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…

Tracers of the ionization fraction in dense and translucent molecular gas: II. Using mm observations to constrain ionization fraction across Orion B

Ivana Bešlić, Maryvonne Gerin, Viviana V. Guzmán +28

The ionization fraction () is a crucial parameter of interstellar gas, yet estimating it requires deep knowledge of molecular gas chemistry…

Beetroots: spatially-regularized Bayesian inference of physical parameter maps -- Application to Orion

Pierre Palud, Emeric Bron, Pierre Chainais +28

The current generation of millimeter receivers is able to produce cubes of 800 000 pixels by 200 000 frequency channels to cover several square degrees over the 3 mm atmospheric wi…

Estimating the dense gas mass of molecular clouds using spatially unresolved 3 mm line observations

Antoine Zakardjian, Annie Hughes, Jérôme Pety +28

We aim to develop a new method to infer the sub-beam probability density function (PDF) of H2 column densities and the dense gas mass within molecular clouds using spatially unreso…

Toward a robust physical and chemical characterization of heterogeneous lines of sight: The case of the Horsehead nebula

Léontine Ségal, Antoine Roueff, Jérôme Pety +28

Dense cold molecular cores/filaments are surrounded by an envelope of translucent gas. Some of the low-J emission lines of CO and HCO isotopologues are more sensitive to the co…

Quantifying the informativity of emission lines to infer physical conditions in giant molecular clouds. I. Application to model predictions

Lucas Einig, Pierre Palud, Antoine Roueff +29

Observations of ionic, atomic, or molecular lines are performed to improve our understanding of the interstellar medium (ISM). However, the potential of a line to constrain the phy…

Bias versus variance when fitting multi-species molecular lines with a non-LTE radiative transfer model

Antoine Roueff, Jérôme Pety, Maryvonne Gerin +28

Robust radiative transfer techniques are requisite for efficiently extracting the physical and chemical information from molecular rotational lines.We study several hypotheses that…

The magnetic field in the Flame nebula

Ivana Bešlić, Simon Coudé, Dariusz C. Lis +14

Star formation is essential in galaxy evolution and the cycling of matter. The support of interstellar clouds against gravitational collapse by magnetic (B-) fields has been propos…

A sensitive, high-resolution, wide-field IRAM NOEMA CO(1-0) survey of the very nearby spiral galaxy IC 342

M. Querejeta, J. Pety, A. Schruba +31

We present a new wide-field 10.75 x 10.75 arcmin^2 (~11x11 kpc^2), high-resolution (theta = 3.6" ~ 60 pc) NOEMA CO(1-0) survey of the very nearby (d=3.45 Mpc) spiral galaxy IC 342.…

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…

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…

The XMM-Newton serendipitous survey IX. The fourth XMM-Newton serendipitous source catalogue

N. A. Webb, M. Coriat, I. Traulsen +28

Sky surveys produce enormous quantities of data on extensive regions of the sky. The easiest way to access this information is through catalogues of standardised data products. {\e…
