Molecular Gas Properties and CO-to-H2 Conversion Factors in the Central Kiloparsec of NGC 3351
Yu-Hsuan Teng, Karin M. Sandstrom, Jiayi Sun +16
The CO-to-H conversion factor ($α_\rm{CO}$) is critical to studying molecular gas and star formation in galaxies. The value of $α_\rm{CO}$ has been found to vary within and bet…
A census of optically dark massive galaxies in the early Universe from magnification by lensing galaxy clusters
Xinwen Shu, Lei Yang, Daizhong Liu +10
We present ALMA 870um and JCMT SCUBA2 850um dust continuum observations of a sample of optically dark and strongly lensed galaxies in the cluster fields. The ALMA and SCUBA2 observ…
The Two-Dimensional Metallicity Distribution and Mixing Scales of Nearby Galaxies
Thomas G. Williams, Kathryn Kreckel, Francesco Belfiore +25
Understanding the spatial distribution of metals within galaxies allows us to study the processes of chemical enrichment and mixing in the interstellar medium (ISM). In this work,…
The PHANGS-MUSE survey -- Probing the chemo-dynamical evolution of disc galaxies
Eric Emsellem, Eva Schinnerer, Francesco Santoro +45
We present the PHANGS-MUSE survey, a programme using the MUSE IFS at the ESO VLT to map 19 massive nearby (D < 20 Mpc) star-forming disc galaxi…
Low-J CO Line Ratios From Single Dish CO Mapping Surveys and PHANGS-ALMA
Adam K. Leroy, Erik Rosolowsky, Antonio Usero +32
We measure the low-J CO line ratio R21=CO(2-1)/CO(1-0), R32=CO(3-2)/CO(2-1), and R31 = CO(3-2)/CO(1-0) using whole-disk CO maps of nearby galaxies. We draw CO(2-1) from PHANGS--ALM…
The Evolving Interstellar Medium of Star-Forming Galaxies, as traced by
Vasily Kokorev, Georgios Magdis, Iary Davidzon +13
We analyse the far-infrared properties of 5,000 star-forming galaxies at , drawn from the deepest, super-deblended catalogues in the GOODS-N and COSMOS fields. We dev…
The effect of active galactic nuclei on the cold interstellar medium in distant star-forming galaxies
Francesco Valentino, Emanuele Daddi, Annagrazia Puglisi +17
In the framework of a systematic ALMA study of IR-selected main-sequence and starburst galaxies at z~1-1.7 at typical ~1" resolution, we report on the effects of mid-IR- and X-ray-…
PHANGS-ALMA: Arcsecond CO(2-1) Imaging of Nearby Star-Forming Galaxies
Adam K. Leroy, Eva Schinnerer, Annie Hughes +69
We present PHANGS-ALMA, the first survey to map CO J=2-1 line emission at ~1" ~ 100pc spatial resolution from a representative sample of 90 nearby (d<~20 Mpc) galaxies that lie on…
PHANGS-ALMA Data Processing and Pipeline
Adam K. Leroy, Annie Hughes, Daizhong Liu +65
We describe the processing of the PHANGS-ALMA survey and present the PHANGS-ALMA pipeline, a public software package that processes calibrated interferometric and total power data…
The organization of cloud-scale gas density structure: high resolution CO vs. 3.6 m brightness contrasts in nearby galaxies
Sharon E. Meidt, Adam K. Leroy, Miguel Querejeta +29
In this paper we examine the factors that shape the distribution of molecular gas surface densities on the 150 pc scale across 67 morphologically diverse star-forming galaxies in t…
Sub-millimetre compactness as a critical dimension to understand the Main Sequence of star-forming galaxies
Annagrazia Puglisi, Emanuele Daddi, Francesco Valentino +11
We study the interstellar medium (ISM) properties as a function of the molecular gas size for 77 infrared-selected galaxies at . Molecular gas sizes are measured on ALM…
CO excitation, molecular gas density and interstellar radiation field in local and high-redshift galaxies
Daizhong Liu, Emanuele Daddi, Eva Schinnerer +9
We study the Carbon Monoxide (CO) excitation, mean molecular gas density and interstellar radiation field (ISRF) intensity in a comprehensive sample of 76 galaxies from local to hi…
Giant Molecular Cloud Catalogues for PHANGS-ALMA: Methods and Initial Results
Erik Rosolowsky, Annie Hughes, Adam K. Leroy +26
We present improved methods for segmenting CO emission from galaxies into individual molecular clouds, providing an update to the CPROPS algorithms presented by Rosolowsky & Leroy…
A titanic interstellar medium ejection from a massive starburst galaxy at redshift 1.4
Annagrazia Puglisi, Emanuele Daddi, Marcella Brusa +12
Feedback-driven winds from star formation or active galactic nuclei might be a relevant channel for the abrupt quenching star formation in massive galaxies. However, both observati…
The PHANGS-HST Survey: Physics at High Angular resolution in Nearby GalaxieS with the Hubble Space Telescope
Janice C. Lee, Bradley C. Whitmore, David A. Thilker +51
The PHANGS program is building the first dataset to enable the multi-phase, multi-scale study of star formation across the nearby spiral galaxy population. This effort is enabled b…
