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 XV: CH radical and H molecular ion in the irradiated protoplanetary disk d203-506
I. Schroetter, O. Berné, J. R. Goicoechea +20
Most protoplanetary disks experience a phase in which they are subjected to strong ultraviolet radiation from nearby massive stars. This UV radiation can substantially alter their…
Central kiloparsec region of Andromeda. I. Dynamical modelling
Lucie Cros, Françoise Combes, Anne-Laure Melchior +1
The Andromeda galaxy (M31) is the most nearby giant spiral galaxy, an opportunity to study with high resolution dynamical phenomena occurring in nuclear disks and bulges, able to e…
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…
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 new analytical model of the cosmic-ray energy flux for Galactic diffuse radio emission
Andrea Bracco, Marco Padovani, Daniele Galli
Low-frequency radio observations of diffuse synchrotron radiation offer a unique vantage point for investigating the intricate relationship between gas and magnetic fields in the f…
