HCN emission from translucent gas and UV-illuminated cloud edges revealed by wide-field IRAM 30m maps of Orion B GMC: Revisiting its role as tracer of the dense gas reservoir for star formation
M. G. Santa-Maria, J. R. Goicoechea, J. Pety +28
We present 5 deg^2 (~250 pc^2) HCN, HNC, HCO+, and CO J=1-0 maps of the Orion B GMC, complemented with existing wide-field [CI] 492 GHz maps, as well as new pointed observations of…
Neural network-based emulation of interstellar medium models
Pierre Palud, Lucas Einig, Franck Le Petit +22
The interpretation of observations of atomic and molecular tracers in the galactic and extragalactic interstellar medium (ISM) requires comparisons with state-of-the-art astrophysi…
A constant NH(1-0)-to-HCN(1-0) ratio on kiloparsec scales
M. J. Jiménez-Donaire, A. Usero, I. Bešlić +24
Nitrogen hydrides such as NH and NH are widely used by Galactic observers to trace the cold dense regions of the interstellar medium. In external galaxies, because of l…
Deep learning denoising by dimension reduction: Application to the ORION-B line cubes
Lucas Einig, Jérôme Pety, Antoine Roueff +29
Context. The availability of large bandwidth receivers for millimeter radio telescopes allows the acquisition of position-position-frequency data cubes over a wide field of view an…
The impact of HII regions on Giant Molecular Cloud properties in nearby galaxies sampled by PHANGS ALMA and MUSE
Antoine Zakardjian, Jérôme Pety, Cinthya N. Herrera +36
We identify giant molecular clouds (GMCs) associated with HII regions for a sample of 19 nearby galaxies using catalogs of GMCs and H regions released by the PHANGS-ALMA and PHANGS…
Wide-field CO isotopologue emission and the CO-to-H factor across the nearby spiral galaxy M101
Jakob S. den Brok, Frank Bigiel, Jérémy Chastenet +18
Carbon monoxide (CO) emission is the most widely used tracer of the bulk molecular gas in the interstellar medium (ISM) in extragalactic studies. The CO-to-H conversion factor,…
