The Hidden Life of Stars: Embedded Beginnings to AGB Endings in the PHANGS-JWST Sample. I. Catalog of Mid-IR Sources

Hamid Hassani, Erik Rosolowsky, Adam K. Leroy +28

We present a multiwavelength catalog of mid-infrared-selected compact sources in 19 nearby galaxies, combining JWST NIRCam/MIRI, HST UV-optical broadband, H narrow-band, and AL…

Evolved Supergiants in PHANGS I: Red Supergiants in 19 Galaxies between 5-20 Mpc with HST and JWST

Sumit K. Sarbadhicary, David Thilker, Adam K. Leroy +17

Red supergiants (RSGs) are important for our understanding of supernova progenitors, stellar populations, stellar evolution, mass loss and dust production. Extragalactic surveys of…

Ashes of Creation: JWST Uncovers Silicate Dust in Massive Star Clusters

Daniel Maschmann, Bradley C. Whitmore, David A. Thilker +35

Dust production is a fundamental aspect of the baryonic cycle of star formation. It is known that dust is injected into the interstellar medium during early star formation by super…

The PHANGS-MUSE/HST-Halpha Nebulae Catalogue

A. T. Barnes, R. Chandar, K. Kreckel +38

We present the PHANGS-MUSE/HST-Halpha nebulae catalogue, comprising 5177 spatially resolved nebulae across 19 nearby star-forming galaxies (< 20 Mpc), based on high-resolution Halp…

Molecular gas in a system of two interacting galaxies overlapping on the line-of-sight

Anaëlle Halle, Barbara Mazzilli Ciraulo, Daniel Maschmann +2

Galaxy interactions can disturb gas in galactic discs, compress it, excite it, and enhance star formation. An intriguing system likely consisting of two interacting galaxies overla…

Empirical SED Templates for Star Clusters Observed with HST and JWST: No Strong PAH or IR Dust Emission after Five Myr

Bradley C. Whitmore, Rupali Chandar, Janice C. Lee +25

JWST observations, when combined with HST data, promise to improve age estimates of star clusters in nearby spiral galaxies. However, feedback from young cluster stars pushes out t…
