A clump population framework for star formation across galactic scales

J. W. Zhou, Sami Dib, Tie Liu +11

Whether star formation across different spatial scales and galactic environments follows universal laws remains poorly understood. We investigate cloud-scale star formation in 30 d…

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…

Mid-Infrared Colors Vary with Galactic Environment: Contrasting Star-Forming Disks, Young Centers, and Quiescent Star-Formation Deserts

Debosmita Pathak, Karin M. Sandstrom, Adam K. Leroy +27

We present pc-resolution JWST/MIRI and NIRCam measurements of mid-infrared (mid-IR) color variations in the diffuse interstellar medium (ISM) of 71 nearby star-forming…

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…

Uncovering the multi-scale structure of dust distribution in nearby galaxies

E. Tanchon, M. Boquien, J. Chastenet +18

High-resolution JWST-MIRI images now allow us to resolve in great detail the multi-scale nature of the emission in nearby star-forming galaxies, from compact star-forming regions t…

The PHANGS-Hα survey. Ground-based narrow-band imaging of nearby star-forming galaxies

Alessandro Razza, Guillermo A. Blanc, Brent Groves +36

We present PHANGS-Hα, a narrow-band imaging survey that maps Hα emission over a sample of 65 nearby massive star-forming galaxies. The data were obtained using the MPG-ESO 2.2-mete…

The lifetime of 100,000 molecular clouds in the nearby Universe

Z. Bazzi, M. I. N. Kobayashi, D. Colombo +25

Multiple mechanisms are proposed for the formation of giant molecular clouds (GMCs), from gravitational free-fall caused by self-gravity to stellar feedback-driven gas compression.…

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.…

Resolved molecular gas and star-formation in massive unquenched spirals : I. UGC 8179

Romane Cologni, Simon Flesch, Philippe Salomé +7

Recent studies have uncovered a rare population of super-massive (M* > 1e11 Msun) star-forming spiral galaxies, Super Spiral Galaxies (SSGs), whose existence challenges classical q…

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…

Euclid: Early Release Observations -- The star-formation history of massive early-type galaxies in the Perseus cluster

S. Martocchia, A. Boselli, J. -C. Cuillandre +157

The Euclid Early Release Observations (ERO) programme targeted the Perseus galaxy cluster in its central region over 0.7deg. We combined the exceptional image quality and depth…

The Nuclear Star Cluster of M 74: a fossil record of the very early stages of a star-forming galaxy

Francesca Pinna, Nils Hoyer, Jairo Méndez Abreu +13

Nuclear star clusters (NSC) are dense and compact stellar systems, of sizes of few parsecs, located at galactic centers. Their properties and formation mechanisms seem to be tightl…

H Morphologies of Star Clusters in 16 LEGUS Galaxies: Constraints on HII region evolution timescales

Stephen Hannon, Janice C. Lee, Bradley C. Whitmore +14

The analysis of star cluster ages in tandem with the morphology of their HII regions can provide insight into the processes that clear a cluster's natal gas, as well as the accurac…

Differences and similarities of stellar populations in LAEs and LBGs at 3.4 - 6.8

P. Arrabal Haro, J. M. Rodríguez Espinosa, C. Muñoz-Tuñón +6

The differences between the inherent stellar populations (SPs) of LAEs and LBGs are a key factor in understanding early galaxy formation and evolution. We have run a set of SP burs…
