Chemical diversity of dense cores in Orion B: The role of the environment
Helena J. Mazurek, Maryvonne Gerin, Pierre Gratier +26
Prestellar cores are the sites of the earliest stages of star formation. Dust continuum observations are often used to identify and characterize their properties yet only a small f…
From gas to stars along the spiral wave: CO, HCN, and star formation variations across the spiral arms in NGC 4321 and M51
Minou Greve, Lukas Neumann, Mallory Thorp +17
Molecular clouds form stars from the interstellar medium via gravitational collapse, following a sequence from low-density gas to high-density cores and eventually the formation of…
Surveying the Whirlpool at Arcseconds with NOEMA (SWAN). IV. Extent of active galactic nucleus feedback on the interstellar medium
Mallory D. Thorp, Antonio Usero, Frank Bigiel +19
Active Galactic Nuclei (AGN) are intertwined with galaxy evolution, injecting energy into the interstellar medium (ISM) that could regulate star formation as a galaxy evolves. Howe…
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…
Spatial distribution of organics in the Horsehead nebula: Signposts of chemistry driven by atomic carbon
Claudio Hernández-Vera, Viviana V. Guzmán, Jérôme Pety +10
(Abridged) Complex organic molecules (COMs) are considered essential precursors to prebiotic species. While COMs were once expected to be efficiently destroyed under UV-irradiated…
The Hierarchical Dynamical State of Molecular Gas from 3 to 300 pc in NGC 253
Elias K. Oakes, Christopher M. Faesi, Erik Rosolowsky +25
Understanding how the dynamical state of the interstellar medium (ISM) changes across spatial scales can provide important insights into how the gas is organized and ultimately col…
