kreckel, Sharon E. Meidt +17
We report one of the first extragalactic observations of electron temperature variations across a spiral arm. Using MUSE mosaic observations of the nearby galaxy NGC 1672, we measu…
Mapping metallicity variations across nearby galaxy disks
K. Kreckel, I. -T. Ho, G. A. Blanc +21
The distribution of metals within a galaxy traces the baryon cycle and the buildup of galactic disks, but the detailed gas phase metallicity distribution remains poorly sampled. We…
Stellar Feedback and Resolved Stellar IFU Spectroscopy in the nearby Spiral Galaxy NGC 300
Anna F. McLeod, J. M. Diederik Kruijssen, Daniel R. Weisz +7
We present MUSE Integral Field Unit (IFU) observations of five individual HII regions in two giant (>100 pc in radius) star-forming complexes in the low-metallicity (~0.33 $Z_{\…
Deep Transfer Learning for Star Cluster Classification: I. Application to the PHANGS-HST Survey
Wei Wei, E. A. Huerta, Bradley C. Whitmore +13
We present the results of a proof-of-concept experiment which demonstrates that deep learning can successfully be used for production-scale classification of compact star clusters…
How Galactic Environment affects the Dynamical State of Molecular Clouds and their Star Formation Efficiency
Andreas Schruba, J. M. Diederik Kruijssen, Adam K. Leroy
We investigate how the dynamical state of molecular clouds relates to host galaxy environment, and how this impacts the star formation efficiency in the Milky Way and seven nearby…
EMPIRE: The IRAM 30-m Dense Gas Survey of Nearby Galaxies
María J. Jiménez-Donaire, F. Bigiel, A. K. Leroy +14
We present EMPIRE, an IRAM 30-m large program that mapped mm dense gas tracers at kpc resolution across the whole star-forming disk of nine nearby, massive…
Fast and inefficient star formation due to short-lived molecular clouds and rapid feedback
J. M. Diederik Kruijssen, Andreas Schruba, Mélanie Chevance +7
The physics of star formation and the deposition of mass, momentum, and energy into the interstellar medium by massive stars (`feedback') are the main uncertainties in modern cosmo…
Optical IFU spectroscopy of a bipolar microquasar jet in NGC 300
A. F. McLeod, S. Scaringi, R. Soria +9
We recently reported the discovery of a candidate jet-driving microquasar (S10) in the nearby spiral galaxy NGC 300. However, in the absence of kinematic information, we could not…
Relationship between the Line Width of the Atomic and Molecular ISM in M33
Eric W. Koch, Erik W. Rosolowsky, Andreas Schruba +5
We investigate how the spectral properties of atomic (HI) and molecular (H) gas, traced by CO(2-1), are related in M33 on pc scales. We find the HI and CO(2-1) velocity at…
Dense gas is not enough: environmental variations in the star formation efficiency of dense molecular gas at 100pc scales in M51
M. Querejeta, E. Schinnerer, A. Schruba +17
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 M51 in 33GHz radio continuum, an exti…
Simulating the atomic and molecular content of molecular clouds using probability distributions of physical parameters
Thomas G. Bisbas, Andreas Schruba, Ewine F. van Dishoeck
Modern observations of the interstellar medium (ISM) in galaxies detect a variety of atomic and molecular species. The goal is to connect these observations to the astrochemical pr…
