Star Cluster Populations in 38 Spiral Galaxies: Evidence for Near-Universal Mass and Age Distributions from PHANGS

Rupali Chandar, Matthew R. Floyd, David A. Thilker +23

We present the largest study to date of star cluster mass and age distributions in nearby galaxies. The analysis is based on a uniformly selected catalog of over 15,000 (36,000) hu…

Quantifying the decline in CO(2-1) intensity around PHANGS-HST star clusters: Constraints on molecular gas dispersal, stellar feedback, and cluster formation efficiency

Hao He, Adam K. Leroy, Erik Rosolowsky +37

We combine the largest survey of star clusters in nearby galaxies to-date, PHANGS-HST, with maps of molecular gas maps from PHANGS-ALMA to constrain the efficiency of cluster forma…

Variations in the 3.3 m Polycyclic Aromatic Hydrocarbon Feature Across Nearby Galaxies Driven by Metallicity and Radiation Field Spectrum

Hannah B. Koziol, Karin Sandstrom, Dalya Baron +29

We use JWST NIRCam imaging to investigate the 3.3 m polycyclic aromatic hydrocarbon (PAH) feature in nearby galaxies. NIRCam observations of the 3.3 m feature are emerging as…

A steep mass transition for bar-driven ISM structuring revealed by PHANGS-JWST

Eric Emsellem, Jessica Sutter, Ryan Chown +26

Galactic bars play a critical role in the secular evolution of their hosts by reorganising the ISM. We use a sample of 57 star-forming disc galaxies observed with JWST at 3 and 7.7…

To What Extent Are Star Cluster Ages Encoded in Their Environments? Exploring the Spatial Distribution of Age-Related Information with PHANGS-HST Imaging and Convolutional Neural Networks

Javier Viaña, Janice C. Lee, Andrew Vanderburg +12

The environments around star clusters evolve as stellar feedback reshapes the interstellar medium and dynamical processes reorganize the structure of the surrounding stellar field.…

Stellar associations powering HII regions $\unicode{x2013}$ II. Escape fraction of ionizing photons

Fabian Scheuermann, Kathryn Kreckel, Jia Wei Teh +27

Newly formed stars have a profound impact on their environment by depositing energy and momentum into the surrounding gas. However, only a fraction of the stellar feedback is retai…
