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

Adam K. Leroy, Alberto D. Bolatto, Karin Sandstrom +41

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 uni…

PHANGS-JWST First Results: Stellar Feedback-Driven Excitation and Dissociation of Molecular Gas in the Starburst Ring of NGC 1365?

Daizhong Liu, Eva Schinnerer, Yixian Cao +36

We compare embedded young massive star clusters (YMCs) to (sub-)millimeter line observations tracing the excitation and dissociation of molecular gas in the starburst ring of NGC 1…

PHANGS-JWST First Results: Rapid Evolution of Star Formation in the Central Molecular Gas Ring of NGC1365

Eva Schinnerer, Eric Emsellem, Jonathan D. Henshaw +36

Large-scale bars can fuel galaxy centers with molecular gas, often leading to the development of dense ring-like structures where intense star formation occurs, forming a very diff…

PHANGS--JWST First Results: ISM structure on the turbulent Jeans scale in four disk galaxies observed by JWST and ALMA

Sharon E. Meidt, Erik Rosolowsky, Jiayi Sun +31

JWST/MIRI 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…

PHANGS-JWST First Results: Duration of the early phase of massive star formation in NGC628

Jaeyeon Kim, Mélanie Chevance, J. M. Diederik Kruijssen +33

The earliest stages of star formation, when young stars are still deeply embedded in their natal clouds, represent a critical phase in the matter cycle between gas clouds and young…

PHANGS-JWST First Results: Multi-wavelength view of feedback-driven bubbles (The Phantom Voids) across NGC 628

Ashley T. Barnes, Elizabeth J. Watkins, Sharon E. Meidt +51

We present a high-resolution view of bubbles within The Phantom Galaxy (NGC 628); a nearby (~10Mpc), star-forming (~2Msun/yr), face-on (i~9deg) grand-design spiral galaxy. With new…

PHANGS-JWST First Results: A statistical view on bubble evolution in NGC628

Elizabeth J. Watkins, Ashley Barnes, Kiana F. Henny +49

The first JWST observations of nearby galaxies have unveiled a rich population of bubbles that trace the stellar feedback mechanisms responsible for their creation. Studying these…

PHANGS-JWST First Results: Spurring on Star Formation: JWST Reveals Localised Star Formation in a Spiral Arm Spur of NGC 628

Thomas G. Williams, Jiayi Sun, Ashley T. Barnes +34

We combine JWST observations with ALMA CO and VLT-MUSE H data to examine off-spiral arm star formation in the face-on, grand-design spiral galaxy NGC 628. We focus on the northe…

Gas kinematics around filamentary structures in the Orion B cloud

Mathilde Gaudel, Jan H. Orkisz, Maryvonne Gerin +27

Understanding the initial properties of star-forming material and how they affect the star formation process is key. From an observational point of view, the feedback from young hi…

A Global View on Star Formation: The GLOSTAR Galactic Plane Survey V. 6.7 GHz Methanol Maser Catalogue

H. Nguyen, M. R. Rugel, C. Murugeshan +15

Class II methanol (CHOH) masers are amongst the clearest signposts of recent high-mass star formation (HMSF). A complete catalogue outlines the distribution of star formation…

Environmental dependence of the molecular cloud lifecycle in 54 main sequence galaxies

Jaeyeon Kim, Mélanie Chevance, J. M. Diederik Kruijssen +27

The processes of star formation and feedback, regulating the cycle of matter between gas and stars on the scales of giant molecular clouds (GMCs; 100pc), play a major role in…

A multiwavelength study of the W33 Main ultracompact HII region

Sarwar Khan, Jagadheep D. Pandian, Dharam V. Lal +7

The dynamics of ionized gas around the W33 Main ultracompact HII region is studied using observations of hydrogen radio recombination lines and a detailed multiwavelength character…

The science case and challenges of space-borne sub-millimeter interferometry

Leonid I. Gurvits, Zsolt Paragi, Ricardo I. Amils +51

Ultra-high angular resolution in astronomy has always been an important vehicle for making fundamental discoveries. Recent results in direct imaging of the vicinity of the supermas…
