Revealing Galactic dust beneath the cosmic infrared background anisotropies with Wavelet Phase Harmonics
Srijita Sinha, Tuhin Ghosh, Erwan Allys +2
Separating Galactic dust emission from cosmic infrared background (CIB) anisotropies is challenging because both the emission components have similar spectral properties. The prima…
PDRs4All XXII. Near-Infrared continuum in the Orion Bar
Takashi Onaka, Emmanuel Dartois, Els Peeters +13
Conspicuous excess emission is present in the near-infrared (NIR) region in various objects, including reflection nebulae, planetary nebulae, and nearby galaxies. However, the spat…
Untangling dust emission and cosmic infrared background anisotropies with the scattering transform statistics
Srijita Sinha, Tuhin Ghosh, Erwan Allys +2
The template-fit approach is often used to separate Galactic dust emission from cosmic infrared background (CIB) anisotropies in low column density regions, under the a…
The multiphase interstellar medium as a common origin for magnetic misalignment and TB parity violation
Andrea Bracco, Ari J. Cukierman, Raphael Skalidis +1
We present an original data analysis and a physical model that provide new insights into the origin of, and relationship between, two observables of the dusty, polarized Galaxy at…
PDRs4All VIII: Mid-IR emission line inventory of the Orion Bar
Dries Van De Putte, Raphael Meshaka, Boris Trahin +135
Mid-infrared emission features probe the properties of ionized gas, and hot or warm molecular gas. The Orion Bar is a frequently studied photodissociation region (PDR) containing l…
A far-ultraviolet-driven photoevaporation flow observed in a protoplanetary disk
Olivier Berné, Emilie Habart, Els Peeters +143
Most low-mass stars form in stellar clusters that also contain massive stars, which are sources of far-ultraviolet (FUV) radiation. Theoretical models predict that this FUV radiati…
PDRs4All III: JWST's NIR spectroscopic view of the Orion Bar
Els Peeters, Emilie Habart, Olivier Berne +135
(Abridged) We investigate the impact of radiative feedback from massive stars on their natal cloud and focus on the transition from the HII region to the atomic PDR (crossing the i…
PDRs4All II: JWST's NIR and MIR imaging view of the Orion Nebula
Emilie Habart, Els Peeters, Olivier Berné +139
The JWST has captured the most detailed and sharpest infrared images ever taken of the inner region of the Orion Nebula, the nearest massive star formation region, and a prototypic…
Dust polarization spectral dependence from Planck HFI data. Turning point on CMB polarization foregrounds modelling
Alessia Ritacco, François Boulanger, Vincent Guillet +4
The search for the primordial B-modes of the cosmic microwave background (CMB) relies on the separation from the brighter foreground dust signal. In this context, the characterisat…
Studying Magnetic Fields in Star Formation and the Turbulent Interstellar Medium
Laura Fissel, Charles L. H. Hull, Susan E. Clark +10
Understanding the physics of how stars form is a highly-prioritized goal of modern Astrophysics, in part because star formation is linked to both galactic dynamics on large scales…
Dust models compatible with Planck intensity and polarization data in translucent lines of sight
V. Guillet, L. Fanciullo, L. Verstraete +6
The dust properties inferred from the analysis of Planck observations in total and polarized emission challenge current dust models. We propose new dust models compatible with pola…
Interplay of dust alignment, grain growth and magnetic fields in polarization: lessons from the emission-to-extinction ratio
Lapo Fanciullo, Vincent Guillet, François Boulanger +1
Polarized extinction and emission from dust in the interstellar medium (ISM) are hard to interpret, as they have a complex dependence on dust optical properties, grain alignment an…
Are Cosmological Gas Accretion Streams Multiphase and Turbulent?
Nicolas Cornuault, Matthew Lehnert, François Boulanger +1
Simulations of cosmological filamentary accretion reveal flows ("streams") of warm gas, ~ K, which are efficient in bringing gas into galaxies. We present a phenomenological…
Structure formation in a colliding flow: The Herschel view of the Draco nebula
M. -A. Miville-Deschênes, Q. Salomé, P. G. Martin +9
The Draco nebula is a high Galactic latitude interstellar cloud likely to have been formed by the collision of a Galactic halo cloud entering the disk of the Milky Way. Such condit…
VLT/ISAAC infrared spectroscopy of embedded high-mass YSOs in the Large Magellanic Cloud: Methanol and the 3.47 micron band
Takashi Shimonishi, Emmanuel Dartois, Takashi Onaka +1
This study aims to elucidate a possible link between chemical properties of ices in star-forming regions and environmental characteristics of the host galaxy. We performed 3--4 mic…

Dust models post-Planck: constraining the far-infrared opacity of dust in the diffuse interstellar medium
Lapo Fanciullo, Vincent Guillet, Gonzalo Aniano +5
We compare the performance of several dust models in reproducing the dust spectral energy distribution (SED) per unit extinction in the diffuse interstellar medium (ISM). We use ou…
Far-infrared excess emission as a tracer of disk-halo interaction
Daniel Lenz, Jürgen Kerp, Lars Flöer +3
Given the current and past star-formation in the Milky Way in combination with the limited gas supply, the re-fuelling of the reservoir of cool gas is an important aspect of Galact…
