DIGging into HII regions: the role of ionizing photon leakage and spectral hardening in coupling HII regions and diffuse ionized gas

Dalya Baron, Kathryn Kreckel, Gwen C. Rudie +15

The optical emission-line ratios of star-forming galaxies are broadly understood in the framework of photoionization, yet some systematic trends remain unexplained. Using 50--100 p…

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…

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-mete…

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…

Gravitational Torques from a Lopsided Young Stellar Component Sustain High Black Hole Accretion Rates in NGC 4593

Nico Winkel, Knud Jahnke, Juan Antonio Fernández-Ontiveros +8

Supermassive black holes (SMBHs) grow primarily through gas accretion, observed as active galactic nuclei (AGNs). While mergers can drive luminous AGN episodes, secular processes m…

Extreme cloud collisions in nearby barred galaxies

Tutku Kolcu, Mattia C. Sormani, Witold Maciejewski +16

The inner regions of the Milky Way are known to contain an enigmatic population of prominent molecular clouds characterised by extremely broad lines. The physical origin of these '…

On the role of non-circular motions in MaNGA galaxies I: global properties

Carlos Lopez-Coba, Lihwai Lin, Justus Neumann +1

Non-circular (NC) motions represent the imprints of non-axisymmetric structures in galaxies, providing opportunities to study the physical properties of gas departing from circular…

The Close AGN Reference Survey (CARS): An interplay between radio jets and AGN radiation in the radio-quiet AGN HE 0040-1105

M. Singha, N. Winkel, S. Vaddi +14

We present a case study of HE 0040-1105, an unobscured radio-quiet AGN at a high accretion rate (Eddington ratio = 0.19+/-0.04). This particular AGN hosts an ionized gas outflow wi…

The Gas Morphology of Nearby Star-Forming Galaxies

S. K. Stuber, E. Schinnerer, T. G. Williams +22

The morphology of a galaxy stems from secular and environmental processes during its evolutionary history. Thus galaxy morphologies have been a long used tool to gain insights on g…
