The PHANGS-AstroSat Atlas of Nearby Star Forming Galaxies
Hamid Hassani, Erik Rosolowsky, Eric W. Koch +29
We present the Physics at High Angular resolution in Nearby GalaxieS (PHANGS)-AstroSat atlas, which contains ultraviolet imaging of 31 nearby star-forming galaxies captured by the…
Investigating the Drivers of Electron Temperature Variations in HII Regions with Keck-KCWI and VLT-MUSE
Ryan J. Rickards Vaught, Karin M. Sandstrom, Francesco Belfiore +12
HII region electron temperatures are a critical ingredient in metallicity determinations and recent observations reveal systematic variations in the temperatures measured using dif…
Quantifying the energy balance between the turbulent ionised gas and young stars
Oleg V. Egorov, Kathryn Kreckel, Simon C. O. Glover +19
We investigate the ionised gas morphology, excitation properties, and kinematics in 19 nearby star-forming galaxies from the PHANGS-MUSE survey. We directly compare the kinetic ene…
Physical parameters of stellar population in star formation regions of galaxies
A. S. Gusev, F. Sakhibov, O. V. Egorov +2
We present the results of a study of young unresolved stellar groupings (clusters, OB associations, and their complexes) associated with HII regions, based on the coupling of spect…
Calibrating mid-infrared emission as a tracer of obscured star formation on HII-region scales in the era of JWST
Francesco Belfiore, Adam K. Leroy, Thomas G. Williams +25
Measurements of the star formation activity on cloud scales are fundamental to uncovering the physics of the molecular cloud, star formation, and stellar feedback cycle in galaxies…
Density biases and temperature relations for DESIRED HII regions
J. E. Méndez-Delgado, C. Esteban, J. García-Rojas +6
We present a first study based on the analysis of the DEep Spectra of Ionized REgions Database (DESIRED). This is a compilation of 190 high signal-to-noise ratio optical spectra of…
Stellar associations powering HII regions $\unicode{x2013}$ I. Defining an evolutionary sequence
Fabian Scheuermann, Kathryn Kreckel, Ashley T. Barnes +30
Connecting the gas in HII regions to the underlying source of the ionizing radiation can help us constrain the physical processes of stellar feedback and how HII regions evolve ove…
PHANGS-MUSE: Detection and Bayesian classification of ~40000 ionised nebulae in nearby spiral galaxies
Enrico Congiu, Guillermo A. Blanc, Francesco Belfiore +15
In this work, we present a new catalogue of >40000 ionised nebulae distributed across the 19 galaxies observed by the PHANGS-MUSE survey. The nebulae have been classified using a n…
Quantifying the energetics of molecular superbubbles in PHANGS galaxies
E. J. Watkins, K. Kreckel, B. Groves +26
Star formation and stellar feedback are interlinked processes that redistribute energy and matter throughout galaxies. When young, massive stars form in spatially clustered environ…
Serendipitous Nebular-phase JWST Imaging of SN Ia 2021aefx: Testing the Confinement of 56-Co Decay Energy
Ness Mayker Chen, Michael A. Tucker, Nils Hoyer +29
We present new 0.3-21 micron photometry of SN 2021aefx in the spiral galaxy NGC 1566 at +357 days after B-band maximum, including the first detection of any SN Ia at >15 micron. Th…
The PHANGS-MUSE Nebula Catalogue
B. Groves, K. Kreckel, F. Santoro +17
Ionized nebulae provide critical insights into the conditions of the interstellar medium (ISM). Their bright emission lines enable the measurement of physical properties, such as t…
PHANGS-JWST First Results: Mid-infrared emission traces both gas column density and heating at 100 pc scales
Adam K. Leroy, Karin Sandstrom, Erik Rosolowsky +48
We compare mid-infrared (mid-IR), extinction-corrected H, and CO (2-1) emission at 70--160 pc resolution in the first four PHANGS-JWST targets. We report correlation strengths,…
PHANGS-JWST First Results: Variations in PAH Fraction as a Function of ISM Phase and Metallicity
Jérémy Chastenet, Jessica Sutter, Karin Sandstrom +26
We present maps tracing the fraction of dust in the form of polycyclic aromatic hydrocarbons (PAHs) in IC 5332, NGC 628, NGC 1365, and NGC 7496 from JWST/MIRI observations. We trac…
