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…
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…
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…
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-me…
The impact of bars on the properties of HII regions in the TIMER survey
Laura Sánchez-Menguiano, Dimitri A. Gadotti, Almudena Zurita +10
In this study we perform a comparative analysis of the properties of the HII regions located in different areas of barred galaxies, with the aim of investigating the impact of bars…
The evolution of the bar fraction and bar lengths in the last 12 billion years
Zoe A. Le Conte, Dimitri A. Gadotti, Leonardo Ferreira +7
We investigate the evolution of the bar fraction and length using an extended JWST NIRCam imaging dataset of galaxies at . We assess the wavelength dependence of t…
